The invention relates to a method for joining a composite sheet to a metallic substrate, wherein the composite sheet has at least one metallic top layer and at least one non-metallic layer which consists of a plastic material, wherein an opening is introduced into the composite sheet, and wherein at least one joining element is provided which is inserted into the opening of the composite sheet. A method for joining a composite sheet to a metallic substrate with process reliability and of specifying a corresponding structure is achieved by forming the joining element as a metallic sleeve, wherein the metallic sleeve is deformed, so that it joins together with the composite sheet in a form-fit and force-fit manner, and wherein the metallic sleeve is firmly bonded to the substrate with the end pointing towards the substrate using a filler material, wherein the filler material is arranged inside the sleeve.

Method for joining a composite sheet to a metallic substrate

A method for producing a metallic component (B) allows adjoining zones (Z, Z, Z) having differing material properties to be produced in a manner which is simple in terms of production. This is achieved in that a sheet metal element (E) heated to a forming temperature is shaped in a forming tool () into an end-shaped component (B), wherein the forming tool () has a temperature adjustment means for adjusting the temperature of at least one of the portions () thereof that comes into contact with the sheet metal element (E) during the forming process, and in that the forming speed is controlled in consideration of the time for which the portion () of the forming tool () that is regulated with regard to the temperature thereof is in contact with the respective region (E, E, E) of the sheet metal element (E) that rests against said portion.
