Abstract

Det beskrives en fremgangsmåte og en anordning for fremstilling av et metallrør, spesielt et flukskjerne- sveiserør inneholdene fyllelementer, omfattende minst ett rekrystalliseringsaduseringstrinn utført med høyfrekvens- induksjonsoppvarming, fortrinnsvis ved en frekvens på minst 10 kHz. Det beskrives også anvendelse av flukskjerne-virer oppnådd med fremgangsmåten for implementering i en bue- sveise-prosess, såsom TIG, MIG, MAG, neddykket-bue eller vertikal elektroslagg sveiseprosess.
