An effect of residual stresses and internal defects on fatigue crack initiation of laser welded sheets

Original language description

The paper summarizes the results of fatigue tests and residual stresses evaluation. The tests at laser welded joints on sheets with 4 mm thickness made from high-strength S700MC steel have been provided. An effect of pores in weld metal on fatigue crack initiation has been investigated and compared with known and many times experimentally approved Murakami's theory that described an effect of internal defects on fatigue properties. The residual stresses redistribution in weld joint has been used as an explanation of significant differences between our experimental results and theory.
