[0028] In this embodiment, the first bracket 100 is first connected to the weapon seat, and then the length of the connecting piece 300 is adjusted so that the second bracket 200 is close to the part to be welded, and the second bracket 200 and the part to be welded are connected to each other, so that the position of the part to be welded can be determined. After the welding of the part to be welded is completed, the first bracket 100 and the second bracket 200 can be removed from the weapon seat and the welded part respectively. By using the above-mentioned welding positioning fixture, the part to be welded is connected to the weapon seat via the second support frame, the connecting piece 300 and the first support frame, so that the part to be welded uses the weapon seat as a positioning reference target. Compared with using the welding surface as the positioning reference target of the part to be welded, the problem of excessive welding error of the part to be welded caused by welding deformation of the welding surface can be avoided.
