At the same time, the transverse member 9 drives the inner welding assembly 12 through the welding gun displacement assembly 11. Then the transverse member 9 drives the inner welding assembly 12 to weld the inner wall of the flange and the cylinder body. At the same time, the inner welding assembly 12 drives the outer welding assembly 13 to weld the outer wall and flange of the cylinder body. The staff can place the flange on the flange positioning block and position it. The first clamping cylinder clamps the flange (the flange is manually pressed against the side wall of the flange positioning block before clamping). The cylinder body is placed on the first support block and the flange positioning block and positioned. The second clamping cylinder clamps the cylinder body. The servo electric cylinder drives the transverse moving part to move right.
