Gouging refers to the process of cutting, shaping, or removing  from metal surfaces using various methods. The primary distinction between gouging and welding lies in their objectives: gouging is aimed at surface preparation or material removal, while welding focuses on joining materials.

What is Gouging functions in welding applications:

1. Preparing surfaces for welding: It ensures that surfaces are clean and free of contaminants for effective weld bonding.

2. Removing defective welds: In cases where previous welds are subpar, gouging helps eliminate these defects, allowing for a stronger final product.

3. Shaping and contouring materials: Gouging allows welders to manipulate and shape materials to meet design specifications or accommodate other parts.
