Advanced GMAW processes help in welding P91
- By Dan Hernandez and David Benson
- May 26, 2016
- Tube and Pipe Fabrication
- Article
Alloy P91 has excellent high-temperature strength and creep resistance, making it a favored alloy for piping systems for power boilers and other applications that work at elevated temperatures and pressures. The conventional welding processes, gas tungsten arc welding and shielded metal arc welding, do a good job on P91, but modified gas metal arc welding (GMAW) processes and flux-cored arc welding (FCAW) have deposition rates three to four times faster.
Need a filler metal for a 300 series stainless steel?

- Consumables
- Article
Matching a consumable to a 300-series (austenitic) stainless steel is fairly straightforward, but fabricators should be aware that the various options (rod for GTAW, solid or metal-cored wire for GMAW, stick electrode for SMAW, or flux-cored wire for FCAW) have huge productivity differences.
