Efficient automatic welding machine for grounding flat iron welding

The utility model discloses an efficient automatic welding machine for grounding flat iron welding. The efficient automatic welding machine comprises a fixing frame, a flat iron pressing assembly, a numerical control moving module, a gas welding gun and a mounting frame. The fixing frame is a frame-shaped frame, clamping grooves parallel to the length-direction side plates are symmetrically formed in the positions, close to one length-direction side plate, of the two side plates in the width direction of the fixing frame and used for installing the flat iron, and the flat iron pressing assembly is arranged in the width direction of the fixing frame and fixed to the inner wall of the other side plate in the length direction of the fixing frame. The numerical control moving module is connected outside the other side of the length direction of the mounting frame; the two gas welding guns are symmetrically arranged up and down and are fixed on the same mounting frame; the mounting rack is driven by the numerical
