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.

Trends in offshore energy

July 28, 2009

The welding industry is known for a persistent shortage of skilled workers, and the energy sector is no exception; meanwhile, offshore welding is getting more rigorous. The easiest-to-find oil sources were discovered long ago; with each passing year, energy companies go into harsher environments (deeper waters) to find petroleum and natural gas. Drilling into deeper waters means dealing with higher pressures and colder temperatures, and many companies have been switching too high-strength pipe, which tends to be more difficult to weld than common pipe.
