Welding rotator as the main welding auxiliary machinery equipment, widely used in petrochemical, pressure vessel, piping, metal structure, boiler and other industries, is the necessary technical equipment for barrel circular seam welding and inwall bead welding. Its efficient and convenient for users to create more opportunities; its easy operation, flexible and reliable greatly reduce labor intensity for manufacturers to create infinite vitality.The rotator series which is product by our company have two types: adjustable and self-adjusting, used for welding, polishing, plastic lining and assembly of cylindrical barrel.

The rotator is through the friction between weldment and spindle roller to drive the cylindrical weldment to rotate; its rotation speed within a certain range can be variable speed.Sel-adjusting rotator is according to different diameter of workpieces,relying on the weight of workpiece itself, roller center rotates around support center with a different angle to achieve self-adjust.to meet the requirement of a range of workpiece size, achieve stable support, safe operation.Self-adjusting rotator through manual adjust the center distance between two rollers, can meet the requirement of a wide range of workpiecesize to achieve a stable support.
