When the raw materials are pushed to the surface of the connecting mounting frame, stop the operation of the second pusher, and then start the first pusher to push the raw materials on the surface of the connecting mounting frame to between the two rectangular limit frames.

When the welding head is welding the raw material, the hydraulic movable frame is started to drive the welding head to weld the raw material from top to bottom;

[0027] S6. After the welding of part of the raw material is completed in S5, the motor is started to rotate the raw material in the direction through the fixed ring and the two extrusion blocks. After the position of the raw material is adjusted, welding can continue.
