What describes an edge joint when the surfaces are in contact and edges flush?

• A. Edge joint
• B. Lap joint
• C. Butt joint
• D. Fillet joint

Answer: (A)

Edge-to-edge alignment where the flat surfaces touch along a straight seam and the edges are flush describes an edge joint. There’s no overlapping material—the weld runs along the interface where the two faces meet. This is different from a lap joint, where one piece overlaps the other and thickness increases at the seam; a butt joint, where pieces end-to-end in the same plane and welds form along that end-to-end seam; and a fillet joint, which is a weld in a corner formed by two members meeting at an angle. So, the description fits an edge joint.
