Name three common weld joint configurations used in wire feed welding and briefly describe each.

• A. Butt joint: Edges butt together; Fillet joint: L-shaped weld between two pieces; Lap joint: Overlapping pieces welded along a seam
• B. Butt joint refers to pieces overlapped and welded along a seam; Fillet joint is formed by welding two pieces edge-to-edge; Lap joint is not commonly used
• C. Fillet joint is used for butt edges; Lap joint is two pieces welded end-to-end; Butt joint is an L-shaped weld
• D. Lap joint is a butt weld; Butt joint is a fillet weld; Fillet joint is a Lap weld

Answer: (C)

Three common weld joint configurations in wire feed welding are butt joints, fillet joints, and lap joints. A butt joint brings the edges of two pieces together in the same plane and welds along that seam, so the weld fuses the edges where the pieces meet. A fillet joint has the two pieces meeting at a corner or along an edge, and the weld fills a triangular area between them, creating a visible fillet between the parts. A lap joint stacks one piece over the other and welds along the overlapped seam, increasing thickness and providing access for welding from one or both sides. These descriptions show how the weld bead is positioned relative to the joined pieces and help determine penetration, strength, and welding accessibility.
