Abstract

Objective: To study the influence of tungsten inert gas welding and friction sir welding on the mechanical properties and corrosion behaviour of AA5083-H321 weldments. Methodology: The received AA5083-H321 5 mm thick plates were welded by Tungsten inert gas welding (TIG)and friction stir welding(FSW) at optimized process parameters discovered in previous research work. Corrosion tests ASTM G66 and ASTM G67 as specified by ASTM 928M standards for marine service was performed for study the corrosion behaviour of the weld joints. Findings: It was found that TIG weldments are more susceptible to exfoliation and intergranular corrosion than FSW weld samples, and parent substrate. Novelty/ Improvement: The adoption of friction stir welding in ship building industries can further reduce the corrosion occurred in ship structures in service.
