Pulsed laser beam welding Is a non-traditional technique for welding of a wide range of dissimilar metals. For optimizing parameters for welding of Permendur 49 with stainless steel-304, a detailed parametric study has been conducted using an industrial pulsed Nd :YAG laser. Effect of welding parameters on welds has been studied for controlling weld properties. Based on microscopic examination of simulated (bead-on-plate) welds on the constituents, an expert system has been developed. The expert system has been experimentally validated.
