Monolithic metal catalyst for exhaust gas purification - with electron beam welds between foils and to housing

Monolithic metal catalyst for the purification of exhaust gases from i.c. engines, e.g. from motor cars, consists of two metal foils which produce gas passages and are wound to a roll for insertion in a housing. The foils are jointed to each other, and the roll is joined to the housing, by electron...

Summary:Monolithic metal catalyst for the purification of exhaust gases from i.c. engines, e.g. from motor cars, consists of two metal foils which produce gas passages and are wound to a roll for insertion in a housing. The foils are jointed to each other, and the roll is joined to the housing, by electron beam welding. This provides a reliable fixture of the thin (5/100 mm) metal foils to each other. The roll is fixed in the housing firmly enough to resist all shocks and vibrations.
