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.

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.
