High-efficiency steel beam welding process and equipment

The efficient steel beam welding technology comprises a cross beam, a vertical beam is fixedly arranged on one side of the cross beam, a sliding seat is fixedly arranged at the end, away from the cross beam, of the vertical beam, a sliding rail is arranged on one side of the sliding seat, and the sliding seat is slidably connected with the sliding rail; the two ends of the cross beam are each fixedly provided with a sliding groove, each sliding groove is provided with a sliding block in a sliding mode, and each sliding block is fixedly provided with a welding gun. In the welding process of a piece of I-shaped steel, only one-time clamping and one-time positioning are needed, only the I-shaped steel needs to be turned over in the subsequent welding process, it is guaranteed that a to-be-welded part faces a welding gun, the cumbersome step of repeated clamping and repeated positioning is omitted, and the problem of weld joint position deviation caused by errors generated in multiple times of positioning is also
