  • Connecting seam between two thin-walled sheet-metal parts
    Patent number: 10357849
    Abstract: A connecting seam is formed between two thin-walled sheet-metal parts as a laser weld seam or laser soldered seam as additional material is supplied, respectively. The sheet-metal parts have flange portions for formation of a connecting region. At least one flange portion includes in the region of a joining zone a bead which is at least partially surrounded or filled by solidified melt from seam material after the production of the connecting seam.
    Type: Grant

    Assignee: AUDI AG
    Inventors: Frank Stohler, Gerhard Gaull, Jochen Rintelmann
  • Component arrangement and method for producing the component arrangement
    Patent number: 9849758
    Abstract: A component arrangement includes a first sheet metal profile part and a second sheet metal profile, each first and second profile parts having respective flanges and being arranged relative to each other so that the respective flanges overlap, wherein the first and second profile parts are connected to each at the respective flanges via a laser welding connection, which extends over a welding seam length, wherein the laser welding connection is formed by at least two welding seams which extend parallel and at a distance to each other.

  • Method for preparing a workpiece for subsequent laser welding and method for joining workpieces through laser welding with lap joint
    Patent number: 9849542
    Abstract: In a method for preparing a workpiece for subsequent laser welding, a recessed structure in the form of at least two grooved line elements is formed by a laser beam in a surface of the workplace, with the line elements having a common starting point from which the laser beam moves onwards to produce the line elements. Solidifying material melt of the workpiece is hereby accumulated in an area of the starting point to produce a nub-like elevation sized to extend out beyond the surface of the workpiece.
