The possible injuries to human body caused by welding include burn, electric shock, visual impairment, toxic gas inhalation, over-irradiation of ultraviolet rays, etc.

At present, in the welding operation aiming at the non-radial pipe joint product, a saddle-shaped track is formed in the welding process. The saddle-shaped welding is manually operated, the quality cannot be guaranteed, the production efficiency is low, and the production cost is high. The existing saddle-shaped cutting equipment does not have the change of the attitude angle of a welding gun, and cannot solve the flow phenomenon of a welding seam molten pool during cutting, so that the realization cannot be realized. In addition, in the welding process of the high adapter tube, due to the large size, a large distance is needed for the longitudinal movement of the welding gun, and in the prior art, one lifting shaft of the cross sliding frame is directly arranged on the cross beam. In the welding operation suitable for the high connecting pipe, the lifting shaft needs to be long enough, however, a new technical problem is brought about in that when the highest point is welded, the lifting shaft is higher than the cross beam part too much, so that the gravity center of the lifting shaft is too high, and the situation that the gravity center is unstable due to too large distance from the cross beam to the supporting point of the lifting shaft is generated, so that the welding accuracy of a welding gun below is further influenced.

In view of this, the present invention is especially provided.
