Recent Advances in Material Sciences, Lecture Notes on Multidisciplinary Industrial Engineering, Metal joining process is an emerging technique in the manufacturing stream. Welding is the most preferred joining process in making similar or dissimilar metal joints. Many researchers helped in improving the characteristics of weldments. Gas tungsten arc welding (GTAW) is an arc-based welding process and continues to be one of the major welding processes used in the industry for high-quality joints. Lack of penetration is a major drawback for this GTAW, improving this may result in a wide range of applications. Activated TIG is a solution for producing deeper penetrations. This is achieved through the application of a thin coating of activating flux material onto the workpiece surface prior to welding. This work studies the influence of flux coatings in producing better deeper penetrations by applying A-TIG welding on Al-6082 and studies the joint strength and topology of weldments.
