Abstract

Multi-objective optimisation of the mechanical properties of single- and twin-wire welded joints is presented. Diversity in functional relation between various mechanical properties and welding process parameters is mapped using artificial neural network modelling. An aggregate index as a function of process parameters is proposed for collective assessment of the mechanical properties namely, ultimate tensile strength, yield strength, % elongation, % reduction in area, impact toughness, fatigue life, and heat affected zone hardness. Optimisation of the aggregate index through simulated annealing indicates existent of multiple near optimum solutions facilitating development of a process window. The quality plots visualising the effects of process parameters on combined mechanical properties suggest superiority of twin-wire over single-wire welding.
