Which joint type is formed by two pieces meeting at a right angle, creating a T shape?

• A. Butt joint
• B. Lap joint
• C. Tee joint
• D. Corner joint

Answer: (C)

Recognize how weld joints are categorized by how the parts meet. A Tee joint forms when one piece is placed against the side of another at a right angle, so the combined silhouette looks like a letter T. This happens when a plate or bar is joined to the middle of another piece, creating a perpendicular intersection that resembles a T shape. That’s why this type of joint is used for unstiffening or attaching a web or brace to the main piece. In contrast, a butt joint joins pieces end to end in the same plane, a lap joint overlaps one piece over another, and a corner joint brings two pieces together at an exterior corner to form an L shape.
