Then, the clamping bolts are rotated to clamp the opposite ends of the clamping bolts on the outside of the pipe. Next, the pneumatic telescopic rod is activated to extend, causing the reduction motor to move down. At this time, the extrusion power wheel at the output end of the reduction motor makes rolling contact with the outside of the pipe, and the support rod moves down as the pneumatic telescopic rod extends, causing the positioning bearing to fit against the outside of the pipe. Then, the reduction motor is activated to drive the extrusion power wheel to rotate, and drive the pipe to rotate. At this time, the electric telescopic rod is activated to cause the welding head to extend. After manual adjustment, the gap of the pipe is gradually welded. After the welding is completed, the hydraulic telescopic rod is extended to cause the installation recess and the hollow frame to be lifted, and the grinding motor is lifted.

The overall operation is convenient and it is convenient to weld pipes of different lengths.

[0012] The exhaust fan, when activated during welding, draws air downwards from the bottom of the perforated frame. As the airflow passes through the frame, the smoke and dust are filtered by the filter plate, which traps some of the smoke and dust, allowing the gas to pass through while simultaneously blocking it. This, combined with the exhaust fan's downward motion, ensures stable visibility for the welder, indirectly improving welding quality and reducing the impact of smoke and dust on the workers.
