Estimating the term…
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.
In a resistance roller welding machine for seam welding two can components movable in a predetermined direction, including oxidation suppression means operable for at least partially suppressing oxidation of the hot welding seam,
