Welding slag discharging and spot welding equipment for metal machining

The utility model discloses welding slag discharge spot welding equipment for metal processing, which comprises a machine base, a supporting block is fixedly mounted on the left side of the machine base, a welding device is fixedly mounted on the right side of the machine base, and a driving device is fixedly mounted in an inner cavity of the supporting block. The right side of the driving device penetrates through the supporting block and extends to the outer portion of the supporting block. According to the welding slag discharging spot welding equipment for metal machining, a half protruding block on a rotary disc drives a supporting frame to move left and right, a protruding extending block and a rolling wheel drive a slag removing strip to move up and down, the slag removing strip can cover a plate after moving upwards, and then the slag removing strip can move in situ to scrape welding slag from the plate; the electric welding equipment can automatically and effectively treat welding slag left on a plat
