Abstract
Det er beskrevet en fremgangsmåte for å oppnå forhøyet styrke, spesielt utmattingsstyrke, i sveisede aluminiumsforbindelser og -komponenter som er kjenntegnet ved at den myke sonen som oppstår ved sveisingen underkastes kaldbearbeidelse ved sveisetåen hvorved området påvirkes av en kompresjonskraft som er tilstrekkelig til å frembringe en synlig og/eller målbar fordypning ved sveisetåen. Det er videre beskrevet et sveiset aluminiummateriale som ved den nevnte fremgangsmåten er gitt forbedret styrke, spesielt utmattingsstyrke.A method of obtaining elevated strength, especially fatigue strength, is described in welded aluminum joints and components which are characterized in that the soft zone arising from the welding is subjected to cold work at the weld toe, the area being affected by a compressive force sufficient to produce a visible force. and / or measurable recess at the weld toe. Further, a welded aluminum material is disclosed which, by the aforementioned method, provides improved strength, especially fatigue strength.
