The first driving member can then drive the first resistance welding machine assembly to move relative to the support platform so that the welding head and the clamping assembly are away from the truss (during the above welding process, since pressure is applied between the head vertical rib and the upper support beam in the truss, the upper end of the head vertical rib can be more reliably welded and fixed to the upper support beam in the truss);Then the second driving assembly can drive the movable frame to move upward. After the movable frame moves upward, the fourth driving member can drive the two second clamping arms to rotate relative to each other so that the upper ends of the two second clamping arms approach each other and clamp the lower ends of the head vertical ribs and the head transverse ribs located on the end of the truss. At this time, the two electrodes in the second resistance welding machine assembly can form a circuit through one of the second clamping arms, the head vertical ribs, the head transverse ribs and the other second clamping arm, and a welding arc can be generated between the lower ends of the head vertical ribs and the head transverse ribs located on the end of the truss to weld the lower ends of the head vertical ribs and the head transverse ribs together. After the welding is completed, the fourth driving member can drive the upper ends of the two second clamping arms to move away from each other and release the head vertical ribs and the head transverse ribs. Finally, the second driving assembly can drive the movable frame to move downward and reset. After the above process, the upper ends of the head vertical ribs can be welded and fixed to the support beam located above in the truss, and the lower ends of the head vertical ribs can be welded and fixed to the head transverse ribs located on the end of the truss.

It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible.
