Welding chrome-moly steel

September 8, 2010 | By Joe Bundy

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 characteristics or welding productivity.
