Abstract

The invention relates to a procedure for making a pressure-sealed connection of thin-walled articles made of metal, in particular plate-shaped metal sheets, such as heat-exchanger plates, which are provided with an enamel layer (3, 8) at least on one side as corrosion protection. In order to obtain a pressure-sealed and self-retaining connection of the articles to be connected, which requires no joining fillers or joining agents or no subsequent treatment of the joint, it is proposed that the articles to be connected to one another be correctly positioned and that they be pressed against one another at least at the joining surfaces (4) and heated in such a way that the enamel layer (3, 8) located between the joining surfaces (4) is changed into a pasty state and produces a self-retaining connection of the articles. <IMAGE>
