摘要：
Pertaining on the present work on improving the corrosion resistance of AA 6063 aluminum alloy is found to weld with many backing plate materials like stainless steel, copper, marble and brass in accordance to the welding process that inherits itself with TIG. Utilizing the Orthogonal array L16, experiments were carried out. The corrosion resistance was improved by optimizing the pulsed TIG welding process parameters like current (A), gas flow rate (B), backing material (C) and backing thickness (D) using Genetic Algorithm (GA). Results proved that the GA shows a better corrosion resistance rate that was obtained to about 0,0408 mm/year with the backing material as copper. © 2019, Faculty of Metallurgy. All rights reserved.
