Abstract

Den foreliggende oppfinnelse tilveiebringer den følgende sammenføy- ningsfremgangsmåte som på en enkel og passende måte er i stand til å tilveie- bringe en skjøt som har utmerket styrke og korrosjonsmotstand. Fremgangsmåten for sammenføyning av tofaset rustfritt stål innbefatter: kaldbearbeidelse av tofaset rustfritt stål over i det minste området i nærheten av en buttende overflate av basismetallet for å øke flytegrensen til den kaldbearbei- dede sonen til (1,3 x (minimal nødvendig flytegrense for skjøt) -10)kp/mm2 eller . høyere; innføring av et innførings- eller tilsatsmateriale i et sammenføyningsparti hvilket materiale har et smeltepunkt som ikke er høyere enn 1150° C og en tykkel- se på 10-80 nm; påføring av et trykk på 0,5-2 kp/mm2 samtidig som det besørges avskjerming ved hjelp av en blandet nitrogen/argongass som inneholder argon i en mengde på 0-80 volumprosent; oppvarming av området i nærheten av skjøtepartiet til en temperatur som ikke er lavere enn smeltepunktet til innførings- materialet og lavere enn smeltepunktet til basismetallet og opprettholde tempera- turen i 120 sekunder eller lenger; begrensning av oppvarmingslengden til sam- menføyningspartiet som oppvarmes til en temperatur som ikke er lavere enn 800° C ikke lenger enn 20 mm og oppvarmingslengden til sammenføyningspartiet som ble oppvarmet til en temperatur ikke lavere enn 600° C ikke lenger enn 40 mm; innstilling av avkjølingshastigheten innenfor sammenføyningstemperatu- ren og 400° C ved 50-150° C pr. sek.; for derved å danne et sammenføyningsparti som har en prosentdel ferrittisk fase på 30-70 volumprosent.
