Welding chrome-moly steel - The FABRICATOR

Welding chrome-moly tube and pipe conventionally is done with shielded metal arc welding (SMAW) or submerged arc welding (SAW).Flux-cored arc welding (FCAW) has been tried,but the wires had some drawbacks that prevented widespread acceptance.Recent developments have reduced some of these disadvantages,so GMAW deserves a fresh look.The switch might lead to improvements in the weld's Welding Procedure Specifications (WPSs) - National BackgroundThe new NCPWB Welding Procedure Specification numbering system clearly defines the type of metals to be welded,the welding process used and allows for identification of variations in a process.This numbering system will be used on all Welding Procedure Specifications revised or developed in the future.The following describes the new numbering system:Welding ProcedureWelding Procedure Specifications (WPSs) - National BackgroundThe new NCPWB Welding Procedure Specification numbering system clearly defines the type of metals to be welded,the welding process used and allows for identification of variations in a process.This numbering system will be used on all Welding Procedure Specifications revised or developed in the future.The following describes the new numbering system:Welding Procedure
