Gouging Methods

Gouging is a method used to melt or fuse metals in a narrow groove using compressed air. It is commonly used to weld joints together

Methods

• There are four common gouging methods. They are mechanical, oxy-fuel, plasma arc and air carbon arc. Mechanical gouging is done through grinding and hand-milling and is widely used in metalworking shops. Oxyfuel gouging is performed using oxygen and fuel gas, while plasma arc gouging is an adaptation of plasma cutting. Carbon arc gouging is ideal for use in mild steel, copper and aluminum.

Techniques

• There are different gouging techniques used by welders. The three common gouging techniques are straight, side and weaving.

Equipment

• Basic gouging equipment includes torches, electrodes, gases and electric power. The type of equipment used depends on the application as well as the gouging method.
