What is the correct AWS term to describe the fuel gas and oxygen cutting process?

• A. Oxyfuel gas cutting
• B. Flame cutting
• C. Burning
• D. Flame burning

Answer: (A)

Oxyfuel gas cutting is the AWS term for this process. It names the method that uses a fuel gas (like acetylene or propane) mixed with oxygen to preheat and then oxidize the metal to cut it, with a high-velocity oxygen jet blowing the molten oxide away. The word “oxyfuel” highlights the two gases involved, and “gas cutting” specifies that the metal is removed by oxidation rather than by piercing or burning in a general sense. While people might say flame cutting in casual speech, AWS uses oxyfuel gas cutting as the precise process name. Burning or flame burning describe the chemical reaction occurring on the surface, not the official process name.
