Topic overview

A weld repair is a new controlled welding operation in a location that has already experienced a thermal cycle and often contains high residual stress. It must restore function without introducing a greater metallurgical, fatigue or geometric risk.

Before intervention, are technical disposition, complete removal scope, qualified repair procedure, examination and authority approved?

Suitable examination must confirm the original indication is gone before welding.

Every repair adds a thermal cycle, shrinkage and possible property change.
