Abstract Details

2017, Master of Science, Ohio State University, Welding Engineering.
Fusion welding is one of the joining processes industries prefer to use in order to produce high quality and safe joints for a desired manufactured product to meet customer needs. Unfortunately, sometimes fusion welding process is not applicable for some of the high strength materials and applying this type of join processes can lead to a solidification cracking due to material wide solidification temperature range. This issue pushes the designers to use different types of joining processes instead of fusion welding such as riveting or screws, which can be alternative solution for fusion welding. Using these processes instead of fusion welding can bring up even more problems for the joint such as material loss, increasing weight, corrosion, and high stress concentration. Therefore, improving the fusion welding process on one of the high strength and solidification crack susceptibility materials, like aluminum alloy 2024, will be the main goal of this study. Al alloy 2024 will be fusion welded autogenously, and material’s solidification crack behavior and microstructure will be investigated in this work by four different GTAW processes and they will be compared with a new weld technique never used before this study called; tandem GTAW side by side process with alternating working electrodes.
