The utility model relates to the technical field of pipe joint machining, in particular to a pipe joint positioning welding core-pulling die. The device comprises a base, a base plate, a connector positioning core, a connector positioning piece, a supporting column, a mounting plate and an air cylinder; by designing the joint positioning core structure capable of moving up and down, after the joint end of the pipe fitting and the joint positioning core are positioned and connected and are welded, the joint positioning core can be driven by the air cylinder to move downwards to be separated from the positioning connection with the pipe fitting, so that the welded pipe fitting can be conveniently and directly taken down manually, and the welding efficiency is improved. Compared with a fixedjoint positioning core structure adopted in the prior art, the pipe fitting needs to be dismounted vertically and upwards manually, pipe fitting damage caused by collision and friction between the pipe fitting and the joint p
