Definition

Any fillet or fillet reinforced weld that does not meet the minimum size requirements specified on applicable fabrication documents.

Note: Skewed fillets are exceptionally prone to having undersized weld on sides that have greater than 90° joint fit-up.

Preventive Action

1. Apply weld layers until weld size is met on all sides of joint.

2. Adjust amps/volts.

3. Decrease travel speed.

4. Maintain proper wire stickout.

5. Adjust torch/rod angle.

6. Avoid over grinding.

7. Sequence weld passes so that the toes of

the beads sufficiently overlap one another.

Corrective Action

Apply additional weld passes until the affected

areas are the proper size.
