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.

Gas tungsten arc welding (GTAW or TIG), a popular process for high-quality manual welding, has its limitations and requires highly skilled operators. A process used in Europe addresses those limitations, enhances productivity and weld quality, and reduces the skill level required to GTAW.

Of all the welding processes, gas metal arc welding is the easiest to learn. However, setting up a GMAW system isn't quite so straightforward. The wire feed process is all about setup, really, and improper setup can lead to some major problems. If machine settings are incorrect, the welder...

A beginning stick welder can produce better welds by paying attention to the five basic elements to establish a good, consistent technique: current setting, length of the arc, angle of electrode,manipulation of electrode, and speed of travel.

Welding jobs may not be as plentiful as they once were, but welding instructor Marty Rice believes a lot of welding work is "waiting to bust loose once the economy straightens out, and there's always work in welding, if you're willing to pack a suitcase." Rice has some advice for those embarking on a welding journey.

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.

Gas tungsten arc welding (GTAW) often is specified to meet strict aesthetic, structural, or code/standard requirements. The process is complex, and it is undisputedly the most difficult of all the welding processes to learn. The appearance of a GTAW bead can tell you a lot about what you're...

Welding to repair damaged components in broken equipment involves three stages, each of which must be performed meticulously to ensure that the machinery runs properly and the repair lasts a reasonable length of time. What are these stages, and what equipment do you need to complete them?

Stinger Welding Inc. has only been around for 12 years but quickly has established itself as a premier fabricator of bridges and bridge components in the southwestern U.S. Two years ago a projectinvolving an Oakland, Calif., bridge sent the company into thespotlight for its efforts in fabricating 12 girders in just eight days.
