RESISTANCE SPOT WELDING ELECTRODE AND USE OF THE ELECTRODE

METHOD FOR MANUFACTURING A CRASH FRAME OF A BATTERY COMPARTMENT FOR BATTERY ELECTRIC VEHICLES

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

The invention relates to a method for joining of at least two 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 a (stainless) steel substrate (1) and a second step where, a thermal joining process is used to weld the sprayed layer (2) with an applied aluminum sheet (3) without having brittle intermetallic phases in the whole material configuration.

METHOD FOR MANUFACTURING A WELDABLE METAL-POLYMER MULTILAYER COMPOSITE

The invention relates to a method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned (4) between at least two metallic layers (1, 2, 5). At least one of the metal layers is shaped into a three dimensional layer (2), and the metal layers (1, 2, 5) are material closured to each other by a tack weld (3, 8) on the metallic contacts between the metallic layers (1, 2, 5) to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions.

MULTISTAGE JOINING PROCESS WITH THERMAL SPRAYED LAYERS

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.
