This kind of turning-roll is applicable for narrow gap vessel welding on thick-wall cylinder, or it is necessary to prevent axial drift of work-piece during welding. Its adjustment is adopted with roller up-lift type, which is advanced in structure, complete in function, easy in operation and reliable in performance. So it is ideal equipment for improving welding quality and realizing welding automation.
We also tailor made up your requirements. Please communicate with us for more details. 2. Main Parameters
