In today's dynamic changing environment, for industries to remain internationally competitive, traditional manufacturing techniques used for welding have to become more flexible and intelligent to attain better adaptability and higher productivity. In industrial applications of MIG/MAG welding processes, various types of shielding gases are used based on type of work material and weld quality required. In this proposed research, experimental studies will be conducted on welding productivity by using different shielding gas combinations. The aim of this project is to conduct experimental analysis on weld arc phenomenon, weld pool behavior, and weld quality and to build an intelligent system for the selection of optimum combination shielding gas mixtures. In addition this study also aims to examine how the microstructure and mechanical properties of different welds are influenced by the use of different shielding gases combinations.

在当今动态变化的环境中，为了保持行业的国际竞争力，用于焊接的传统制造技术必须变得更加灵活和智能，以获得更好的适应性和更高的生产率。 在MIG/MAG焊接工艺的工业应用中，根据工件材料的类型和所需的焊接质量，使用各种类型的保护气体。 在这项拟议的研究中，实验研究将进行焊接生产率通过使用不同的保护气体组合。 本项目的目的是对焊接电弧现象、熔池行为和焊接质量进行实验分析，并建立一个智能系统，用于选择最佳组合的保护气体混合物。 此外，本研究还旨在研究不同保护气体组合的使用对不同焊缝的显微组织和力学性能的影响。
