Arc Welding

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.

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.

3 ways to boost submerged arc welding performance

April 19, 2013


Submerged arc welding is known as a process that can result in high welding speeds and deposition rates. However, in today's manufacturing reality, engineers are always looking to boost productivity—even for already productive processes. Fortunately, companies have three common approaches to consider to increase the performance of their submerged arc welding systems.
