  • Method for manufacturing a crash frame of a battery compartment for battery electric vehicles
    Patent number: 11967727
    Abstract: The invention relates to a manufacturing method for a crash frame of a battery compartment for electric drive vehicles by using metallic sheets which are arranged on top of one another and fixed together and which form in a following step a space by using an inner active media forming process to create walls of a crash frame whereby the space works as a deformation space to protect the battery modules inside the battery compartment against an impact. The invention further relates to the use of the crash frame for a battery compartment.

  • Resistance welding of unweldable metals with thermal sprayed interlayers
    Patent number: 11548087
    Abstract: A method for joining of at least two materials, non-weldable directly to each other with thermal joining processes in a lap joint configuration includes a two step sequence including a first step to apply a thermomechanical or mechanical surface protection layer on the surface of a (stainless) steel substrate and a second step where, a thermal joining process is used to weld the sprayed layer with an applied aluminum sheet without having brittle intermetallic phases in the whole material configuration.

  • Multistage joining process with thermal sprayed layers
    Patent number: 11524351
    Abstract: Method for joining of at least two unweldable materials, non-weldable directly to each other with thermal joining processes in a lap joint configuration, where a two step sequence is used consisting of a first step to apply a thermomechanical or mechanical surface protection layer on the surface of an unweldable material and a second step, where a thermal joining process is used to joint the sprayed layer with an applied layer sheet.

  • Method for Manufacturing a Weldable Metal-Polymer Multilayer Composite
    Publication number: 20190358731
    Abstract: A method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned between at least two metallic layers. At least one of the metal layers is shaped into a three dimensional layer and the metal layers are material closured to each other by a tack weld on the metallic contacts between the metallic layers to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions.

  • Resistance Spot Welding Electrode and Use of the Electrode
    Publication number: 20190160586
    Abstract: A resistance spot welding electrode for forming dissimilar welded lap joints in crash-relevant structural components of the automotive industry made of high-strength materials. The resistance spot welding electrode includes a cap having, at an end portion of the electrode in contact with materials to be welded together during welding, a non-axially symmetrical contact area in order to form, between the materials being welded, a weld nugget with an essentially similar non-axially symmetrical shape.
