Title

EFFECT OF WELDING PARAMETERS ON BEAD GEOMETRY IN A-TIG WELDING PROCESS ON AZ-91 Mg ALLOY

Abstract

In present work, an effort has been made to investigate the effect of welding parameters on bead geometry performance of AZ-91 magnesium alloy using A-TIG welding process. Mathematical models have been developed by using 2- level half factorial technique to predict the bead geometry within the range of control parameters or operating variables for activated tungsten inert gas welding process. The models developed can be employed easily in automatic or robotic welding, in the form of program, for obtaining the desired high quality welds. Welding current, active flux, welding speed and gas flow rate are taken as welding variables by keeping all the other variables constant to evaluate the bead geometry. It has been found that penetration increases significantly with CdCl2 as compared to TiO2 flux and welding current also have positive effect on penetration but penetration decreases with increase in welding speed and have negligible effect by shielding gas flow rate. The models have been developed from the observed values, with the help of design matrix. The adequacies of models have been tested by use of analysis of variance technique and significance of coefficients was tested by students ‘t’-test’. The combined and main effect of different parameters involved has been presented in graphical form.
