Abstract
In a compound panel welding line, the compound panels discharged from a welding machine are cooled by means of a cooling unit. In the cooling unit, the welded seam is treated with a cooling fluid, in particular a rust-preventative oil. This allows the panels to be cooled and oiled within a very short time and over a very short distance, thus substantially reducing the overall length of a welding line, and greatly facilitating the handling of the compound panels.
