SOLDERED METALLIC HONEYCOMB MEMBER HAVING SPACING ELEMENTS IN ZONES OF SOLDERING AND METHOD FOR MAKING IT Russian patent published in 2002 - IPC

Abstract RU 2179097 C2

FIELD: manufacture of members that may be used as catalytic neutralizers of exhaust gases of transport vehicles. SUBSTANCE: metallic sheets partially have structure providing passages for flowing fluid. One of adjacent sheets has pressed protrusion turned towards other adjacent sheet and serving as spacer. Solder is applied in zone of protrusion into formed soldering gap. Method for making honeycomb members allows to reduce loss of prestress effort of metallic sheets at soldering process. EFFECT: maximally uniformed soldered joints of ready honeycomb sheets. 10 cl, 7 dwg
