Abstract
The invention relates to a light structural steel plate in the form of a hump plate and to a process for its production. The light structural steel plate comprises a mould-pressed steel hump plate (1) and a flat aluminium plate (3) connected thereto substance-to-substance at a the hump end faces. The substance-to-substance connection is produced by the feature that after the surfaces to be interconnected at the hump end faces have been activated by means of a laser beam (5), said surfaces are metallically connected under pressure. The decisive factor is that the material of the plates (1, 2) does not pass into the molten phase during activation by means of the laser beam (5).
