Abstract In this experimental study, an attempt has been made to optimize the process parameters of friction stir welding (FSW) for tensile strength and percentage elongation using Taguchi-based gray relation analysis (GRA). An orthogonal array of L9 has been implemented to fabrication of joints. The experiments have conducted according to the combination of rotational speed, tool tilt (TLT) and types of tool pin profile (TPP). The results revealed that the rotational speed is most significant… CONTINUE READING
