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.

A welding inspector’s tools of the trade

September 9, 2011 | By David Lucas

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.
