The system is mainly used for welding elbow to flange. It requests
less labor intensity and skills than manual welding, but gets high
The system sloves the issue of automatic welding for both inside
and outside seams in welding elbow to flange with MAG welding
procedure. In welding, the welding pool is in protection gas to
insure quality and meet requirement of welding joints.
Solved inside and outside two seams welding simultaneously,
minimizingrequirements on labor intensity and skills; Open headstock rotator design which is convenient for load/unload; High efficiency, e.g φ155 pipe welding time less than 60s for two
seams at the same time; Unique welding process for two seams; Patent design of open headstock rotator with AC servo motor for
stable rotation and high a accurate control; Suitable for variable OD bent pipe – flange inside and outside
seams welding simultaneously.
