To study the influence of welding current on the welding quality of 5052 aluminum alloy TIG welding, the microstructure, mechanical properties and corrosion resistance of the welded joints obtained under different currents from 100 A to 120 A were discussed. The results showed that when the welding current is 100~120 A, with the increases of welding current, the strength of the welded joint (of 5052 aluminum alloy TIG) increases, while the plasticity decreases.
