1.2 GENERAL ABOUT CARBONARC GOUGING
Carbon-arc gouging refers to a method where metal is removed by melting it with a welding
arc and blowing the melted metal away with compressed air.
Carbon-arc gouging can be used with the majority of metals, such as steel, stainless steel, cast
iron, nickel, copper, magnesium and aluminium.
The equipment used in carbon-arc gouging comprises the gouging power source, a carbon
holder and its cables, and the gouging carbon, which can be round or at. Also a sucient
compressed air supply must be available.
A round gouging carbon can be used in:
• opening a root weld
• opening faulty welds and cracks
• manufacturing welding grooves
• cutting metal
• making holes

A at carbon can be used in:
• arc grading of surface errors in roller slabs
• cleaning steel casts
• opening faulty casts
• arc grading of weld caps
