Abstract:
The current investigation is intended to discover the effect of pulsed current TIG welding
process parameters on tensile properties of Alloy AA6061 T6 material. Peak current, base current and
frequency were cautiously decided with the intention of producing complete penetrate joints.Taguchi method
was used to prepare the experimentation design and statistical methods such as ANNOVA and regression
technique were employed to obtain optimized weld parameters. At 180 A Ip, 60 A Ib and 6 Hz frequency the
tensile and yield properties is better and the value are 185.55 Mpa and 156.62 Mpa respectively. This is due
to the fact that equiaxed dendrite structures can be observed during higher Ip and f.
