Abstract

This work is an attempt to select the optimum process parameters for friction stir welding of similar AA6061 aluminum alloy based on multiple criteria decision-making approach. The friction stir welding experiments have been conducted according to the orthogonal L9 array and the chosen input parameters are tool rotational speed, feed, and tilt angle. The responses measured are tensile strength, hardness, and % of elongation of welded joint. The multi-criteria decision-making technique namely multi-objective optimization based on the ratio analysis (MOORA) is used to find the optimum process parameters combination. The optimum conditions are tool rotational speed of 1120 rpm, feed of 30 mm/rev and tilt angle at 1 o.

基于MOORA的同类AA6061搅拌摩擦焊接工艺参数多目标优化

本工作是基于多准则决策方法选择同类AA6061铝合金搅拌摩擦焊接最佳工艺参数的尝试。采用正交L9阵列进行搅拌摩擦焊接实验，输入参数为刀具转速、进给量和倾斜角度。测量的响应是焊接接头的抗拉强度、硬度和伸长率。采用多准则决策技术，即基于比率分析的多目标优化(MOORA)，寻找最优工艺参数组合。刀具转速为1120转/分，进给量为30毫米/转，倾斜角度为1°。
