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.

Using a purge dam to cut welding time for UHP applications

November 4, 2015 | By Eric Lundin

In welding high-purity and ultrahigh-purity piping systems, quite a bit of the welder’s time is idle, time spent waiting for the purge system to remove the oxygen from the system. Most purge dams mark or scratch the pipe’s ID, neither of which is acceptable on HP and UHP systems. This led to the development of a purge dam specifically for these applications.
