TL;DR: In this article, an attempt has been made to solve the correlated multiple criteria optimization problem of submerged arc welding, where the target was to search an optimal process environment, capable of producing desired bead geometry parameters.

TL;DR: In this article, the effect of current, gas flow rate and nozzle to plate distance on quality of weld in metal inter gas arc welding of AISI 316L austenitic stainless steel has been studied through experiments and analyses.

TL;DR: In this article, the grey-based Taguchi approach has been extended to tackle correlated multi-objective optimization problems, in which different priority weights are assigned to different responses, according to their relative importance.

TL;DR: In this article, the effects of welding parameters: welding current, gas flow rate and nozzle to plate distance, on ultimate tensile strength (UTS) and yield strength (YS) in MIG welding of AISI409 ferritic stainless steel to 316L Austenitic Stainless Steel materials.

TL;DR: In this paper, powder-mixed electro-discharge machining on Inconel 718 was carried out by mixing SiC powder in the dielectric media in consideration with varied peak discharge current, and the morphology and topographical features of the machined surface including surface roughness, crack density, white layer thickness, metallurgical aspects (phase transformation, crystallite size, micro-strain and dislocation density), material migration, residual stress as well as micro-indentation hardness, etc., are studied.
