8 FAQs about orbital FCAW: Maximizing a productivity tool for large pipe weldingMechanized 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.

Virtually welding: Training in a virtual environment gives welding students a leg upToday several companies offer technologies that help beginning welders get that hand motion just right. None claims that the technology will replace the real thing, of course, but they do say that training in the virtual world can give students a significant leg up by the time they weld for the first time. It helps teach students what really happens between the welding arc and workpiece, why certain hand motions produce good beads while other motions don't. And it also may help introduce welding to students who wouldn't have given the trade a second thought.
