Optimization of Flux for for low wire consumption snd slag produced in Submerged arc welding using fuzzy logic

This study has been conducted to find out the optimal flux for low consumption of wire and slag produced in submerged arc welding.Slag production is essential in SAW but large amount of slag produced and wire consumption is not desirable.So an attempt has been been made in this study to select the proper flux.. Response surface methodology has been used for designing of flux and these fluxes were made by agglomeration technique.The welding parameters such voltage, current and travel speed were made constant so the consumption of wire and slag produced cannot be decided by the welding parameters. It reveals that flux composition may play an important role in this regard. Fuzzy logic optimization suggests that the flux having composition CaF2 5%, FeMn 5% and NiO as 8% is most suitable for low consumption of wire and low amount of slag produced..
