[0025] During operation, when the existing steel structure welding positioning device is in use, it is unable to adjust the angle of the steel structure, resulting in limitations in welding operations. Moreover, for some large-scale steel components, effective positioning cannot be achieved. In this application, the auxiliary positioning device is used.

With the cooperation of the sliding groove 409 and the sliding block 411, the positioning plate 3 rotates.
