Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a welding process for automatic welding equipment for high-pressure vessels. Background technique [0002] When performing submerged arc welding on spherical workpieces such as high-pressure vessels, small workpieces are usually welded by manual flipping. During the flipping process, the quality of manual welding cannot be guaranteed, and it is a waste of time. More importantly, For large workpieces, turning them manually is time-consuming, laborious, and unsafe. At present, some enterprises use truss trucks to lift workpieces for processing. This method is extremely inconvenient to operate, has low automation, and low welding efficiency and welding quality. Therefore, it is necessary to design a welding process for spherical workpieces of high-pressure vessels and other equipment, improve the welding efficiency and welding quality of spherical workpieces of high-pre...
