ABSTRACT:
The invention relates to a method for the manufacture of a metallic matrix which is "monolithic", is coated with a catalysis promoting metal oxide and is disposed in a metal casing, in which the matrix is composed of alternately disposed plain and corrugated or folded metal sheets or plates, in which these sheets are stacked in a pile or are wound into a spiral. The method comprises a special resistance welding on the end faces of the matrix and arc welding of the side face of the matrix to the side of the casing, on which the metal oxide is applied.
