摘要

Supplementing an alternative to laborious and resource-intensive trial-and-error experimental techniques, computational modeling and simulation have demonstrated encouraging potential in assessing the various facets of experimental investigations in engineering. The numerical investigations of the microwave hybrid heating (MHH)-based joining process, which has transpired as a modernistic technique owing to its momentous advantages in contrast to conventional joining techniques, have been performed elaborating the different constituents of analytical studies. The work comprehensively evaluates the multiple dimensions of analytical modelling and simulation of microwave processing for joining metallic materials. Further, in this case study, the first reported integrated analytical and experimental investigation into varying power effects on MHH-based joining of a challenging material, i.e., magnesium alloy, AZ31B with nickel filler using a microwave applicator that produced an electromagnetic field of 2.45 GHz. The computational model was evaluated for imitating the thermal and electromagnetic behavior of the MHH processing of AZ31B. Correspondingly, the model was rigorously validated delivering a variation of less than ±3.82 %, the model's predictions closely replicated the experimental findings. Subsequently, the model facilitated a multi-parametric study of the MHH-based joining process. Furthermore, the influence of input parameters was examined by evaluating the joints fabricated through physical characterization techniques and corroborated in mechanical characterization, bestowing a significant addition to the current body of knowledge.
