Abstract:

In today world the need for a optimized technique which can easily join two dissimilar materials in increasing day rapidly. Dissimilar joints are important because of both economical and technical aspects, because a satisfactory service can be provided in cost reduction and performance by these joints. The demand for such joints in industry is huge. So, the study of dissimilar material welding is of a great interest for many of the researchers. In the paper work two dissimilar materials namely 1020 Mild steel and AISI 1552 were used in configuration of lap joint for laser welding. The process parameters are Laser Power, Scan Speed and Pulse Frequency at four levels were taken for the optimization process. Two response parameters namely weld hardness and Bead width was considered for different combinations of process parameters. Laser power and Frequency was found most effective parameters. The predicted values by the model were fairly close to the observed, which indicates that the model can be used to predict the values of responses within the range of parameter studied.
