Method for the connection of two workpieces, which dispose over materials having different melting points, comprises producing a material-consistent connection between the workpieces by cold metal transfer welding

The method for the connection of two workpieces (1, 2), which dispose over materials having different melting points, comprises producing a material-consistent connection (7, 6) between the workpieces by cold metal transfer welding, and generating a contour in the contact area of two workpieces so that a positive-fit connection is produced between the workpieces. One of the workpieces is bent in the contact area, and a recesses (8) such as hole, groove or a stamp is introduced in one of the workpieces in the area of the contact region. The method for the connection of two workpieces (1, 2), which dispose over materials having different melting points, comprises producing a material-consistent connection (7, 6) between the workpieces by cold metal transfer welding, and generating a contour in the contact area of two workpieces so that a positive-fit connection is produced between the workpieces. One of the workpieces is bent in the contact area, and a recesses (8) such as hole, groove or a stamp is introduced in one of the workpieces in the area of the contact region. The workpieces are deformed together in the contact area. A hollow edge is introduced in one of the workpieces in the area of the contact area. The contour is introduced in the workpiece, which comprises a material with higher melting point temperature. A light metal is used for one of the workpieces and steel is used as material for another workpiece. An independent claim is included for a connection between workpieces made of steel and light metal workpieces.
