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.

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?

Virtually welding

March 11, 2008

By:

Today several companies offer technologies that help beginning welders get that hand motion just right. None claims that the technology will replace the real thing, of course, but they do say that training in the virtual world can give students a significant leg up by the time they weld for the first time. It helps teach students what really happens between the welding arc and workpiece, why certain hand motions produce good beads while other motions don't. And it also may help introduce welding to students who wouldn't have given the trade a second thought.

Benchtop Positioner

Putting the spin on benchtop positioners for tube and pipe welding

January 29, 2008

By:

Welding around any kind of circular piece can be a challenge. To make a fillet weld in the horizontal position, you will have to maneuver around the workbench, maintaining a constant arc if you wish to make a continuous weld. This type of work may be acceptable if you need only a few pieces, but can become tedious on production runs. One solution is to rotate the workpiece past the welding arc with a rotating welding positioner, such as a small- to medium-size benchtop machine.
