One to-be-welded steel claw head 21 is welded continuously, the welding robot 2 automatically welds the next to-be-welded steel claw head 21, after the whole to-be-maintained anode steel claw 16 is welded with the to-be-welded steel claw head 21, the welding robot 2 returns to the position, and waits for the next to-be-maintained anode steel claw 16 to be welded, two welding stations circulate in sequence, and a set of feeding robot 17 is shared.

It should be noted that, based on the control logic disclosed above, it is naturally possible for a person skilled in the art to obtain a control system for realizing an automated operation of the welding repair system.

The present utility model enables maintenance of the anode steel stud 16 by providing a structure of the stud welding maintenance system.

Although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
