Metal Inert Gas (MIG) welding is pivotal in industrial applications due to its efficiency and quality,
with solidus temperature critically influencing weld integrity. This study investigates the effects of
current (240–270 A), voltage (23–26 V), and wire feed rate (2.4–3.0 mm/s) on solidus temperature
of mild steel metal plate, integrating experimental data, Response Surface Methodology (RSM), and
an Artificial Neural Network (ANN) to develop predictive models. Experimental results revealed
