Intermittent stiffener weld callout

Intermittent fillet welds use separated weld segments rather than one continuous bead. The length value gives each segment, while pitch gives the repeat spacing. Placing the same notation on both sides of the reference line communicates matching welds on the two sides of a web stiffener. The callout is useful when the fabrication specification requires a controlled weld pattern. Before using the layout in a build or document, compare every label with the source requirements and update the drawing when parts, conditions, or materials change. The example is deliberately small so the essential relationships remain readable, easy to review with collaborators, and ready to extend with the details required for the actual project.

FAQ

Questions fréquentes

What is an intermittent weld?

It is a series of separated weld segments along a joint.

What is pitch?

Pitch is the center-to-center distance between intermittent weld segments.

Why show both sides?

It specifies a weld on each side of the joint.
