The utility model provides a stator core welding tool. The stator core welding tool comprises an upper module, a lower module, a guide assembly for connecting the upper module and the lower module, an expansion mandrel for positioning the inner diameter, a center shaft for driving the expansion mandrel to expand or contract, a center fixing column for fixing and guiding the center shaft to slide up and down, and a pressing assembly fixedly connected with the center shaft. When the upper surface of the center shaft slides downwards along the center fixing column after being pressed by the downward pressing assembly, the conical surface of the center shaft pushes the expansion core shaft petals to horizontally move outwards in the radial direction of the expansion core shaft petals to be opened, and therefore the inner diameter of a product is expanded. According to the utility model, iron core laminations can be tidied and positioned, the positioning precision of the iron core laminations is improved, the prec
