Arc Welding Articles

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.

By:

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.

Cup walking on stainless steel tube, pipe

April 11, 2012

By:

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.

How metal-cored wires reduce hidden welding costs

April 3, 2012

By:

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.
