摘要
The invention concerns a composite material in band or slab form made of two cover plates (1, 2), made of steel, which can be resistance welded together via electrically conductive bodies (4), and an intermediate layer (3) made of a filler material in which the bodies (4) are embedded, with the bodies (4), which are implemented as curved slugs, lying pressed flat between the cover plates (1, 2). This type of composite material is produced in that the filler material (3') for the intermediate layer (3) is applied as a paste to a band (1') serving as the first cover plate (1) as it passes by and the curved slugs (4') are, after being laid on the filler material (3'), pressed into it at least until contact is made via a band (2') supplied as the second cover plate (2) in a welding gap (8) formed by two roller electrodes (6,7) of a resistance welding device and the slugs are largely pressed flat with the bands (1', 2') during welding.
