Fatigue resistance of laser welded S355 steel sheet
Original language description
The paper contains results of fatigue resistance investigation of laser welded 10 mm thick sheets of a carbon structural S355 steel. High cycle fatigue tests were performed to verify fatigue strength of the sheet containing laser weld performed with optimised laser welding parameters. Though the thickness of the sheet was quite big, resulting endurance limit of the welds and heat affected zone was comparable with that of basic material. In addition, some characteristics of the laser weld like hardness were very self consistent. As expected, fatigue results were characteristic by quite high scatter. Different damage mechanisms were shown. The results are discussed on the basis of fractographical analyses, which provided some quite interesting details about crack initiation mechanisms
