The effect of laser power, welding speed and beam incident angle on the butt weld bead geometry, i.e. depth of penetration (DOP) and bead width (BW) is investigated. The Keywords: experiment is designed based on three level Box-Behnken design with replication. Modeling of laser Laser welding welding of stainless sheet butt joint is performed using backpropagation trained neural network. The Neural network predicted results of the research showed a comprehensive and usable prediction of the laser welding Stainless steel parameters for butt joints using neural network. Modeling
