Skewed joints can apply to which type of joints?

• A. T and corner joints
• B. Butt joints
• C. Lap joints
• D. Fillet joints

Answer: (A)

Skewed joints occur when the pieces meet in a way that the weld axis isn’t in a simple, straight line relative to the joint faces. This happens most clearly with tee and corner joints, where a piece attaches to the face or edge of another member, creating an intersection that isn’t coplanar. The weld must bridge across edges that aren’t in one flat plane, so the bead tends to run at an angle to the joint surfaces and from multiple planes.

In contrast, butt joints involve two pieces lying in the same plane with aligned edges, lap joints overlap along a straight line, and fillet joints form a triangular weld at a corner where the pieces meet at a predictable angle. Those configurations don’t inherently produce the skewed geometry seen in tee and corner joints, where the joint geometry forces the weld path to be angled.
