What is Air Arc Gouging
Air arc gouging (also known as air carbon arc gouging) is a metal removal process that uses an electric arc and a stream of compressed air to melt and remove metal from a workpiece. It’s commonly used in welding, fabrication, and repair work to gouge out defective welds, prepare surfaces for welding, or remove unwanted material.
How It Works:
- Electrode: A carbon-graphite electrode is used to create an electric arc between the electrode and the metal surface.
- Arc Heat: The arc generates extreme heat, melting the metal.
- Compressed Air: A high-velocity jet of compressed air blows away the molten metal, creating a groove.
Key Features:
- Versatile: Can be used on various metals, including steel, stainless steel, and cast iron.
- Efficient: Removes metal quickly without excessive grinding.
- Common Applications:
- Removing old welds
- Preparing joints for welding
- Cutting out defects
- Creating grooves for rewelding
Equipment Required:
- A DC welding power source (usually constant current)
- Carbon-graphite electrodes (often copper-coated)
- Compressed air supply (minimum 80 psi, depending on the job)
- Personal protective equipment (PPE) due to sparks and metal splatter
Advantages Over Other Methods:
- Faster than grinding or chipping
- More precise than oxy-fuel cutting for gouging applications
- Can be used in various positions (flat, vertical, overhead)
