Name three common welding joint types.

• A. Butt, Fillet, and Corner/T-joint
• B. Corner, Lap, and Bevel
• C. Tee, Lap, and Edge
• D. Butt, Lap, and Seam

Answer: (A)

Joining metal through welding is defined by how the pieces meet at the joint. Three of the most common joint types are butt joints, where the edges sit flush in the same plane and are welded along the seam; fillet joints, where two pieces meet at an angle and a triangular weld fills the corner; and corner or T joints, which cover corners where pieces meet at a right angle or when a piece is welded to the edge of another to form a T. This combination is most frequently used in fabrication for plates and structural members, making it the best answer. Other terms like bevel, edge, or seam refer to weld preparations or different concepts, not the standard set of three common joint types.
