In this study, laser welding of aluminum AA5182 with AA5356 filler wire was carried out and the
formability of the weld joint was evaluated through Erichsen test according to laser power, welding speed
and wire feed rate. Fracture was occurred in both directions, perpendicular and parallel to the weld line
at 0.75 of Erichsen ratio. Second order Regression model to estimate Erichsen ratio with experimental
variables was proposed and the performance of model was evaluated with F-test and average error rate.
