The self-aligning Welding Rotator is a kind of positioner which uses the friction between the active roller and the weldment to drive the workpiece to rotate. The swing angle of the wheel set can be adjusted automatically according to the diameter of the workpiece, and the center can be adjusted automatically. It is mainly used for assembling or welding cylindrical workpieces such as pipes, vessels, boilers, oil tanks, etc. when it is matched with welding machine and welding power supply, it can realize the welding of inner and outer longitudinal seams and inner and outer circumferential seams of workpieces.
The Conventional Welding Rotator is composed of an active and a passive one. The driving roller is driven by two motors respectively. Through the speed regulating motor, the speed controller realizes the stepless speed change through frequency conversion speed regulation or electromagnetic speed regulation. The linear speed of workpiece rotation is 6-60m / h, which can meet the needs of manual welding, automatic surfacing welding, automatic submerged arc welding and other welding needs, as well as various riveting of the workpiece. The distance between rollers can be adjusted by screw rod or screw grading to meet the welding requirements of different specifications of workpieces.
Self-alining welding rotator and Conventional Welding Rotator can be all use for Pipe, Pressure Vessel, Tank , Wind tower production.
