Abstract

A method of splicing a trailing end of a downstream metal strip to the leading end of an upstream metal strip. The method has the steps of overlapping the leading end of the upstream strip with the trailing end of the downstream strip, and thereafter friction welding the overlapping ends together at a plurality of spots at which respective spot welds are thereby formed.
