A staggered intermittent fillet weld has arrow side significance.

A staggered intermittent fillet weld has arrow side significance.

• A. True.
• B. False.
• C. Sometimes.
• D. Not specified.

Answer: (B)

Arrow side significance is about which side of the joint the weld size shown on the symbol applies to. For a simple continuous fillet weld, the size specified can be read as applying to the weld on the arrowed side. In a staggered intermittent fillet weld, however, you have separate welds placed on alternating faces along the joint, each with its own length and spacing (pitch). There isn’t a single continuous bead whose size would be read from the arrow side for the entire joint. Because the welds are distributed and alternate sides, the concept of a single “arrow side” rule doesn’t apply. So saying that a staggered intermittent fillet weld has arrow side significance isn’t correct. If a pattern uses the same per-weld dimensions, those are provided for each weld or by the pattern notes, not by a single arrow-side interpretation.
