What is a welding process using the oxyacetylene rig called?

1. Brazing

2. GMAW

3. SMAW

4. Spot Welding

The correct answer is: Brazing

The welding process using the oxyacetylene rig is called brazing. Brazing is a welding technique that uses a filler metal to join two pieces of metal together. This filler metal, usually in the form of a rod or wire, is melted using the heat from the oxyacetylene torch and flows into the joint, creating a strong bond between the two pieces of metal. Option B, GMAW, stands for Gas Metal Arc Welding and does not use an oxyacetylene rig. Option C, SMAW, stands for Shielded Metal Arc Welding and again does not incorporate the use of an oxyacetylene rig. Option D, Spot Welding, is another welding process that does not involve the use of an oxyacetylene rig, but instead uses pressure and the passage of an electric current to join two pieces of metal together.
