Which option lists all four weld types correctly?

• A. Surface, Plug, Groove, Fillet
• B. Surface, Plug, Arc, Fillet
• C. Plug, Groove, Fillet, Edge
• D. Surface, Groove, Lap, Fillet

Answer: (A)

Weld types refer to the basic shapes of welds used to join parts, not the welding process or the way parts are arranged. The four standard weld types you should know are surface weld, plug weld, groove weld, and fillet weld. The option that lists all four is the one that includes Surface, Plug, Groove, Fillet. A surface weld deposits material on a surface to build up or cap a layer; a plug weld welds through a hole to join one piece to another; a groove weld fills a groove cut into the joint edges to create the bond; and a fillet weld forms a triangular bead at the intersection of two surfaces. The other options include terms that are processes (like Arc) or joint configurations (like Edge or Lap) rather than the four basic weld types, so they don’t list all four weld types together.
