METHOD OF SOLDERING CATALYST SUPPORTS IN CATALYTIC CONVERTERS

摘要

Catalytic converter carrier bodies have a jacket and adjacent layers of corrugated or smooth and corrugated metal foils wound or layered in the jacket. The metal foils contact each other and contact the jacket at connecting points, defining flow channels between the metal foils and between the metal foils and the jacket and defining brazing gaps at the connecting points. A method for brazing the carrier bodies includes initially dispersing powdered brazing material with a suitable particle size in a mixture of binder material and liquid. The flow channels are flooded with the liquid mixture for depositing the brazing material in at least some of the brazing gaps. Excess mixture is subsequently removed from the flow channels and the carrier body is then brazed.
