When the driving motor 306 is working, the conical positioning head 302 on the right drives the pipe 400 and the conical positioning head 302 on the left to rotate automatically, thereby achieving full laser cladding welding of the outer wall of the pipe 400; when the adjusting motor 504 is working, the adjusting screw 505 drives the laser cladding welding gun heads on the two connecting seats 503 to move inward at the same time, thereby improving the laser cladding welding efficiency of the pipe 400; when the working time of the adjusting motor 504 reaches the preset time, the adjusting motor 504 stops working, and the output shafts of the two linear electric cylinders 603 slowly extend; when the two linear electric cylinders 603 When the output shaft contacts the left side of the movable support block 201, the first control button 601 is in a pressed state. At this time, the laser cladding welding gun head on the left stops working. When the output shafts of the two linear electric cylinders 603 push the movable support block 201 to move slowly to the right, the laser cladding welding gun head on the right performs automatic laser cladding welding on the remaining part, so as to avoid the airflow in the two laser cladding welding gun heads affecting the contact between the metal powder and the pipeline 400, thereby improving the laser cladding welding accuracy at the joint; when the control extrusion plate 604 presses the second control button 602, the laser cladding welding gun head on the right stops working, thereby improving the laser cladding welding quality at the joint while ensuring the welding efficiency; After the pipe 400 is processed, the staff presses the U-shaped frame 702 again by controlling the handle 707. At this time, the two ratchet mechanisms 704 drive the multi-function frame 703 to rotate half a circle; the two dial indicators 706 are made to contact with the processed pipe 400, and the staff turns on the drive motor 306 to realize automatic detection of the processed pipe, so that the staff can know the laser cladding welding accuracy of the pipe 400 through the fluctuation of the needles on the two dial indicators 706; when the two switching brackets 502 drive the two ratchet mechanisms 704 to rotate, the multi-function frame 703 can automatically squeeze the four circular stabilizing bars 802 to move outward, and when the multi-function frame 703 rotates to the appropriate position under the action of the two switching brackets 502 and the two ratchet mechanisms 704, the four circular stabilizing bars 802 are inserted into the four arc-shaped stabilizing grooves 7031 again under the action of the four support springs 804.
