Both new and professional welders may take advantage of the many employment opportunities, specifically industrial welding jobs, MIG welding jobs, TIG welding jobs, welding inspector jobs, pipe welding jobs, rig welding jobs, and underwater welding jobs. The key to landing the best, most financially rewarding welding jobs is to acquire the necessary skill set to excel in one or more of these welding applications.

Various Welding Types Provide Welding Jobs

To date, arc welding remains the most widely used welding method, under which fall MIG, TIG, plasma arc, and submerged arc welding. Commonly employed in high-volume projects, these welding forms provide the best opportunities in fusion welding.

Also on the rise is laser welding, a new welding technology that is paving the way for additional welding jobs. So is ultrasonic welding, a field in which those with experience in plastics or micro joining will find income opportunities.

Employment seekers may also find opportunities in sectors or industries that employ resistance welding. The automotive industry, for one, relies heavily on spot and seam resistance welding work. Hence, those with extensive experience in the automotive industry stand a better chance of getting hired for resistance welding positions.

Most employers favor welders armed with auxiliary skills. Such skills enable employed welders to perform their welding job with utmost care and precision, and give applicants a competitive edge over other job hunters.

Education and Training Requirements

A welding career involves long hours spent in a variety of work environments. The financial rewards are attractive though. It is therefore important to equip oneself with the necessary skills and knowledge, particularly in problem solving, mathematics, blueprint reading, and computers. The widespread use of automated welding systems has necessitated computer literacy among welders.

For those who are really keen on building a welding career, the first step should be to take a course in welding technology. The completion of this course at a local community college or a welding school is one’s passport to gainful employment, particularly to welding jobs such as welder or welder’s helper. These schools teach students how to perform welding on both ferrous metals such as steel and non-ferrous metals such as aluminum. They also introduce enrollees to emerging welding technologies such as computerized welding, which enables the programming and operation of an automated, computer-controlled welding system.

Today most companies offer apprenticeships to aspiring welders, with certified welders training them on the job and helping them acquire and develop as many skills as needed.

The secret to accumulating relevant welding experience is by training as an apprentice. As soon as a student earns a degree or certificate, the next best step is to seek out companies offering welders apprenticeship programs.

After several months of on-the-job training under the supervision of a certified welder, applicants may take the required certification test for the specific welding method (e.g. MIG, TIG, stick) that their would-be employer specializes in. Welders may obtain as many certifications as needed and get re-certified from time to time to be able to perform a variety of welding jobs.

Arc Welding: Widely Used, Versatile Welding Process

Arc Welding

Developed in the 1940s, arc welding remains a popular welding method to this day. Many industries, from manufacturing to shipping to automotive, use arc welders given their ease-of-use and cost-efficiency.

Advantages of Arc Welding

By far the simplest welding technique, electric arc welding is favored by many industries because of the availability of a wide range of easy-to-use-and-transport welding rods or filler metal. Although mastering it may take some time, many small automotive shops and fabrication businesses rely heavily on this method by virtue of its versatility.

The main difference between arc welding and MIG welding lies in the former’s use of flux-coated arc welding rods usually measuring 12 inches long. MIG welders, on the other hand, are typically wire-fed. Serving as the arc welding electrode is a rod made of steel, stainless steel or aluminum. The rod is coated with flux material that acts as a shield for the weld pool during welding. Oxides, fluorides, carbonates, and metal alloys mix to form this flux coating  that surrounds the rod. The coating in turn cleans the hot weld bead as it cools, making sure the weld is not impacted by the atmosphere.

Changing the electrodes and inserting them into the electrode holders can be quick and effortless. However, many welders engaged in bigger projects favor wire-fed MIG welding, as changing arc welding electrodes usually slows down the welding process.

With arc welding, welders have a choice of using either alternating or direct current. Because they are cheaper and easier to manufacture, AC output welding machines are still favored by welders throughout world. Today, however, more and more welding machines are offering both AC and DC output, allowing users to select the output that would best serve the job at hand.

Most commonly used welding tools

People everywhere appreciate the value of the arc welding machine, specifically its lower cost and wide availability, portability, adaptability to various weather conditions, and durability. Except for the fan, parts replacement is not necessary.

Arc welders come in many shapes and sizes, from portable DIY home hobby machines to large three-phase industrial units. Farmers use them to repair tractors and farm machinery while welders and boilermakers use them for pipe welding.

Welders may choose from among various arc welding equipment to perform arc welding. For stainless steel, low alloy steel, and nickel alloys, flux-core welders will deliver the best results. In flux-core welding, an arc welder fuses metal pieces together by pointing the hot arc between a filler metal electrode and the metal being fused. This welding tool is best for welding jobs at home or in automotive shops and other facilities requiring minimal fabrication or arc welding.

Also widely used in welding and other industries are gas metal welders. Known for their precision, gas metal welders are mostly handheld and portable, allowing users to bring it anywhere for use in a variety of materials. Today, however, this welding tool is still mainly used on metals like aluminum, stainless steel, and magnesium, even if it can work with most types of metals including zinc and lead. Users of this particular arc welder laud the extremely high quality of the finished weld, particularly its smooth, clean, and splatter-free finish. Such strengths make gas metal welders the best tool for arc welding on large areas of car bodywork.

MIG Welding: Speedier, Cost-Effective Welding Technique

MIG Welding

Metal Inert Gas or MIG welding, occasionally referred to as Gas Metal Arc Welding, traces its roots to the 1940s when it was first used to weld aluminum and other non-ferrous metals. In the MIG welding process, a wire connected to a direct current source serves as the electrode needed to join two pieces of metal—the electrode always transmitted through a welding gun. Together with the wire electrode, a flow of inert gas such as argon also surges through the welding gun. Acting as a shield, the inert gas drives away airborne contaminants from the weld area.

Benefits and Drawbacks of MIG Welding

MIG welding, an automatic or semi-automatic welding method, is preferred by many as it is faster and easier to perform compared with manual stick welding. It is best used for welding softer metals like aluminum, which can easily sustain holes with the use of a slower-paced machine. While inert gas was rare in yesteryears, today MIG proponents can turn to widely available carbon dioxide as a means of shielding against contaminants. This has in turn made this welding process one of the most cost-effective.

On top of its compatibility with softer metals, MIG welding provides cleaner welds and can accommodate many other types of metals. Welders employing this method can expect to create long, continuous welds much more quickly than when they use other traditional techniques.

On the other hand, MIG welding equipment can prove more complicated as the process requires not just a direct current source and a constant source and flow of gas, but also a constantly moving wire electrode. Sold in various sizes, electrodes are made of different metal types to suit a wide range of welding applications.

Both newcomers and professional welders may have to spend more time and effort mastering MIG welding techniques, given that it works differently compared with traditional welding methods. For one, it requires welders to move the welding puddle away from them and along the seam. Further extending the learning curve is the fact that MIG welders must hold wire feeders and rely on continuously fed MIG welding wire using one setting, then later adjust the settings based on the type of material being welded.

MIG welding’s cost efficiency has made it the preferred welding method in the manufacturing industry. Automakers favor it for its clean welds and the speed by which it can be performed. Today, there are plenty of MIG welding opportunities in companies and industries requiring welding jobs on non-iron surfaces. The manufacturing, construction, and shipbuilding industries are top providers of MIG welding jobs as their production processes often require repair or maintenance work aided by MIG welding.

MIG welding machines come in various forms to suit a wide range of applications. Some require manual operation while others are capable of semiautomatic welding. Also available are units designed to perform automatic or machine welding.

In this welding process, the electrode is continuously fed, thus requiring a sliding electrical contact for the welding gun for it to be able to transport the welding current to the electrode. The gun must also be quipped with a nozzle and gas passage that will direct the shielding gas to the welding arc’s surrounding area and the weld pool. Because shielding MIG welding gas is used, MIG welding is often performed indoors and in other enclosed, windless areas.

TIG Welding: Cleaner, Burn-Free Welding Method

TIG Welding

TIG welding, also referred to as Gas Tungsten Arc Welding, is a manual welding method that requires the use of both hands. The manner by which the arc is created and the filler metal is added is what differentiates TIG welding from other welding processes. Welders performing this welding type use one hand to hold the arc-producing TIG torch and the other hand to add the filler metal to the weld joint. As it requires the use of both hands, TIG welding can be one of the most challenging welding methods. However, it is the most versatile, it being applicable to most metal types. While more time-consuming, TIG welding jobs can produce the best weld when performed precisely. Major applications include critical weld joints, welding of metals other than common steel, and precise, small welds.

How TIG Welding is Performed

Considered a far cleaner method than arc or MIG welding, the TIG welding process is most appropriate for welding car panels, custom motorbike frames, handrails, among others. It requires less rework time as welders do very little cleaning and removal of excess welds.

Heat, shielding, and filler metal are the three key elements involved in TIG welding. Electricity surging through the tungsten electrode generates the heat, specifically by creating an arc to the metal. A compressed bottle of gas flows to the weld area to protect it from the air, thus providing the shielding. A wire dipped by hand into the arc and thereafter melted becomes the filler metal.

The process begins with the welder activating the gas flow through a valve on the TIG torch. This causes the gas to flow and start shielding the weld area against the air. The welder then holds the torch just above the weld joint, making sure the torch does not touch the metal. By pressing a foot pedal, the welder causes the TIG torch to produce tungsten electrode and create an arc.  The moment an arc surfaces, the two pieces of metal start to melt, thereby producing a puddle of metal. The welder then uses his other hand to fill the joint, specifically by dipping a welding wire into the arc. A single piece of metal comes out of this process.

The TIG welding torch produces a constantly burning electric arc. Those who have experience using oxy acetylene for welding will have no problems operating a TIG welding machine. TIG welding simply uses the heat from the electrical arc to melt the base metal. Shortly after a metal becomes molten, it melts altogether to form a weld, better known as fusing the metal together. Hence, small welds need no more than fusing the metal pieces together. Bigger welds, on the other hand, require the use of a filler rod.

Why is it more advantageous to use tungsten for welding jobs? The hard, brittle, and slightly radioactive tungsten used in welding TIG turns into a non-consumable electrode that produces the required arc. In TIG welding, tungsten’s metal properties enable an arc to withstand temperatures as high as 11,000 degrees Fahrenheit. Welders can therefore rest assured that the tungsten electrode will never burn up, given tungsten’s high melting point and superior electrical conductivity. This is perhaps one of the reasons why TIG welding remains a popular welding method to this time.

Spot Welding: Fastest, Most Energy-Efficient Welding Technique

Spot Welding

Welders opt to use the spot welding method to quickly and easily melt and weld a spot in a material without affecting its other parts. The process therefore requires the application of concentrated energy on the spot being welded. Resistance to electric current flow produces the heat needed for welding. The pieces to be welded together are fused by pressure exerted by electrodes. Welders typically use copper alloy electrodes to weld two sheets, usually 0.5 to 3.0 mm thick, together in a spot. The resistance to the electrodes and the amplitude and duration of the current all determine the amount of generated heat. Inappropriate amounts of energy will not produce the desired welding quality.

How Spot Welding Works

Spot welding begins once the electrodes are brought to the metal’s surface and some pressure is applied to it. The next phase involves the brief application of the current derived from the electrodes. Finally, the current is removed while the electrodes stay in place to allow the material to cool.

Weld times run from 0.01 seconds to 0.63 seconds, depending on the material and its thickness, the electrode force, and the diameter of the electrodes. The process requires the use of tool holders and electrodes. Usually made of copper or other low-resistance alloy, spot welding electrodes are available in various shapes and sizes, conforming to specific welding requirements. Meanwhile, welders rely on tool holders to keep electrodes in place and hold water hoses that cool the electrodes during the welding process.

In spot welding, the two materials being fused together, commonly referred to as workpieces, must conduct electricity. Once the current is taken out of the workpiece, the coolant holes found at the center of the electrodes step in to cool it. The most common coolants are water and brine solution.

Spot Welding Benefits and Applications

Speed, control, and automation are the three key strengths of the spot welding process. It does not produce unnecessarily large amounts of heat as the current transmitted through the electrodes moves in milliseconds. This makes this method far less dangerous and more energy-efficient than other methods. It also allows maximum control of welding current, thus producing longer-lasting welds. Professional welders and auto repair specialists use portable spot welding machines. However, robots are known to perform the best spot welds, and are generally used by automakers. Today’s automotive assembly lines feature swiveling robotic arms capable of producing precise currents and  performing large amounts of strong and lasting spot welds.

Spot welding finds its use in a variety of welding jobs and applications, as well as in different types of metal sheets. It is widely used in the industrial, construction, and commercial sectors.  Powerful welding transformers allow spot welding aluminum alloys. The automotive industry uses spot welding machine to join metal sheets during vehicle manufacturing. Orthodontists are also top users, employing small-scale spot welding equipment to adjust or resize metal molar bands. This welding method also plays a key role in battery production, specifically nickel-cadmium and nickel metal hydride batteries. Spot welding fuses battery cells, joining thin nickel straps in the battery terminals. Spot welding, unlike soldering, keeps the batteries from getting too hot.

Welding Helmets: Shielding Welders Against Harmful Emissions

Welding Helmets

Welding helmets are by far the most effective and reliable safety gear that welders must own and use. Since the first time they were used, wedding helmets have taken various forms and sizes, and have improved in terms of user-friendliness, durability, and functionality. To date, however, many users remain in the dark as to how a welding helmet actually shields them against the potential health and environmental hazards associated with welding.

Benefits of Wearing Welding Helmets

Most people think of welding helmets as extra-large sunglasses that serve to protect one’s eyes from the blinding lights created by welding arcs. They actually go beyond that. Helmets’ lenses filter out 100 percent of harmful ultraviolet and infrared rays from welders’ sensitive eyes. By no means does the color or darkness of the lens determine its filtering abilities. Whether clear or darkened, an auto darkening lens will effectively shield one’s eyes against UV light. True enough this blinding light is the most highlighted risk, it being the most visible to the naked eye. The potential damage this light poses to the eye makes welding helmets with darkened lens or auto darkening feature a must-have for all welders.

The lens of auto darkening welding helmets dims within 4/10 millisecond to filter out visible light. Welders would do well to avoid purchasing models with darkening speeds lower than that. More specifically, auto darkening helmets, regardless of lens color or darkness, completely shield one’s eyes against UV and infrared light, and protects users from visible lights in 4/10 millisecond after the lighting of the arc. This helmet type is no doubt much safer than its older counterparts, as it lets users know when the arc has already been extinguished. The auto darkening lens becomes clear as soon as welding ceases, allowing welders to move around and see clearly without taking off their auto darkening welding helmet. Whether or not they are working, welders must remain helmeted and protected inside the work area, particularly against flying objects such as metal debris.

Such features and functions make auto darkening models the best welding helmet for welders. Although costlier than other helmet models in the market, the advanced technology that powers them promises to protect welders’ eyes from the harmful effects of welding light 100 percent of the time, darkening as quickly as needed to shield every eye.

High-Quality vs. Inexpensive Welding Helmets

Those who choose to purchase low-priced wedding helmets may have difficulty getting spare parts in case of damage or defects. Spare clear lenses or spare head straps are usually hard to find, even at shops selling these helmets.

Helmets that satisfy ANSI standards typically filter out most of the harmful UV and infrared emissions created by welding arcs.  However, lower-priced welding helmets for sale are known to have only one shade setting. Higher-quality models, on the other hand, have from 9 to 13 shades of darkness, thereby allowing welders to perform a wide range of welding jobs, from low-amperage TIG welding to heavier stick welding and flux core welding. Furthermore, their adjustable controls inside enable premium-grade welding helmets to switch to their filtered welding mode at rates much faster than those of ordinary helmets.

Underwater Welding: When Repairs Have to Be Done Beneath the Surface

Underwater Welding

Contractors and their welders use underwater welding for metalwork, repairs, and other welding jobs that need to be completed underwater. The restoration of damaged ships is one example of work that requires this specific welding type. It is a highly specialized welding technique that requires underwater welding training, preferably at underwater welding schools, on the part of welders. Under water welding counts the shipping industry and the defense sector as its biggest users.

More specifically, underwater welding finds its most important applications in the manufacture of marine engineering products as well as in oil and gas rig installations. It can take several forms, based on the type of equipment and procedures involved. Manual metal arc building (MMA) remains by far the most popular underwater welding method, commonly used for deep water repair work. Other commonly employed underwater welding techniques include cofferdam welding and hyperbaric welding, both of which are most suitable for welding steel pipelines, other offshore structures, submerged parts of major vessels, and underwater structures supporting a harbor.

Underwater Welding Categories

Underwater welding has two main categories: wet welding and dry welding. The wet welding process is always carried out under water and exposed to wet environments, thus requiring a special type of electrode. It is performed manually, affording welders freedom of movement. Cables and hoses connect the welding power supply unit on the surface to the welder working underwater.

Most welders consider this technique the most reliable, effective, and cost-efficient.

Wet welding is preferred by many for the minimal costs it involves and the speed and ease with which it can be carried out. Underwater welding jobs require minimal and the simplest of equipment, thus enabling welders to complete welding jobs more quickly and with little planning and preparation.

On the other hand, some welders claim that welds created via the wet method are often quenched easily underwater, thus decreasing their strength and ductility, and rendering them very porous. Moreover, in welt welding, welder visibility falls below the required level while voltage levels used can be quite limited.

Dry welding, also called hyperbaric welding, is typically performed within a sealed, gas-filled chamber surrounding the structure to be welded. The chamber is filled with a breathable mixture of air and inserted into the pipeline. Using high pressure, dry underwater welding generally employs the gas tungsten arc welding or TIG welding process.

Many welders favor dry welding over its wet counterpart because it can be done minus such worries and dangers as ocean currents and deadly marine animals.  Aside from producing higher-quality welds, this method allows welders to visually monitor preparation and pipe alignment from the surface.

Among its drawbacks are its relatively high cost and the complexity and limited reusability of the chamber used, which requires the presence of large support underwater welding equipment at the surface.

Risks Associated With Underwater Welding

Underwater welding exposes both the welder and the structure being welded to danger. The welder must therefore be insulated and protected against electric shocks. There is also a need to control the voltage of the welding sets. The arc will also create potentially explosive pockets of oxygen and hydrogen. Welders run the risk of having nitrogen buildup in their bloodstreams, particularly when they are exposed to air at high pressure underwater.  All these risks have made inspection a mandatory though challenging safety procedure. Welders, inspectors, and regulatory agencies must work together to ensure the safety of all underwater welding jobs.

Welding Supplies: Tools, Equipment Serious Welders Must Have

Welding Supplies

Professional welders and hobbyists with a keen interest in welding must have the necessary welding supplies to get any welding work done well and according to specifications. The discipline is in itself challenging enough, requiring not just skill and know-how but the right equipment as well. With adequate welding supply, skilled welders can efficiently perform various repair, construction,  and metal works. Job quality usually suffers when welders stop in the middle of a weld because a certain material has run out. Hence, it is important to make sure that all the required equipment and material including safety devices for protection are on hand prior to starting welding jobs.

Most Important Welding Supplies

The market offers a vast range of welding supplies. Welders must maintain an extensive welding supply consisting of abrasives, chipping hammers, consumable electrodes, cylinders with custom carts, grinding wheels, ground clamps, and electrode holders. TIG consumables may also be required, depending on the type of welding work being undertaken.

Among all welding supplies however, power or energy sources play the most crucial role in the welding process. Welding practitioners must purchase and maintain high-performance generators that ensure a constant supply of energy. Before making a selection, it would be wise to first determine the exact position or location of the welding generator, or whether a portable model would be most beneficial.

Also ranking high on every industrial welding supply list are electrodes or what most welders refer to as welding rods. To avoid unnecessary work interruptions, welders would do well to have replacement parts or supplies on hand for the different welding tools and equipment they regularly use.

The risks associated with welding are well known, thus, it is important to take precautionary measures to avoid accidents and injuries on the job. Safety equipment can go a long way in minimizing if not totally eliminating the possibility of sustaining minor and severe injuries while performing welding work. Welders can work with total peace of mind when they use safety welding supplies such as eye and face protection (helmets), gloves, first aid kits, protective clothing, hearing protection, respiratory protection, among others. It is also recommended that an adequate supply of such safety devices is conveniently stored in the work area.

One welding supply people often overlook is protective footwear, which effectively shields welders in the event that heavy metal pieces or molten metal fall and hit their feet  and other body parts.

Higher-quality welds and greater efficiently are also results of sufficient miscellaneous welding supplies in the workplace. These include brushes and brooms, tape, cable ties, tie downs, tarpaulins, and vacuums. It is also a must to keep the welding area and all welding equipment free of contaminants, so make sure to buy welding clamps and the necessary cleaning tools and agents.

Adequate welding supply would also benefit welding shops and businesses, specifically in terms of operational costs and efficiency. The best way to manage material and equipment costs is to find the most reliable and price-competitive welding suppliers and welding supply store for materials bought in bulk on a regular basis. Late or incomplete deliveries on the part of suppliers can cost welding shops and projects a lot in terms of man hours and worker productivity. Hence, even if a business has a reliable supplier serving it, it would still be wise to have adequate welding supplies on standby, so that in cases of emergencies and unforeseen work interruptions, welding operations can still be carried out.

Welding Schools: Laying the Foundation for a Welding Career

Welding Schools

Welding schools serve as the best launching pad for those dreaming of a career in welding. These academic institutions provide the solid foundation that aspirants need not just to land the best jobs in vital industries such as construction and manufacturing, but more importantly, to excel in and contribute to the growth of the welding domain.

Welding often forms part of the comprehensive training programs that manufacturing companies conduct for their employees. However, aspirants who wish to develop the skills needed to penetrate the welding field enroll in secondary vocational schools, local community colleges, welding trade schools, or technical schools that offer relevant courses and training programs. Today, almost all companies that employ welders require formal education obtained from welding schools. Armed with program certificates or associate’s or science degrees, welders join the industry with confidence that they can easily find and efficiently perform various welding jobs, specifically in construction firms, factories, and power plants.

What Students Learn at Welding Schools

Students of welding schools, particularly those working toward an associate’s or bachelor’s degree, attend classes in general subjects such as physics, mathematics, chemistry, mechanical drawing, and computer. At the same time they undergo actual skills training from which they learn various welding concepts, theories, and applications, and gain hands-on experience in welding work.

Welding courses offered by most welding schools normally run from 8 weeks to 7 months. Such programs initially introduce enrollees to basic welding principles before they teach skills such as blueprint reading and how to perform various welding techniques. Specific courses include arc welding, pipe welding, metallurgy technology, and inspection techniques. Students learn the various principles and aspects of welding, including safety measures, through a combination of classroom lectures and hours of hands-on training.

Tips on Choosing the Right Welding School

Before enrolling in any welding school, students must make sure that the institution is accredited and offer fully accredited training programs. An accreditation indicates that a school for welding has fully complied with the standards set by accreditation bodies, specifically in the areas of curriculum quality and relevance, teaching staff qualifications, and facilities and resources. By enrolling in accredited schools for welding, students can rest assured that they will acquire the knowledge, skills, and experience they need to pass certification exams such as the Certified Welders Test administered through the American Welding Society (AWS).

Today the top welding schools in the U.S. include the Tulsa Welding School, Hobart Institute of Welding Technology, and Lincoln Welding Training Program. These schools offer welding programs designed to prepare students to hurdle the required certification test and get good-paying jobs as certified welders.

Tulsa offers structural welder and master welder programs. Most students opt to enroll in its master welder program as it teaches all the major welding techniques including TIG, stick, MIG, and flux core, through the use of structural plates, pipes, and thin sheet metal.

Hobart, on the other hand, offers shorter, very specific, and more affordable training courses like titanium TIG welding on top of its regular structural welder and master welder programs.

Accredited welding schools normally have financial assistance programs for deserving students. Students who have the required academic credentials but not the financial resources to enroll in a comprehensive training program may take advantage of the institutional grants or scholarships offered by these schools. Meanwhile, the AWS also assists qualified but financially handicapped aspirants through district scholarships.

By providing the best skills training and education, duly accredited welding schools lay for future welders the groundwork for a challenging albeit financially rewarding career.
