The arc welding technology area focuses on the most commonly used arc welding processes, mainly GMAW/MIG, GTAW/TIG, SMAW/stick, and plasma. The articles and press releases cover processes and power sources, plus all of the related items—electrodes and wire, wire feeders, fixtures, manipulators, positioners, and power sources. If you need information on personal protective gear, ventilation systems, and safety practices for welders, see our Safety coverage area.

The push for lighter, corrosion-resistant components has brought aluminum to the forefront of the minds of traditional steel fabricators. Those that approach the material the same as steel often run into weld quality issues that can prove costly. But those who are committed to putting together a topnotch, aluminum-friendly system before striking an arc—from equipment and setup to material preparation and welder education—are better equipped to find success afterward.

A career in code-level welding involves an odd concoction of hands-on work, excellent hand-eye coordination, on-the-job focus, and a dash of lawyerlike thinking. Some can be loud extroverts who get the most attention, but others can be quiet introverts. Many share a dedication to the welding craft, and the best strive to do the job right the first time.

Cup walking, a tube or pipe gas tungsten arc welding (GTAW) technique suitable for some stainless steels, can improve weld quality. The method involves resting the torch’s cup on the workpiece and making a weaving motion across the weld joint. Used properly, it also reduces operator fatigue and can improve weld speeds.

In a 2010 survey from the Fabricators & Manufacturers Association, respondents cited welding as the most sought-after, difficult-to-find technical skill. But at Mitchell's Specialized Fabrication, managers don't look for that experience. They look for someone with a good attitude, eager to learn.

Metal-cored wire typically costs more than solid wire, but the benefits often offset the per-unit price. In reality, any consumable comprises a relatively small portion of overall welding costs; in fact, material and labor make up the lion’s share of welding expenditures. But in the right application, an increase in filler metal costs may lead to greater savings elsewhere.
