How many joints can be found in a cruciform weldment?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

In a cruciform weldment the arrangement is a cross made by four arms meeting at the center. The connection is typically achieved with two weld lines: one weld running along the vertical pair of arms and a second weld running along the horizontal pair. These two weld runs create two distinct joints that tie the crossing members together. The arms share the same central intersection, so you don’t count four separate joints at the center; instead, you have two weld joints that connect the members on opposite faces. This is why the number of joints is two.
