For fabrications where the need for a welded repair has been identified, but for which a Post-WeldHeat Treatment (PWHT) would be impractical or expensive, it is possible to affect a repair by using aprocedure which is intended to give rise to significant refinement and tempering of the Heat-AffectedZone (HAZ) microstructure. Various approaches to such repair, in terms of selection of weldingparameters, welding process and consumables, have been explored by numerous organizations overseveral decades. Published investigations and the provision for controlled deposition repair in variousstandards are considered in this review.
