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.

Improving GTAW for producers, fabricators

July 19, 2013

By: ,

Gas tungsten arc welding, a joining process developed decades ago, has been improved by many technology developments over the years, but the essentials are unchanged: It uses an electric arc between a nonconsumable tungsten electrode and the workpiece to produce a weld pool, and it uses a shielding gas. Experiments with brushing on or pasting on mixed metal oxide slurries have shown how this decades-old process can improve dramatically in penetration and speed.

Underwater aluminum GMAW

May 3, 2013

The U.S. Navy has been searching for new weld-repair methods on its aluminum-hulled ships beyond dry docking, which is impractical and costly. Phoenix Intl., an underwater services company that has held the Navy’s Diving Services contract for the past 15 years, may have found one: underwater aluminum GMAW in a hyperbaric chamber.

New guideline reduces manganese exposure limit dramatically

April 19, 2013

By: ,

Chronic exposure to manganese oxide fumes, which occur when manganese metal is heated and reacts with oxygen, can lead to damage to the central nervous system. Welders are especially susceptible to this disease, called maganism by the National Institutes of Health, because manganese is found in many welding rods and filler metals to promote hardness. The American Conference of Governmental Industrial Hygienists recently issued guidance that dramatically reduced suggested threshold limit values. Because many metal fabricators use this guidance to manage worker exposure, they now are having to rethink how they approach personal protective equipment.
