Which welding process uses an oxy-acetylene flame to weld metal when arc welding is not available?

• A. MIG welding
• B. Oxyacetylene welding
• C. TIG welding
• D. Brazing

Answer: (B)

Oxy-acetylene welding uses a flame produced by burning acetylene in oxygen to heat the metal until it fuses, and it doesn’t rely on electricity. This makes it ideal when an electric power supply for arc welding isn’t available, since you can carry the torch and gas bottles to the job site and weld directly. It’s a flame-based heating method, distinct from MIG or TIG, which require an electrical arc, and from brazing, where the base metal isn’t melted and a separate filler metal is used.
