Air arc gouging

Arc gouging is a metal cutting and welding process that uses an electric arc to melt and remove metal from a workpiece. In this process, an electric arc is created between the workpiece and a carbon electrode, which is slowly moved across the surface to be cut or welded. As the arc melts the metal, a high-pressure air stream blows away the molten metal, creating a groove or hole in the workpiece. Arc gouging is typically used to remove metal from thick sections of steel or other metals, where ot
