Abstract [en]

In this thesis work a literature survey is done to collect published data for T-welded joints with a thickness of 5-12 mm, produced in high strength steel and treated with HFMI. In addition to this, large structures are researched. The data was evaluated in nominal stress and effective notch stress and compared with the recommended FAT value from the International Institute of Welding (IIW) for post-weld improved joints. It was concluded that not sufficient data exist for T-joints in high strength steel, especially steels of grades with yield strength greater than 450 MPa, and thicknesses of 5-12mm, neither does enough data exist for large structures. The recommended fatigue strength values from the IIW were compared.

Abstract [sv]

I detta arbete så kommer en litteraturstudie att genomföras för att samla data om svetsade t- balkar med en tjocklek på 5-12 mm, av materialet höghållfasta stål och behandlade med HFMI. Stora strukturer kommer även att undersökas. Den samlade datan är utvärderad i nominell spänning och effective notch stress och jämförd med International Institute (IIW) of Welding för efterbehandlade svetsar. En slutsats är att det inte finns tillräckligt med data för svetsade t-balkar i höghållfasta stål med en tjocklek mellan 5-12 mm. Data om stora strukturer bör också utvecklas. De rekommenderade utmattningshållfasthets värden från IIW jämfördes.
