Description
Technical Field
[0001] The utility model relates to the technical field of welding auxiliary devices, in particular to a welding training fixture. Background Art
[0002] The dangerous nature of welding work places high demands on the personal skills of welders, especially in the production process of special equipment such as pressure vessels. The skill level of welders directly affects the quality and operation safety of the equipment. The growth of a welder must be completed through a lot of professional training. Improper operation can easily lead to safety accidents. In welding training, simple flat welding can be carried out on a flat ground. The welding operation space is large and the technical difficulty is relatively low. However, horizontal welding, overhead welding and 45° angle butt welding of pipes in welding training are often seen in actual operations. This kind of welding at special angles and positions cannot stably fix the welding base material to be welded. Therefore, welding training must be carried out with the help of professional tooling. However, there are very few types of existing welding tooling, which cannot be applied to a variety of environments, cannot accurately adjust the angle, and cannot meet the needs of welding training.
