[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. This application uses a lifting electric telescopic rod to drive the plasma welding head close to the steel pipe, and cooperates with the airflow when extracting the air inside the pneumatic shell to drive the plasma welding head to rotate, so as to achieve the annular welding of the steel pipe. The spring is adjusted as the dynamic activity, and the steel pipes of different shapes can be dynamically welded.

Use the pressure-guided method, cooperate with the expansion and contraction of the adjustment spring, and use the airflow when extracting the air inside the pneumatic shell to drive the rotating ring to rotate and perform annular welding on the steel pipe. During welding, according to the different shapes of the steel pipe, the adjustment spring is expanded and contracted as the dynamic activity between the lifting plate and the adjustment plate to achieve welding of steel pipes of different shapes; 3. Using mechanical guidance, the vacuum suction cup drives the universal head to swing on the driving seat to fit steel pipes of different shapes, and at the same time drives the guide column to move in the guide seat. Using airflow guidance, the air pump inputs high-pressure airflow into the guide seat, and blows it out through the guide seat, the driving seat and the vacuum suction cup to clean the side wall of the steel pipe. When the driving seat touches the contact switch, it indicates that the vacuum suction cup fits the steel pipe, and the air pump does not input high-pressure airflow into the guide seat. Then the air pump draws vacuum from the guide seat, the driving seat and the vacuum suction cup. 4. By using the method of extracting vacuum to generate pressure difference, when the vacuum suction cup is adsorbed to the side wall of the steel pipe, the guide seat, the driving seat and the vacuum suction cup are in a vacuum state. At this time, the external air pressure pushes the air guide plate to move. By using the slope guidance method, the push block pushes the driving block and the clamping seat to move, thereby achieving the fixation of the universal head, determining the swing angle of the vacuum suction cup and the universal head, and avoiding the universal head from swinging during the welding process and causing position changes; 5. The pressure difference generated by extracting vacuum can also drive the first fixed seat to move, and then drive the fixed guide rod to move, fix the guide column, and determine the position of the guide rod in the guide seat to avoid the guide rod pushing the steel pipe to move during welding, resulting in the center points of the steel pipes on both sides cannot be coaxially set.
