摘要:
A method of producing a corrugated metal sheeting including a flat metal sheet and a corrugated metal sheet joined to each other, which sheeting is used to produce a carrier or honeycomb structure for carrying catalytic agents used for purifying exhaust gases from, for example, an internal combustion engine of an automobile. In the method, the flat and corrugated metal sheets are brought together so that corrugations of the corrugated metal sheet are successively brought into contact with the flat metal sheet in such a manner that the corrugated metal sheet is freely movable to thereby release resilient stresses therefrom, and a laser beam is incident on a contact line between the flat metal sheet and each of the corrugations of the corrugated metal sheet, to thereby weld them to each other.
