Which finish symbol represents Grinding?

• A. Grinding
• B. Chipping
• C. Machining
• D. Polishing

Answer: (A)

Finish marks in welding diagrams tell you what post-weld work to perform. Grinding as a finish means removing excess weld material and smoothing the surface with an abrasive wheel to achieve a flat, even finish. This is chosen when the goal is a clean, uniform surface without removing a lot of material. The other options describe different post-weld or surface treatments: chipping is slag removal, machining is material removal with machine tools to precise dimensions, and polishing is creating a high-gloss, cosmetic surface. So the symbol indicating the grinding finish is the one that directs the weld finish to be ground.
