Abstract: A method for determining a quality criterion of a welded connection between two conductor ends. The method includes acquiring intensity information of a plurality of image points and depth information of the plurality of image points of an acquisition area covering the two conductor ends, and determining a quality criterion as a function of the intensity information acquired and the depth information acquired.

Abstract: An electronic device, in particular a pulse inverter for a motor vehicle, including a housing with a housing interior. The housing has at least one partition wall, which divides the housing interior in a sealed manner into a first interior region and a second interior region a media-tight interface being provided in a recess in the partition wall, which interface is formed in one piece with the partition wall from a plastic material.

Abstract: A method is provided for producing a winding (1) for an electric machine (10). The winding (1) has conductor elements (2) and two conductor ends (3) of different conductor elements (2) are bonded electrically with one another at a bonding point (4). The method includes arranging at least one material reservoir (5) on the conductor ends (3) to be bonded prior to generating the bonding point (4). The method then includes generating the bonding point (4) by joining the conductor ends (3). The method continues by melting the material reservoir (5) and distributing the molten material reservoir (5) at least over the bonding point (4). Thus, an insulating structure (15) is provided after cooling the distributed material of the material reservoir (5). The insulating structure (15) insulates the conductor ends (3) against their surroundings at least at the bonding point (4).

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.
