When the finish symbol is the letter G, the weld is finished by grinding.

When the finish symbol is the letter G, the weld is finished by grinding.

• A. True
• B. False
• C. Not specified
• D. Both grinding and machining

Answer: (A)

In welding symbols, a finish indication tells you what post-weld operation to perform on the joint. The letter G is the designation for grinding. So if the finish symbol shows G, the weld is finished by grinding after welding to remove excess reinforcement, smooth the surface, and bring the weld contour to the required shape and finish. This method is chosen when you need a smooth, flush surface or to meet surface finish and dimensional tolerances without removing too much material. Machining or filing would be indicated by different symbols, not by the G finish symbol, so the standard interpretation of G is specifically grinding.
