摘要：
Aiming at the problem that it is difficult to manufacture truss structures, this paper proposes a point-by-point additive manufacturing technology for space truss structures based on cold metal transition (CMT) spot welding. First, the optimal process parameters are obtained through process forming tests, and then the force analysis during the welding process of the truss structure is performed. Based on the force analysis in this paper, a mathematical model of the force analysis in the truss welding manufacturing process is proposed on this basis, which effectively solves the collapse of the column, the drip of molten droplets on the column, and the collision of the torch contour with the component during the truss forming process. Finally, a truss forming test was performed to change the bending angle of a single column to verify the correctness of the mathematical model and the feasibility of the truss welding method.
