To weld metals together, high temperature is required. Such a high temperature is obtained by burning:

Options

  1. AAcetylene in oxygen
  2. BLPG in oxygen
  3. CMethane in oxygen
  4. DAcetylene in nitrogen

Correct answer

A. Acetylene in oxygen

Step-by-step solution

Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding) and oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals.
