Seamless steel tube rod welding machine

The seamless steel pipe rod welding machine comprises a machine body shell, a working cavity penetrating through the front surface and the rear surface of the machine body shell is formed in the machine body shell, the top wall of the working cavity communicates with a rotating cavity penetrating through the upper surface of the machine body shell, a rotating block is rotationally arranged in the rotating cavity, and a rotating assembly for driving the rotating block to rotate is arranged in the rotating cavity; a first sliding groove penetrating through the upper surface and the lower surface of the rotating block is formed in the rotating block, and a first sliding rod is slidably arranged in the first sliding groove. The welding module and the polishing module can keep a set distance from the steel pipe pole all the time under the action of a second spring, and the effect of guaranteeing welding and polishing effectiveness is achieved, so that the distance between the welding module and the surface of the
