Importance of different filler material on residual stress mitigation in dissimilar joining of nuclear grade T/P92 and AISI304 steel
Pavan Meena, Ramkishor Anant
Abstract. Joining of dissimilar ASMW SA335 P92 and AISI304 steel produces residual stresses due to solidification and cooling incompatibilities. Thermal conductivity and specific heat variations with temperature, affect heat transfer rates. Differential cooling behaviors, thermal expansion, and Poisson’s ratios are the main reason behind inducement of residual stresses after joining. This study employs finite element method to thoroughly investigate the causes and mechanisms underlying the generation and distribution of residual stresses while using the different filler materials. The findings indicate that the primary sources of welding-induced longitudinal residual stress (σL) are the thermal shrinkage and phase transformation process. Additionally, apart from these two processes, the quenching process contributes to the production of transverse residual stress (σT). It was observed that the maximum (σL) typically reaches the yield strength (σy) of the base metal (BM) at ambient temperature.
