  • Method for welding a weld-on element onto a counterpart
    Patent number: 10016849
    Abstract: A method for welding a weld-on element onto a component is proposed, comprising at least the step that, before the welding process, at least one of the parts being connected is wetted with a wetting agent over the full area and uniformly in layer thickness in a welding region.
    Type: Grant
    Filed: January 22, 2014
    Date of Patent: July 10, 2018

  • Welding method and apparatus
    Patent number: 9993892
    Abstract: A method and an apparatus for joining first and second sheet metal parts includes a support where the first and second parts are positioned with an edge of the second part surrounded by a beading flange of the first part. A joining electrode is positioned adjacent to the beading flange and a counter-electrode is positioned adjacent to the second part. An abutment of a tong-type welding apparatus in placed in contact with the support, and the joining electrode and the abutment are urged toward one another to press or clamp the beading flange between the joining electrode and the support. An electric current is applied to the beading flange using the joining electrode and the counter-electrode to weld the parts together.
