What are the four weld types?

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

Answer: (A)

In welding, the basic weld types describe the different ways a bead can join pieces. The four main ones are surface welds, plug welds, groove welds, and fillet welds. A surface weld is laid on the surface to seal or patch a joint. A plug weld joins pieces by welding around or through a drilled hole in one member so the other piece is fused on top. A groove weld fills a groove cut into the edge of the pieces, creating a strong fusion along the joint. A fillet weld forms a triangular bead at the intersection of two pieces that meet at an angle. These cover the common methods used to create welded joints across various situations. Terms like seam or edge refer to specific joint configurations or continuous welds, and arc describes a welding process rather than a weld type.
