While the rotating disc 0204 rotates, the rotary clamper 0503 rotates clockwise along with the rotating disc 0204 under the linkage rotation of the supporting shaft 0203B and the support of the rotary support connecting bracket 0504. In order to enable the normal line of the welded elliptical oblique section formed after laser cutting and the welding rotation central axis to be located in the same vertical plane, when the angle adjusting rotating hand wheel 0103 is rotated, the power transmission driving spur gear 0303 fixed on the angle adjusting rotating hand wheel 0103 drives the rotation center adjusting ellipse 0301 to rotate anticlockwise and drags the sliding bottom plate 0102 to move forwards, so that the normal line of the welded elliptical oblique section is far away from the vertical plane where the welding rotation central axis is located, and therefore the backward movement of the normal line of the welded elliptical oblique section caused by the operation that the elliptical oblique sections of the subsequent welded circular tube 0214 are completely overlapped is compensated, and the angle of the welding rotation can be displayed through the angle change dial 1013 engraved on the rotation center adjusting ellipse 0301 and the angle change dial 1014 located above the angle change dial 1013. In linkage with the angle adjustment rotating hand wheel 0103, the angle adjustment cam 0717 rotates, the angle compensation long axis dial indicator 1006 rotates corresponding to the welding angle to determine the rotating position of the angle adjustment cam 0717, and the long axis generating block 0911B tightly attached to the angle adjustment cam 0717 moves up and down in the generator outer frame 0911A along with the rotation of the angle adjustment cam 0717. Under the rotation regulation of the angle regulation rotating hand wheel 0103, after the rotation of the welding angle is completed, the laser head is moved back to the original position, the butt joint advancing hand wheel 0210 is rotated, the clamping moving device 0205 drives the welding circular tube 0214 to move on the butt joint lead screw 0206 until the automatic limiting telescopic rod 0213 completely extends into the automatic limiting telescopic tube 0211 again, the elliptical oblique sections of the welding circular tube 0214, which are aligned and fixed with the automatic limiting telescopic tube 0211 at two sides, are completely overlapped, the normal line of the welding elliptical oblique section moves backwards, the normal line of the welding elliptical oblique section and the welding rotating central shaft are located in the same longitudinal vertical plane, and the center of the welding elliptical oblique section and the laser head are located on the same vertical line in the symmetrical plane of the device. In addition, the rotary fixing handle 0510 is rotated to form clamping connection between the rotary clamping device 0503 and the rotary connecting hole 0507A, so that the rotary clamping device 0503 cannot rotate, the rotary hand wheel 0556 is locked by rotating and telescoping, the front and rear telescopic cylinders 0507B and the left and right telescopic cylinders 0508B clamp the follow-up telescopic rod 0511, the rotary clamping device 0503 cannot move, and the position of the rotary clamping device 0503 is determined; the support adjusting handle 0506 is rotated to draw out the rotation support screw shaft 0505 from the hole of the rotation support connecting bracket 0504 and completely extend into the threaded hole of the support shaft 0203B. Subsequently, the adjusting rocker 0407 is rotated to move the double adjusting rod 0404 up and down, so that the rotating center up-down adjusting scale pointer 1002 is located at the scale mark corresponding to the radius of the welding round tube 0214, and the welding rotating center axis coincides with the normal of the welding elliptic oblique section. In linkage with the rotation of the adjusting rocking post 0407, the size adjusting moving block 0718 pushes the angle adjusting cam 0717 to move along the adjusting cam supporting shaft 0714, the size compensation long-axis scale pointer 1008 points to the graduation line corresponding to the radius of the welding circular tube 0214 to determine the moving position of the angle adjusting cam 0717, the long-axis generating block 0911B tightly attached to the angle adjusting cam 0717 moves along with the angle adjusting cam 0717 to move up and down in the generator outer frame 0911A, the rotating position determined by the rotation of the angle adjusting cam 0717 along with the angle adjusting rotating hand wheel 0103 is combined, so that the position of the long-axis generating block 0911B in the generator outer frame 0911A is determined, and at the moment, the long-axis fixing bolt 0925 is screwed into the long-axis generating block 0911B to determine the position of the long-axis generating block 0911B. Further, as the adjustment rocker 0407 rotates, the short axis determination lead screw 0911E rotates, that is, the short axis generation block 0911C moves in the generator outer frame 0911A, and the size compensation short axis scale pointer 1010 points to the graduation mark corresponding to the radius of the welded round tube 0214, so as to determine the position of the short axis generation block 0911C in the generator outer frame 0911A. Subsequently, the lifting adjusting hand wheel 0525 is rotated to enable the front and rear telescopic devices 0507, the left and right telescopic devices 0508, the follow-up telescopic rod 0511 and related components to move downwards along the lifting screw shaft 0513 to the position where the pointer 1004 clamping the lifting adjusting scale points to the scale mark corresponding to the radius of the welded circular pipe 0214, at the moment, the rotary clamping device 0503 moves to the position of the welded circular pipe 0214, the rotary clamping handle 0503E is rotated to clamp the welded circular pipe 0214, and after the welded circular pipe 0214 is clamped, the clamping handle 0205E is rotated and moved to enable the clamping moving device 0205 to loosen the welded circular pipe 0214. The rotating disengagement adjustment rocking post 0526 makes the welding circular tube 0214 far away from the clamping moving device 0205 to prevent the structure interference, at this moment, the rotating motor 0608 drives the welding circular tube 0214 and the connected components to rotate, and the circular welding of the welding circular tube 0214 is completed.

Because the welding circular tube 0214 size is different, the welding rotation angle is different, and the major axis and the minor axis of the welding edge ellipse of the welding circular tube 0214 oblique cross-section are different, namely during spin welding, under the fixed condition of laser head, the distance of ellipse edge welding point to the laser head changes along with the rotation during spin welding, has changed the distance between each welding point and the laser focus position to make the laser energy that each welding point of welding circular tube 0214 absorbed different, influence welding quality. In order to solve the problem, laser energy absorbed by each welding point of a welding circular tube 0214 is the same, and a rotating motor 0608 rotates to drive a compensation rotating disc 0910 to rotate in the welding process, so that on the basis of determining the positions of a long shaft generating block 0911B and a short shaft generating block 0911C in a generator outer frame 0911A in the previous period, the compensation generator 0911 moves up and down while moving left and right in sliding chutes of a sliding support frame 0912 and a compensation implementing block 0913, and then drives the compensation implementing block 0913 to move up and down; through the lever action of the compensation reverse lever 0918, the support bottom plate 0101 moves up and down opposite to the compensation implementation block 0913, namely, when the welding circular tube 0214 rotates in a welding mode, the support bottom plate 0101 moves up and down to drive the welding circular tube 0214 to move up and down (ellipse adjustment) in the same mode, so that the distance between each welding point of the welding circular tube 0214 and the laser focus position is kept unchanged in the welding rotating process, and circular tube angle welding with good quality is completed.
