A gear shift lever welding jig comprises a V-shaped rod positioning assembly and an L-shaped rod positioning assembly. The V-shaped rod positioning assembly is provided with a first positioning grooveand an axial positioning block. The tail end of a V-shaped rod is arranged in the first positioning groove in a matched mode, and the head end of the V-shaped rod is pressed on the axial positioningblock in an abutting mode. The L-shaped rod positioning assembly is provided with a positioning through hole and a vertical limiting structure. The head end of an L-shaped rod is inserted into the positioning through hole, and the tail end of the L-shaped rod is pressed on the vertical limiting structure in an abutting mode. According to the gear shift lever welding jig, the V-shaped rod and the L-shaped rod can be stably and accurately positioned, the welded lengths of the V-shaped rod and the L-shaped rod are ensured, and the strength of a gear shift lever is improved accordingly.
