Abstract : The Aluminum alloys are the materials that are often used in automotive, aviation, and energy generation sectors. They are mainly used as they have high ratio of their strength to weight and also their weight is very less. These properties help to decrease the amount of fuel consumed and improve the economy of the products. Fusion welding has many problems such as porosity, solidification shrinkage, residual stresses. These issues can be mitigated by employing solid-state processes like Friction Stir Welding (FSW), which is also well suited to fabricate aluminum products. Tool geometry, speed of welding, and speed of tool determine the effectiveness and quality of the weld. This paper inspects and compares the different tensile strengths of various specimens made of the aluminum alloy AA8011 before and after corrosion. This study incorporates the Linear Radial basis function (LRBF) model to plot and understand the data. The study found that the specimens subjected to a welding speed (WS) of 45 mm/min, shoulder diameter (SD) of 21 mm, and tool rotation speed (TRS) of 1200 rpm yield the maximum tensile strength of the specimens before and after corrosion.
