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.

8 FAQs about orbital FCAW

August 8, 2007 | By John Emmerson

Mechanized pipe GTAW was first introduced about 50 years ago for nuclear power plants, and then for steam-generation components and process piping. Orbital FCAW was developed to overcome the limitations of orbital GTAW for large-diameter, heavy-wall pipe. With orbital FCAW, deposition rates of 8 lbs./hr. are achievable. Just as a power saw is a tool for a carpenter, orbital welding systems are a productivity tool for the welder that empower him or her to weld faster and more accurately.
