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.

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.
