Measurement and Numerical Analyses of Residual Stress Distribution Near Weld Joint

Abstract The aim of this paper is experimental X-ray verification of residual stresses in high strength steel materials after welding and numerical approximation of all stress components on the surface of the specimen. Welding of plates with square notch without thermal preprocessing or postprocessing can cause normal and tangential stresses in basic material. These stress functions will be evaluated near weld joint. The following numerical analyses can show the type and the size of loadings that can be transferred with this type of joined constructions.
