Semi welded plates are built up in plate cassettes. A plate cassette is 2 plates welded together by means of laser welding. The advantage by this construction is on the one side welded plate channel and on the other side a traditional plate channel with gaskets making assembling and cleaning of this side easier. On the welded side there are two specially produced corner hole gaskets creating the tightening between the two cassettes. Thus the gasket is reduced to a minimum on the welded side.
