Which joint is formed by two pieces meeting at roughly a 90-degree angle and welded at the intersection?

• A. Tee Joint
• B. Edge Joint
• C. Lap Joint
• D. Butt Joint

Answer: (A)

When two pieces meet at roughly a 90-degree angle and are welded at the intersection, you’re forming a Tee joint. Imagine one piece standing upright and the other laid across its midsection, creating a T shape. The weld is placed along the intersection where the two pieces touch, tying them together at that cross point. This configuration is distinct from other joints: a straight-end join aligns pieces end-to-end, overlapping pieces create a lap, and joining along edges forms a corner. The defining idea here is the perpendicular crossing with welding at the intersection, which is what creates the Tee joint.
