Anotácia textu normy ASME STP-PT-058:2013 :
For fabrications where the need for a welded repair has been identified, but for which a Post-Weld Heat Treatment (PWHT) would be impractical or expensive, it is possible to affect a repair by using a procedure which is intended to give rise to significant refinement and tempering of the Heat-Affected Zone (HAZ) microstructure. Various approaches to such repair, in terms of selection of welding parameters, welding process and consumables, have been explored by numerous organizations over several decades. Published investigations and the provision for controlled deposition repair in various standards are considered in this review.
