Abstract: A method is provided for producing a stator arrangement that has a stator core and a winding arrangement. The stator core has stator slots. The winding arrangement has winding elements with a conductor and an insulation layer. Each winding element has two interconnected winding element legs with two winding element end portions on each winding element leg. The method includes positioning the winding elements on the stator core so that the winding element legs extend through one of the stator slots with winding element end portions protruding on a first side of the stator core. The method then includes using a first laser arrangement to remove the insulation layer from regions of the winding element end portions. The method then includes pressing the first and second winding element end portions against one another and using a second laser arrangement to carry out welding.
