Answer
Correct Answer: Oxygen and acetylene (oxy-acetylene welding)
Explanation
Given data
- Context: Welding gases.
Concept/Approach In oxy-acetylene welding, acetylene (C2H2) is the fuel and oxygen supports combustion to produce a high-temperature flame. (Other welding methods use inert shielding gases like argon/helium, but the classic pair is O2 + acetylene.)
Final Answer Oxygen and acetylene (oxy-acetylene welding)
