Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a device for welding the outer longitudinal seam of a cylinder. Background Art

[0002] The outer longitudinal seams of helium cylinders need to be welded to ensure the sealing and structural integrity of the cylinders. Welding can effectively connect the various parts of the cylinders to prevent helium leakage, while enhancing the structural strength of the cylinders so that they can withstand the pressure of high-pressure gas. Therefore, welding is a key step in the manufacturing process of helium cylinders. Appropriate processes and parameters must be used and strictly inspected to ensure the safety and reliability of the cylinders.

[0003] The utility model with the authorization publication number CN212977085U provides a plasma automatic welding system device for the outer longitudinal seam of a cylinder, which belongs to the technical field of "welding" and the protected claim: "It includes a base, a plasma welding gun and a roller, the left side of the base is slidably connected to a lifting block, the upper left end of the lifting block is fixedly connected to a connecting rod, the lower left end of the lifting block is rotatably connected to a first threaded rod, the left end of the connecting rod is fixedly connected to a fixed block, the left end of the fixed block is fixedly connected to a first motor, the left side of the connecting rod is slidably connected to a moving block, the inner side of the moving block is slidably connected to a sliding rod, and the lower end of the sliding rod is fixedly connected to a plasma welding gun.
