[0002] As an auxiliary configuration for the passive safety of the vehicle body, airbags are increasingly gaining attention. If a vehicle collides, the airbag inflation system can quickly inflate it in less than one tenth of a second. When the airbag expands rapidly, it will rush out from the steering wheel, dashboard or seat side, thereby protecting the occupants from the impact of the collision.

[0003] During the installation of the airbag, in order to prevent it from being scratched and damaged by internal parts, it is usually placed in the airbag bracket. In order to improve the protection of the airbag, the various parts of the airbag bracket are usually connected by welding. During the welding process, in order to prevent the parts from shifting, the bracket is placed in a fixture before welding. However, after welding, the surface temperature of the bracket is too high due to the action of the welding head, which makes it inconvenient to remove the bracket and there is a certain risk.
