“…Now accurate predication can be realized for welding deformation, welding stress and welded joint microstructures by using finite element method (FEM), it also provides reference to prevent cracking or buckling, which is caused by local production internal structure damage. [4][5][6] It is necessary to study the effects of welding parameters on the quality of welding of SA508Gr4 steel in order to achieve the optimum weldability.…”

“…For the simulation of multi-pass welding, the addition of each weld pass was modelled by the ANSYS element birth and death technique [16]. A complete FE model including filler metal was built at the start; however, all elements representing filler metal were deactivated with the element death option in the software.…”

The detailed procedures of experiments and numerical simulations to investigate the modification of as-welded stress after milling a local region from the welded plate are presented. A three-dimensional (3D) finite element model was employed to simulate the residual stress induced by multi-pass welding. Taking the as-welded residual stress as the initial stress state, the stress modification of as-welded stress by local material removal with a mill process was also numerically investigated. A welding experiment, milling process, and stress measurements were carried out to validate the numerical analysis. The local material removal with a milling process was considered as a simple stress relief process during the finite element simulation, which was validated by the experimental results. With the proposed numerical model, the modification of as-welded through-thickness stress owing to local material removal was discussed. Investigated results showed that less local material removal does not seem significantly to influence the stress distribution and magnitude at the weld centreline; by increasing the thickness of the material removal, the through-thickness transverse stress within the weld zone changed more noticeably than the through-thickness longitudinal stress, while within the region far from the weld seam, the through-thickness longitudinal stress largely increased, as opposed to the through-thickness transverse stress, which changed little.

“…Dean Deng has reported that the welding simulation model for laser and GTAW processes with Gaussian and double ellipsoidal heat source model with constant and moving heat sources for understanding the temperatures, distortion and residual stresses in weldment of various joints for plate and pipe structures [2][3]. The 3-Dimensional model was developed for multipass dissimilar materials to understand the temperature distributions, distortion and residual stresses in the weldment using the ABAQUS packages [4]. Suresh and Harinadh have reported on various heat fluxes for joining similar and dissimilar butt joints for gas tungsten arc welding and laser beam welding process to understand the temperature distributions, distortion and residual stress developed in the process simulations for nuclear application materials [5][6][7].…”

In the present analysis, thermo-mechanical process was employed to study the thermal and structural behaviour of three pass dissimilar butt-joints of SS316L to Inconel625 alloys. The temperatures evolution and residual stresses developed in the weldments were reported for each pass in the transverse direction to fusion zone. The Ansys Parametric Design Language (APDL) used for modelling and analysis of welding process with the double ellipsoidal heat source. The temperature dependent thermal and mechanical properties used in the simulation process. The residual stress is compressive in SS316L side compared to Inconel 625. The residual stress is within the yield limits of both base materials. The results obtained from the simulation process will be helpful for maintaining the structural integrity.
