Abstract
The requirement to combine different materials is becoming more and more common in many industries, which means that new welding techniques must be developed or old ones must be improved. These developments have to serve a variety of uses, ranging from small assembly to large earth-moving equipment. Iron and aluminum-based alloys stand out among these materials because of their adaptability and ability to be used to create more useful and sustainable goods. But engineers continue to face difficulties when it comes to welding these metals together. Even though there are several ways to join these different metals together, no trustworthy or widely accepted welding process has been developed for industrial usage, especially when taking into account infrastructure, quality, cost, and human resources. This paper reviews recent studies on the joining of dissimilar materials, specifically focusing on laser welding. It examines three key experiments: "Dissimilar Metals Laser Welding between DP1000 Steel and Aluminium Alloy 1050" by Antonio B. Pereira et al. (2019), "Optimization of Process Parameters in Laser Welding of Dissimilar Materials" by Asit Behera (2020), and "Parameter Optimization and Mechanism of Laser–Arc Hybrid Welding of Dissimilar Al Alloy and Stainless Steel" by Ming Gao (2014). The review examines how welding circumstances affect the development of microstructure, intermetallic formation, mechanical properties, and joint applications. Tensile tests, hardness tests, and heat-affected zone (HAZ) analysis are all part of the quality assessment process. In order to meet the review's goals, the study also covers the optimization of welding parameters using the Taguchi technique, Grey-Relational Grade, and Analysis of Variance (ANOVA), with a focus on laser welding. The goal of this thorough investigation is to improve the application and dependability of welding procedures for different materials in industrial settings.
