Comparison of experimental and theoretical residual stresses in welds: The issue of gauge volume

Weld-induced residual stresses in a prototype dragline cluster and comparison with design codes

“…The experimental validation of FE modelling technique used in Sysweld+ had been performed in single-bead-on-plate specimens and neutron diffraction measurements as indicated in [8] and [20].…”

Finite element analysis of residual stress distribution in a thick plate joined using two-pole tandem electro-gas welding

“…Several different types of residual stress measurement techniques can be used, such as the hole-drilling method, X-ray diffraction (XRD), neutron diffraction, ultrasonic methods, the Barkhausen noise method, and magnetic methods. XRD and the neutron diffraction method are non-destructive methods using radiation based on the volume difference between the normal and distorted alignment of lattices of the material (Price et al, 2008). XRD, which is one of the most accurate methods, was used in the present study to measure the residual stresses on the surface of the welded specimen.…”

Modeling of Temperature Field during Multi-Pass GMAW Surfacing or Rebuilding of Steel Elements Taking into Account the Heat of the Deposit Metal

“…Mahapatra et al [18] carried out an analysis of the impact on the temperature distribution of parameters as the electrodes diameter, welding speed, current voltage and intensity during arc welding in gas shields. Price et al [19,20] used double heat source and package Sysweld+ to FE thermal analysis in a single-weld bead-on-plate (MIG). Kumar and Debroy [21] proposed a model of heat and liquid transfer to determine the influence of the fillet joints' tilt angle and the welding position on the temperature profile, the velocity field and the shape of the weld pool.…”
