1. Plasma Gouging

Plasma gouging uses a high-velocity jet of ionized gas to melt and blow away the material being gouged. This method is particularly effective for various metals and offers high precision and minimal thermal distortion.

2. Air Carbon Arc Gouging

This traditional method utilizes a carbon electrode and an air jet to create a molten pool that is blown away from the workpiece. It is commonly used in heavy industrial applications

3. Oxy-Fuel Gouging

Using a flame produced by burning acetylene and oxygen, oxy-fuel gouging melts the material, which is then removed by the force of the flame. This method is often utilized for steel and cast iron.

4. Mechanical Gouging

This technique involves using mechanical tools such as grinders or milling machines to remove material. It's often used for precision work and in situations where other methods may not be feasible.
