Description
  • Thick sheets from cold forming steel were joined by double-seded laser welding with filler wire and the originated residual stresses were analysed on the cross-section by XRD. The obtained 2D maps shows that high compressive stresses exceeding 55500 MPa occur in the direction peroendicular to the weld and compressive stresses arround 200 Mpa in the HAZ. This should benefically influence the behaviour of the weld under dynamic loads and corresponds to the experience that cracks are more likely to originate in the base materiál rather than in weld or HAZ.
