A Review of Laser Welding For Bead Width and Weld Hardness

In today world the need for an optimized technique which can easily join two dissimilar materials in increasing day rapidly. Dissimilar joints are important because of both economic 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. The most challenging problem in various scenarios is real-time laser welding process of dissimilar materials. Various robust methods are being implemented time to time which can help in joining multiple materials simultaneously in different environments and conditions. Many efforts are being made for speeding up the process for the system to run faster and integrate into the system so that the process could be optimized for large scale. This paper focused on in depth literature review of the laser welding techniques used today.
