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.

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.

Gas tungsten arc welding isn’t the easiest process to learn. With so many things going on at once, GTAW is a little like juggling while riding a unicycle. With practice, the welder’s eye, arm, hand, and foot coordination will improve.

A process called TIP TIG uses a constant-feed hot-wire that imparts additional energy to the weld. The wire also is superimposed by a secondary high-speed oscillation. The hot-wire’s current combines with the weld-pool agitation to disrupt the surface tension and change the weld dynamics.

When designing and operating a robotic welding cell, don't overlook the consumables. Choosing the wrong consumables can over time lead to serious costs.
Joshua Shaw describes himself as half archaeologist and half fabricator. Those qualities come in handy when he's restoring vintage Sprint race cars, which can provide a number of historical and fabrication and welding challenges. To do it right requires patience and flexible welding equipment.
