Abstract
In an apparatus and a method of at least partially suppressing oxidation of can components or the like during resistance roller welding with the aid of an inert gas, the steps include welding the can components to one another, so as to obtain a hot welding seam, supplying the inert gas to the hot welding seam so as to envelop it at least partially, and to create a region of the inert gas in contact with the surrounding atmosphere, so that oxidation of the hot welding seam is at least partially suppressed.
