Background technique

The high-pressure gas storage tank is a common pressure vessel. The tank body is usually welded by arc welding to the two parts of the tank body, and the quality of the welding seam is extremely high, especially the circumferential direction. The thickness and uniformity of the welding seam need to be strictly controlled.

Since the two-part shell of the tank part needs to be spot welded before linear welding, there will be a certain shape and position error during the spot welding process, and there will also be a positioning error during the positioning process. Due to individual differences in the process, the position of the weld will be offset to a certain extent, and it is difficult to ensure the consistency of the quality of the weld during welding. The welded parts are inconvenient for loading and unloading in the process of loading and unloading, and manual intervention is required, so a lot of loading and unloading time will be wasted and the production rhythm will be affected. After long-term use, the protective sleeve in the welding torch head of the multi-axis welding robot will become too hot, which will easily cause deformation or accelerate the aging of the material, which not only affects the service life of the welding torch head, but also affects the stability of the welding quality.
