چکیده مقاله
In this research, AA2024 T4 and AA6061 T6 alloys were connected to one another through TIG welding Experiments were performed with and without filler metal Sn 5 3Ag 4 6Bi under a flow of argon gas at 20 L/min over the connected workpiece Cross sectional surface of the Joint was etched with a solution containing 1 5 mL of HCl, 5 5 mL of NHO3, 1 mL of HF, and 95 mL of distilled water Based on the results of imaging, application of the eutectic mixture of Sn 5 3Ag 4 6Bi at the Joint site was found to limit the formation of hot cracks at the site The use of Ag containing compounds at the Joint of the Cu containing aluminum alloys was found to attenuate the risk of brittle grain boundaries in the heat affected zone HAZ due to the formation of brittle compounds In absence of the filler metal, for the AA2024 T4 alloy, the brittle phase of the Al2Cu compound was identified along the boundaries of the aluminum grains,indicating that the HAZ structure was susceptible to grain boundary cracking
