A positive effect of compressive residual stresses on fatigue strength and damage mechanisms of laser welded structural carbon steel sheets

Original language description

The contribution deals with fatigue resistance of laser welded 10 mm thick sheets of a carbon structural S 355 steel. High cycle fatigue tests were performed after optimizing laser welding parameters. Failure occurred mostly in baseic material, so endurance limit of the welds and heat affected zone was higher than that of basic material. The results are discussed on the basis of fractographical analyses, which provided some quite interesting details about crack initiation and growth mechanisms.
