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.

The lowdown on low-alloy filler metals

June 17, 2008

By: ,

When welding a chromium-molybdenum alloy, selecting the optimal filler wire is critical to the long-term durability of the weld. Fortunately, matching the filler metal to the alloy is no more difficult than it is for matching a filler metal to any other family of alloys. Understanding the chemical and mechanical properties of the materials can go a long way in making strong, corrosion- and creep-resistant welds.

Automation training for a new work force

May 13, 2008

By:

AWS predicts that by 2010, the demand for skilled welders will outstrip supply by 200,000. One means of addressing the shortage is through automated systems, such as automatic orbital GTAW units, which have gained favor in a variety of industries. But that does not diminish the requirement for an educated and well-trained work force. Automation requires more training, not less. That is why it is essential to be trained in basic welding procedures in addition to operating automated welding equipment.

Modified GMAW for root passes

April 15, 2008

By:

Many fabrication shops that do a lot of stainless steel tube and pipe welding are in a bit of trouble these days. The problem isn't a lack of work, of course—it's a matter of trying to handle too much work with too few resources (skilled welders). They can ask their fabricators to work harder or faster, but that goes only so far. Can a new technology help them get more output from their existing employee base?
