X-Ray Diffraction Analysis at Ultrasonic Welding
Résumé
In the article [2] the author present experimental investigations regarding of residual stress distribution in weld bead vicinity of submerged arc welded naval plates. In this way, residual stresses from vicinity of weld bead acts like compressive stress. The ultrasonic welding is acting in order to compress the weld bead and the heat affected zone. In this paper is presented X-ray analysis to obtain information about mosaic block dimensions, micro stresses fields and density of dislocations.
