摘要： The invention relates to a composite material in strip or sheet form which consists of two steel cover sheets (1, 2), which are resistance-welded via electrically conductive bodies (4), and an intermediate layer (3) which consists of a filler material. The bodies (4) are embedded into said filler. The bodies (4) are configured as lentiform disks which lie flat between the cover sheets (1, 2). Such a composite material is produced by applying in a continuous mode the filler material (3') for the intermediate layer in a paste-like condition onto a strip (1') which represents the first cover sheet (1). The lentiform disks (4') are placed on the filler material (3') and are pushed into said material in a welding gap (8) formed by two contact rollers (6, 7) of a resistance welding device by way of a strip (2') which represents the second cover sheet (2) at least until the lentiform disks and the sheets contact. The lentiform disks are substantially flattened during welding with the strips (1', 2').

摘要： The invention relates to a method for welding a double-layer sheet (1, 2), especially a knobbed sheet having an intermediate layer (5), to a jointing sheet (8) by spot or roller welding. Before the jointing sheet (8) is welded to the two cover sheets (1, 2) of the double-layer sheet which are maintained at a distance to each other by the intermediate layer (5), the area (11) around the welding point (12) is burnt so as to be freed from the intermediate layer (5) by a current which is introduced across a wide area into the cover sheets (1, 2) by the welding electrode (9, 10) applied to same and carried via a shunt located near the welding point (12). Thereafter, the sheets are brought into conductive contact by the targeted, local application of pressure and the welding is completed.
