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.

A method of splicing a trailing end of a downstream metal strip to the leading end of an upstream metal strip, the method comprising 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.
In a strip-treatment installation where a leading end of an upstream strip must be joined to a trailing end of a downstream strip, a splicing apparatus comprising:
- means for overlapping the leading end of the upstream strip with the trailing end of the downstream strip;
- and
- at least one friction-welding head for forming a plurality of friction spot welds between the overlapping ends.
