In this investigation, AA2024 alloy was welded by tungsten inert gas welding. Access the influence of pitting corrosion on TIG weld; the joints were heat-treated after welding with different techniques. Moreover, the corrosion test was carried out with 3.5% NaCl solution under different pH values such as pH:5, pH:7, and pH: 12. From the experimental results, the joint treated with solution treatment with pH: 7 showed high corrosion resistance than its counterparts.
