Friction stir spot welding of dissimilar aluminum and copper sheets was investigated in details using Taguchi approach this study. Analysis variance conducted to identify the effective parameters their contributions on mechanical performance. The findings revealed that outputs followed normal distribution. results indicated rotational speed with contribution 87.7% most parameter maximum tensile...
Galvanic corrosion is an ever-present problem in all different environments, particularly in tanks. The goal of this project is to develop a finite element model that can be used with experimental data to characterize the corrosion of a galvanic weldments couple in an electrolyte. In this study sample are welded by gas tungsten arc welding and friction stir welding. According to ASTM G8, Evalua...
Friction stir welding is characterized as an ecological and low-cost process in comparison to traditional techniques, due its application the solid state, it a feasible option for joining similar and/or dissimilar materials. The present investigation seeks determine effect of friction welding’s parameters on corrosion resistance Al 6061-T6–Cu C11000 joint, with mathematical analysis validate re...
In this study, corrosion behavior of Ti-6Al-4V titanium alloy joint by friction stir welding with a rotational speed of 375 rpm and a travel speed of 100 mm/min was investigated. The welding procedure was carried out under β-transus temperature that was consisted of equiaxed grains in the stir zone. The corrosion behavior of the welded joint was investigated in 3.5% NaCl solution at temperature...
In this research, the effects of parameters include tool rotational and traverse speeds were investigated on heat generation and material flow during friction stir welding of Ti-6Al-4V alloy with computational fluid dynamics (CFD) method. Simulation results showed that with increasing of tool rotational and decreasing tool traverse speed, the more frictional heat generates which causes formatio...
