Abstract

A catalytic muffler is formed by winding together a pair of relatively thin catalytically active foils one of which is corrugated. The wound-together foils are secured together by nondeposit welding to form a rigid insert having longitudinally throughgoing gas passages. This insert is then fitted into a cylindrical housing and welded to the housing once again using a beam-type welder.
