[0002] In the production process of pressure vessels, the combined welding between the various parts of the saddle is a key step. The saddle is an important component of the pressure vessel and is usually used to support and fix the pressure vessel. Since the pressure vessel will be subjected to a large internal pressure during use, the welding quality of the saddle directly affects the safety and stability of the pressure vessel. In the prior art, the positioning of the saddle during the saddle welding process usually relies on manual operation, which is not only inefficient, but also difficult to ensure the positioning accuracy, which easily leads to problems such as uneven welding and unstable weld quality.
[0003] In addition, the traditional welding positioning method has poor flexibility and is difficult to adjust for saddles of different sizes or shapes. A large number of clamps and positioning devices need to be replaced or adjusted, which not only increases production costs, but also prolongs the adjustment time of the equipment and reduces production efficiency. At the same time, due to the lack of an effective supporting structure, the saddle is easily deformed due to uneven heat during the welding process, which further increases the difficulty and complexity of welding. In view of this, the utility model proposes a welding positioning structure for a finished saddle of a pressure vessel to solve the above problems. Utility Model Content
