<p>Joining part (2) for a welded joint between heat transfer plates (1) in a plate heat exchanger, said joining part serving to join stacked heat transfer plates (1) to each other and said joining part (2) being mounted between the edge portions of the stacked heat transfer plates (1), whereby said joining part (2) is solidly melted with the metal of the heat transfer plates (1) during the seam welding process. The invention is implemented by making the joining part (2) from a raw material of a different composition than that used for making said heat transfer plates (1). <IMAGE></p> |
