The invention pertains to a method for manufacturing a sandwich sheet (15) with the steps of: making available an unprocessed sandwich sheet (9) with a first metal sheet (10), a second metal sheet (11) and a plastic layer (12), in which the plastic layer (12) is arranged between the two metal sheets (10, 11), locally heating the metal sheet (10, 11) and locally heating the plastic layer (12) in a local connecting region (14), deforming the metal sheet (10, 11) in the local connecting region (14) such that the heated plastic layer (12) is displaced between the two metal sheets (10, 11) in the local connecting region (14) and the two metal sheets (10, 11) are contacted in the local connecting region (14), and welding together the first and the second metal sheet (10, 11) in the local connecting region (14), in which the two metal sheets (10, 11) were contacted, such that the two metal sheets (10, 11) are connected to one another by means of a welded joint (16) in the local connecting region (14), wherein a tool (17) is placed onto the outer side of the metal sheet (10, 11) in the local connecting region (14) and the tool (17) is moved relative to the metal sheet (10, 11) on the outer side of the metal sheet (10, 11) in the local connecting region (14) such that the metal sheet (10, 11) is heated in the local connecting region (14) due to the friction between the tool (17) and the metal sheet (10, 11) and the plastic layer (12) is heated in the local connecting region (14) by the heated metal sheet (10, 11). |
