Study and Experimental Modelling of Welding Parameters on Hardness of Hot Air Welded Poly Vinyl Chloride (PVC) Plastic

The present work has been carried out to study the effect of some input parameters on the desired responses in the Poly Vinyl Chloride (PVC) plastic welding by hot air technique. The effect of hot air temperature, welding speed and air flow rate has been evaluated on the Hardness of the welded joints. These responses have been analysed using the analysis of variance (ANOVA) and experimental modeling. Plots of significant factors and experimental modeling have been used to determine the best fit relationship between the responses and the model parameters using MINITAB 17. This has been used to determine the most influencing parameter.
