Abstract

A catalytic converter housing arrangement includes inlet and outlet funnels having large diameter ends mounted by connection bevels at the ends of a wound metal sheet forming a tubular central part of the catalytic converter and welded to the bevels. The funnels are produced from tubular blanks by expanding one end and drawing in the other end. This results in a significant reduction in weight compared with funnels which are deep-drawn from sheet-metal blanks.
