Automated PU Roller Pipe Welding Rotator / 5 Ton Welding Turning Rolls
1. Main introduction
Welding rotator is a kind of our advanced welding equipment, which is be researched and manufactured absorbing domestic and international advanced equipment. It is mainly used for pipe, containers, boilers, pressure vessels, oil tank and other cylinder’s assembling, burnishing and welding, can use together with column and boom and SAW system to realize inside and outside girth and longitudinal welding. Its series includes self aligning rotators (SAR), and conventional rotators (WR). Accordingly this device has advantages of compact structure, small cubage, beautiful shape, lightweight, convenient operating and so on. The machine can assort all kinds of auto welding or manual welding, improving welding quality, lessening welding labor and improve productivity.
