Which option lists the four basic weld types?

• A. Surfacing, Plug/Slot, Fillet, Groove
• B. Butt weld, Fillet, Groove, Plug/Slot
• C. Surfacing, Fillet, Butt weld, Arc weld
• D. Lap weld, Fillet, Groove, Plug/Slot

Answer: (A)

The main concept is how metal can be joined or built up in common welding practice. The four basic weld types are fillet welds, groove welds, plug/slot welds, and surfacing welds. Fillet welds form a triangular bead in a corner, edge, or T-joint without needing a groove. Groove welds require a prepared groove in one or both pieces and are filled with weld metal to create a strong joint, typically used on thicker sections. Plug or slot welds pass through a hole or slot in one plate to connect it to another plate, providing a solid connection in overlapping or joined plates. Surfacing welds deposit weld metal on the surface of the base metal to build up material, restore wear, or improve surface properties without tying two pieces together at a seam. These four represent the main ways material is joined or enhanced in many welding tasks, which is why they’re listed as the basic types.
