Evaluation of MIG welding process parameter using Activated Flux on SS316L by AHP-MOORA method

In this research work an attempt to investigate the influence of different single component oxide flux in Activated Metal Inert gas (MIG) welding of AISI 316L. Two different fluxes SiO2, Cr2O3 were used to bead on plate welding. 6 mm thick plate of stainless steel weld with MIG welding, Carried out under some process parameter. The process parameters such as welding speed, current, Arc voltage and response are welding dimension such as depth of penetration, Bead width were studied. The Welding experiments were conducted with L9 orthogonal array using minitab 16 softwere. A Same Nine set of parameter used for the without flux, With Sio(2) and with Cr2O3 flux. Total 27 experiments had done at work. AHP-MOORA and ASRS method was applied to optimizing the MIG welding process parameters and result indicated the enhanced penetration in weld achieved with use of fluxes Sio(2), Cr2O3. On the basis of present result it is considered that the centripetal Marangoni convection & Constricted arc as a mechanism in increasing the penetration of activated MIG welding. The metallurgical characteristic Hardness of weldment was evaluated using Vickers-Hardness. The purpose of this work to investigate the effect of oxide fluxes on weld morphology & welding parameter. The optimization of Parameter with using AHP-MOORA and ASRS method. (c) 2017 Elsevier Ltd. All rights reserved.
