Which joint type is formed by joining two pieces at a corner, sometimes described as a corner or T-joint?

• A. Butt/T-joint
• B. Corners only
• C. Tee joint
• D. Corner/T-joint

Answer: (D)

Understanding how pieces meet is key. When two pieces join at a corner, creating an intersection you’d see on an edge of a frame or box, that connection is classified as a corner joint. In many welding references, that same configuration is grouped under a term like “Corner/T-joint” to cover both corner-style and T-shaped variations of the intersection. So this description fits: two pieces meeting at a corner can be labeled a corner/T-joint because the weld completes the corner where the pieces meet, and the arrangement can resemble a T from another perspective. A tee joint, by contrast, is specifically when one piece joins to the face of another perpendicularly along its midsection, forming a T shape, not merely a corner. A butt joint implies ends that butt against each other in the same plane, not corners. “Corners only” isn’t a standard joint name. The corner/T-joint label best captures the scenario of two pieces meeting at a corner.
