... the joints (electrical resistance) [ Messler 1999 ; O’Brien 1991 ]. Filler metals may be used to supplement the fusion process for components of similar composition, as, for example, when the joint gap is wide and, possibly, of variable width. In that situation, the filler is often chosen to have...

This strategy introduces the final tube radius in a wide region next to both band edges already in the first stands. Here, an upper and a lower roll can directly form the geometry easily with a correlating rolling gap...
