Weld Repair

The engineering process of restoring the integrity of a defective or degraded weld through approved repair methods.

Definition

Weld Repair is the controlled engineering process of removing, correcting and rewelding defective, damaged or degraded welds to restore their structural integrity and compliance with applicable engineering codes, standards and quality requirements. Weld Repairs are performed using qualified welding procedures and are typically verified through inspection and non-destructive testing before acceptance.

Why It Matters

Weld Repairs restore the integrity of defective or degraded welds using approved repair procedures and qualified welding practices.

In Practice

Weld Repairs are typically performed in accordance with qualified Welding Procedure Specifications and applicable construction or in-service repair codes, with subsequent inspection confirming the acceptability of the completed repair.

Common Misuse

A Weld Repair is the activity of restoring a defective weld, whereas a Welding Procedure Specification defines the approved welding method used to perform that repair.
