Abstract :
The different modes of molten metal transfer
makes up a critical aspect of welding behavior which
significantly affects weld quality, so having basic
understanding of the fluidity behavior of the molten
weld metal will help Fabrication experts to produce
weld structures with optimal strength and quality. In
this present work, the Expert analysis of TIG molten
weld metal fluidity using the Bond dimensionless
Number was achieved. An expert experimental design
was done generating 30 sets of experimental runs
considering current voltage wire diameter and wire feed
rate and the bond dimensionless number as response.
The second order quadratic model was developed
employing the response surface methodology. A model
having 89% coefficient of determination and p-value of
< 0.0001. The result obtained showed that current has a
very significant effect on the bond number indicating
that a higher current will minimize the bond which
translates into an improved fluidity of the TIG molten
weld metal.
