Pressure Vessel Welding Manipulator, also known as a welding column and boom, is a high-automated auxiliary equipment essential for the welding industry. By utilizing column rotation and boom retraction/lifting, it precisely meets the welding requirements of cylinders across various sizes.
The welding head is securely fixed at one end of the boom to facilitate automatic welding. This versatile system can be integrated with welding rotators or tank turning rollers to perform high-quality internal and external longitudinal and circumferential seam welding. It is extensively applied in Boiler, Petrochemical, Shipbuilding, and Steel Structure industries.
