The correlation of weld microstructure and properties with element transfer in SAW welds

Abstract

This study explores the effect of various elements transfer to the welds on its microstructure and properties. The fluxes were designed using RSM and were made by agglomeration technique. This study reveals that the pearlite or ferrite formation in the welds depends upon the flux constituents. The carbon, manganese, oxygen and nickel transfer have been correlated with the pearlite formation in the welds. The welds dilution also shows a significant effect on weld properties.
