Gouging: The other plasma process - The Fabricator

Air Carbon Arc Gouging. In the air carbon arc process, an electric arc is generated between the tip of a carbon electrode and the metal workpiece. A jet of air is directed around the tip to remove molten metal from the area, forming a groove.

Air carbon arc cutting - Wikipedia

Air carbon arc cutting previously known as air arc cutting, is an arc cutting process where metal is cut and melted by the heat of a carbon arc. Molten metal is then removed by a blast of air.It employs a consumable carbon or graphite electrode to melt the material, which is then blown away by an air jet.

Preheat for Carbon arc gouging?? - American Welding Society

May 23, 2008· In the case of removal of metal with a carbon arc gouging process the stresses will be introduced as the surfaces that are exposed by the carbon arc process will normalize and likely harden up because of the rapid return to the starting temperature of the part.

Carbon graphite gouging electrodes, Air carbon arc cutting

Carbon Gouging Electrodes for Air carbon arc cutting The gouging process using electrodes has several advantages compared with traditional processes (with pneumatic chisel, grinder, butt welding torch etc. ); it is economical and speedy, friendly to use with noise and danger of

AIR CARBON-ARC GUIDE - webventuresofny.com

Air carbon-arc gouging began in the 1940s, evolving from the existing carbon-arc cutting process. Myron Stepath, a welding engineer, developed air carbon-arc gouging to remove several hundred feet of flat, cracked, stainless steel weld. Previously, carbon-arc cutting removed overhead and vertical defective welds and rivet heads.

Air Carbon Arc Gouging and Cutting, but is included for informational purposes only. These recommended practices have been prepared by the C5 Subcommittee on Air Carbon Arc Gouging and Cutting, of the AWS Arc Welding and Cutting Committee.

Gouging how-to - Welding Productivity

The air carbon-arc gouging process does not require oxidation to maintain the cut, so it can gouge or cut metals that the oxyfuel process cannot. In fact, most common metals (carbon steel, stainless steel, high-alloy wear plate, copper alloys and cast irons) can be cut using air carbon-arc gouging.
