Application of Laser in Mechanical Engineering

Application of LASER in Mechanical Engineering Process and application of LASER involving heating and cooling under the controlled conditions of a material to obtain certain desirable properties is known as heat treatment. 1. Laser surface alloying        The different types of heat treatment process using laser are shown in the picture. In the process of annealing there is no zone affected by the heat and melting takes place only in the level of picometer thickness.         In hardening process there is a zone in the form of hemisphere which is affected by the heat. In this surface alloying method there
