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.

Up with energy prices and wind towers - Automation, consultation help plate fabricator meet demand for wind tower masts

February 7, 2006 | By Sue DiBianca

With the recent increases in gasoline and natural gas prices, more attention than ever is focused on alternative energy sources. One fabricator, Aerisyn LLC, investigated manufacturing towers for use in the wind power industry. To produce towers efficiently enough to compete against imports from Asia, Aerisyn relied on an equipment vendor that had experience in demanding fields such as aerospace, nuclear, and wind power.

Elements of success:

January 10, 2006 | By Mike Sammons, Bill Giese

Torches, cables, and cooling are three integral components in gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) equipment, and two cooling methods – air and water – are used in their cooling systems. Although GMAW and GTAW are different processes, the advantages and disadvantages of water- and air-cooled systems are the same. For that reason, you should consider similar factors when choosing a GMAW or GTAW system.

No good deed goes unnoticed

September 13, 2005 | By Stephanie Vaughan

Being a good welder often means more than on-the-job performance. Whether it's volunteering to help others or otherwise giving back to one's community, these welders are examples of so many who take their time to give of themselves on the job — and outside the office.

Resolving the challenges of welding coated steels

September 13, 2005 | By Kevin Lyttle

The increased use of coated steels has resulted in an intensified search for solutions to the problems posed by joining these materials. High levels of spatter and welding fume, weld porosity, and poor bead shape are common. These problems lead to increased post-weld cleaning costs, reduced quality, greater rework, and an overall reduction in productivity. The right wire size and type, matched with the most appropriate shielding gas, can substantially improve gas metal arc welding (GMAW) performance on galvanized and coated steels.

Welding rolled pipe in the 1G position efficiently

July 12, 2005 | By Butch Weidner

For welding in the 1G position (in which the tube or pipe rotates), solid wire is traditional filler metal. However, metal-cored wire is making headway as an alternative. Metal-cored wire requires no land at the bevel, is more forgiving of welding dirty metal, produces less spatter, and allows travel speeds up to inches per minute.
