Welding rotator is welding auxiliary equipment, specifically a welding turning rolls, commonly used in cylinder work piece outer circumferential and longitudinal seam welded both inside and outside. Consists of Base, driving wheel, driven wheel, frame, transmission device, power-driven device and so on. Gear driven active wheel, active wheel and cylinder friction between the work piece drives the work piece rotation to achieve modification, achieving inner and outer of girth and horizontal position of the longitudinal seam weld, supporting automatic welding machine for automatic welding can be realized, can greatly improve the weld quality and reduce labor intensity and improve work efficiency. Welding rollers can be used with manual welding as testing and assembly of cylinder work piece.
