Filter or semi-permeable membrane element construction prevents edge leakage by heat-laser induced fusion sealing under inert gas blanketing

The peripheral edge of a metallic filter or membrane panel is fused by heat-laser, under inert gas blanketing, to prevent in-use ingress of suspension through the edge. Verfahren zur Bearbeitung poröser, metallischer Membranen oder Filtermedien, wobei man Teile der Membran bzw. des Filtermediums mit...

Summary:The peripheral edge of a metallic filter or membrane panel is fused by heat-laser, under inert gas blanketing, to prevent in-use ingress of suspension through the edge. Verfahren zur Bearbeitung poröser, metallischer Membranen oder Filtermedien, wobei man Teile der Membran bzw. des Filtermediums mittels eines Laserschweißgerätes thermisch behandelt.
