Tube and Pipe Fabrication

The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

Advanced GMAW processes help in welding P91

May 26, 2016 | By Dan Hernandez, David Benson

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.
