Selection, development and refinement of repair and shaft finishing weld procedures meeting ABS and Navy standards for high strength alloy and carbon steel propulsion shafts are ongoing activities of Shaft Repair Facilities (SRFs). For example, processes such as Electroslag Surface Cladding (ESSC) and Reciprocating Wire Feed (RWF) for Alloy 625 cladding have been explored. Alternatively, novel applications of mechanized Gas Metal Arc (Mech GMAW) were developed to produce weld surfacing and inlay filling procedures balanced for productivity and first-time quality. Case studies and lessons learned are described.
