Abstract (en)
[origin: FR2769082A1] The invention concerns a plate of an array of heat transfer plates (1), comprising a central part provided with undulations (11) and edges with smooth surface, characterised in that it is formed by at least two metal plate portions (12; 13) of different metallurgical compositions, abutted to form at least a joint face (14) and mutually connected by a continuous and sealed weld seam (15) extending over the whole length of said joint face (14). The invention also concerns methods for making this type of plates and an array of heat transfer plates comprising such a plate.
