Which finish symbol indicates grinding the weld?

• A. Cutting
• B. Grinding
• C. Machining
• D. Finishing

Answer: (B)

Finish symbols on a welding drawing tell you what post-weld work to perform to meet surface quality. The symbol that represents grinding tells you to remove excess weld metal and smooth the weld by grinding, bringing the surface to the required contour without removing base metal. Grinding is chosen when you need a flush, even finish or to reduce weld reinforcement to meet specifications. Other options describe different actions: cutting is pre-weld material removal, machining is a broader post-weld metal-removal process, and finishing is a general term that can include various surface treatments, but the symbol specifically for grinding indicates grinding.
