Thermal beveling of pipe in preparation for welding requires the use of which tool?

• A. Electric grinder
• B. Plasma cutter
• C. Oxyfuel Torch
• D. Arc welder

Answer: (C)

Beveling the pipe end for welding relies on shaping the edge so the weld can penetrate properly. When you need to create that bevel with heat, an oxyfuel torch is the best tool because its flame can be precisely controlled to heat and melt the edge, allowing you to form a clean, consistent bevel along the pipe’s end.

Electric grinders are for removing material and finishing surfaces, not for forming a bevel with controlled heating. Plasma cutters can bevel edges but are typically hotter and more abrupt, which can be harder to control for a smooth weld prep. An arc welder is a welding device, not a shaping or cutting tool, so it doesn’t perform the beveling itself.
