Purpose of Gouging: Gouging is a welding technique used to remove metal precisely, often for joint preparation, defect correction, or removing old or damaged welds, making it essential for repair and maintenance work.

Common Gouging Techniques: Air carbon arc gouging, plasma gouging, and oxy-fuel gouging are the primary methods. Each technique has unique benefits depending on the type of metal, thickness, and level of precision required.

Equipment Requirements: Gouging typically requires specific equipment, such as air compressors for air carbon arc gouging or plasma cutting machines for plasma gouging, along with specialized electrodes or torches designed for effective material removal.

Safety Considerations: Gouging creates high levels of heat, sparks, fumes, and noise, so proper safety gear is critical, including fire-resistant clothing, goggles, gloves, ear protection, and respiratory protection to guard against fumes.
