摘要：
A process for producing a body for exhaust gas treatment having a plurality of metallic layers, includes bringing the layers into contact with each other in a connection region. A connection is made by a roller seam welding process in such a way that the layers form passages through which a gas stream can flow. A corresponding body for exhaust gas treatment can especially be used as a filter or catalyst carrier body in the automobile industry.
