What tool is used to buff the beveled edges during pipe end preparation?

• A. Power-driven wire brush
• B. Hammer
• C. Grinder
• D. Chisel

Answer: (A)

Preparing a pipe end for welding requires removing burrs, scale, and oxidation from the bevel to ensure a clean, uniform weld root. A power-driven wire brush is ideal for this task because its bristles quickly scrub away burrs and surface contaminants without removing too much material, leaving a smooth, clean bevel that welds can fuse to properly. The other tools don’t fit this finishing role: a hammer can deform the edge; a grinder is used for heavier material removal or beveling but risks altering the bevel or over-cutting; a chisel is for cutting and edging, not finishing beveled pipes.
