Which finish symbol indicates the weld should be machined after welding?

• A. M
• B. C
• C. G
• D. O

Answer: (A)

Post-weld finish symbols tell you what happens to the weld surface after welding. The symbol that stands for a machined finish instructs you to machine the weld after welding. Machining removes excess weld metal, flattens and true-ups the surface, and helps meet the required tolerances and surface quality. The other finish symbols point to different post-weld processes (like grinding or other finishes) and do not indicate machining. So the machined finish symbol is the one that means the weld should be machined after welding.
