Effect of input parameters on weld bead geometry and weld dilution for weld surfacing of flux cored 308L stainless steel on low carbon steel
Materials Today: Proceedings(2022)
Abstract
Weld surfacing helps to reap the benefits of superior quality of surfacing material with the low cost of base material. Weld surfacing is popular for manufacturing corrosion resistance, wear resistance and high temperature materials. Submerged Metal Arc Welding and Metal Inert Gas Welding are the most common methods used in weld surfacing. MIG welding is easy to use, fast, good weld quality and good penetration so it is most popular. Stainless steel and Nickel are the most popular surfacing materials. Results have shown considerable improvements in properties like wear resistance and corrosion resistance after weld surfacing. This project work aims to develop the mathematical model for the effect of Welding speed, feed rate and Voltage on the bead geometry and weld dilution. Statistical method using Central Composite rotatable factorial design was used to carry out the experiment with all the three factors at five levels. The analysis of result was done by Response Surface Methodology (RSM). ANOVA analysis was performed to check the adequacy of the models and parameters were optimized for weld surfacing.
