A method for shaping a part using a magnetic pulse is provided. A thin conductive layer is positioned on the part. The part is positioned between a coil and a matrix, the conductive layer being arranged between the coil and the part. An induced current, generated by the coil, is configured: to vaporize the conductive layer generating a pressure wave in the direction of the part. Additionally, the induced current is configured to accelerate the part in the direction of the matrix in association with a magnetic field generated by the coil, pressing the part against the matrix, thereby shaping the part. Further, a method for welding a part using a magnetic pulse is provided.

A vehicle drivetrain assembly, and method for making the assembly, including first and second torque transmitting members, one of which is made of aluminum and the other of which is made of steel, and being joined by an electromagnetic pulse weld progressively applied along a radial direction relative to a central axis of the assembly.

A method for producing a multi-layer sliding bearing 1, includes the method steps: —providing a carrier body; —providing a bearing body; —applying the bearing body to the carrier body, wherein a carrier body connecting surface is turned towards a bearing body connecting surface; —deforming a bearing body by applying a magnetic force to the bearing body of using a magnetic force generator, wherein the bearing body is pressed on, by the magnetic force generator, to the carrier body and forms a force-fit and/or positive locking and/or materially bonded connection therewith.
