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.

A shop is only as productive as its constraint process—that is, its bottleneck. All that adaptability in upstream processes may not make a part cost less if it takes days or weeks to build a new weld fixture. A modular approach to weld fixturing can help.

Mississippi metal artist Stephanie Dwyer never knew she was an artist until she relocated from Washington and began building bottle trees. Today her bottle trees can be found all over the U.S., which has led to opportunities in custom metal art fabrication.

Shielding gases do more than just protect the weld from atmospheric contamination. The gas and gas blends you use also influence the weld profile and the weld bead shape. Also, for an arc to occur in gas metal arc welding (GMAW), an ionized gas must be present to carry the charge.

Super Bowl XLVI in Indianapolis earlier this year featured athletic prowess and classic gridiron toughness with a little speed and finesse. But also on display outside the stadium throughout the heart of downtown was a combination of strength and artistic flair that only a metal art sculpture can provide.

Portable calibration units allow you to perform quality assurance maintenance themselves by calibrating critical welding variables on-site. These remote servicing capabilities bring support closer to the jobsite, improving the uptime and functionality of the power supply and eliminating the need to send it off-site for calibration.

The concepts of positioning are the same for all weldments, large or small. A properly positioned weldment, regardless of the size, reduces welder fatigue, increases safety, improves weld quality, and saves on production floor space.
