The transfer robot transfers the steel pipe to the head-tail type welding positioner and clamps the steel pipe by the active and passive positioning mechanism of the head-tail type welding positioner, then transfers the welding plate to the welding position of the steel pipe, and the welding robot completes the welding work. During welding, the passive end of the pipe is clamped by a passive air chuck. When the jacking cylinder works, the jacking shaft is driven to move forwards and backwards, and the jacking shaft drives the passive pneumatic chuck to move forwards and backwards, so that the clamping work of the workpiece is completed. The driving end of the pipe fitting is clamped by the driving air chuck, and the servo motor drives the hanging piece on the driving air chuck to rotate.

Even if the conductive head is worn after long-term use, the compression spring can automatically adjust and always keep the compression of the conductive head. Because the anti-rotation flat wire structure is arranged on the conducting rod, the conducting rod cannot be driven to rotate when the turntable rotates. And outputting the welded finished product by a welded finished product output roller way.
