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.

Welder training essentials: Positioning it right

August 26, 2008

By:

Communicating the right welding position is vital for any welding application. Otherwise, a welder might find himself welding in positions for which he is not qualified--and that's not a good thing.

Submerged arc welding : then and now

July 29, 2008

By:

Submerged arc welding (SAW) is so named because the weld and arc zone are submerged beneath a blanket of flux. The flux material becomes conductive when it is molten, creating a path for the current to pass between the electrode and the workpiece. The flux blanket prevents spatter and sparks, while...

Troubleshooting welding conductivity

June 17, 2008

By:

When MIG welding, are you experiencing an erratic, sputtering arc; a gradual need to increase voltage at the power source; discoloration of copper cable strands or the liner; increased contact tip burnbacks; or inconsistent weld appearance? If so, your problem could be poor conductivity caused by electrical resistance.

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?

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.
