Abstract

Fremgangsmåte for tilvirkning av sveisede strukturer med utmerkede egenskaper til å hindre vekst av sprøbrudd som oppstår i sveiseskjøter, kjennetegnet ved at den omfatter det trinn å danne en reparasjonssveis, som har en større seighet enn den til en buttsveis og en ytterkant med en vinkel f i forhold til buttsveisens lengderetning som ikke er mindre enn 1 0 grader og ikke mer enn 60 grader, ved reparasjonssveising i et område for å stanse et sprøbrudd i en buttsveiseskjøt der et sprøbrudd har stor sannsynlighet for å propagere etter fjerning av en del av buttsveiseskjøten i nevnte område ved uthuling eller maskinbearbeiding.
