Abstract

This paper investigates the comparative study on dissimilar joints of Incoloy 825 Ni-based alloy and AISI 316L steel. The paper explores process parameters such as laser focal diameter, strength, and pulse frequency of the above dissimilar plates in LBW welding. In order to explain the microstructural changes during welding, characterization was carried out by optical microscopy and electron microscopy. In order to study the transformation of mechanical properties in solder joints, micro-hardness and tensile tests are performed. Based on the research work, due to its less heat affected area, high power strength, and high repetition rate, laser beam welding has some advantages over other welding techniques. The Taguchi method is more efficient for predicting the outcomes among different analytical and experimental optimization methods. Therefore, this experiment demonstrates that different metals' welding efficiency can fulfil the oil and gas sector standards and other industrial sectors
