ARC-AIR GOUGING PROCESS
Air Carbon-Arc Gouging (commonly referred to as Arc-Air Gouging) has been used since the early 1940’s when it was
initially developed from the Carbon Arc Cutting process that was used to remove welds, rivet heads and cut metal while
relying on gravity for removal of the molten material. The gouging process was further developed with the introduction
of a jet of compressed air from behind and on the underside of the gouging carbon to remove the molten material. This
compressed air was initially applied by a second operator directing an air gun towards the molten pool and was not very
successful. With great ingenuity and further development, the Air Carbon-Arc Torch was designed whereby compressed air
is fed through the torch head and exited behind and beneath the carbon electrode. The localised air blast provided much
faster and more efficient removal of material from the molten pool. Air Carbon-Arc Gouging now provided a perfect process
for weld removal, crack removal, back gouging and weld defect repairs for carbon steels, alloy steels, stainless steels and
non-ferrous materials.
