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.

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.

Weld inspectors, especially those who are new to the trade, put a lot of emphasis on the equipment needed to do the job: flashlight, mirror, high-low gauge, pit gauge, bridge camera, and a borescope. However, this isn’t the entire toolkit. A weld inspector also must be cognizant of the applicable codes, knowledgeable about the project owners’ specifications, and should carry a personal log book for making notes about conversations and inspections.
