1.Principle
Gouging is the use of electric arc between the carbon rod and the workpiece heat generated by the metal melt. With compressed air to blow off the molten metal. So that the metal of a heat-planing processing groove.
2 Features
1) carbon arc gouging and compared with wind shovel or wheel. High efficiency, low noise, and reduce labor intensity.
2) carbon arc gouging and plasma arc gouging compared. Simple equipment readily available and low cost air.
3) Since carbon arc gouging is not the use of high temperature oxidation gouging metal. Thus not only apply to black metal. But also for stainless steel, aluminum, copper and other nonferrous metals and alloys.
4) Due to the carbon arc gouging is using compressed air to blow the molten metal. Thus can be all-position operation. Handmade carbon arc gouging flexibility and maneuverability better. Thus the station in a narrow or poor accessibility of the site. Carbon arc gouging can still be used.
5) When removing welds or casting defects. Is planed smooth surfacing burnished. In the arc can be clearly observed in the shape and depth of the defects, so it is beneficial to remove defects.
6) carbon arc gouging also has significant drawbacks. Such as smoke, noisy, dust pollution, arc radiation, the operator's technical requirements.
