Microstructural analysis of Nd:YAG laser welding for Inconel alloy

Nd:YAG Laser welding is the widely used in the welding process in which quality of micro welded area for assembly of small components mainly depends on the input parameters are Laser beam power, Welding speed and Frequency. By considering responses are microstructure for pre and post heat treated welding samples of the Inconel 625 alloy material. These work we are mainly focused on the microstructural analysis for before and post heated for welding samples, after post heat treatment of welding samples the welding area, parent metal and Heat affected zone are Slightly changes occurs on the microstructures of welded area and Heat affected zone for before post heat treatment of welding samples.
