摘要

搅拌摩擦焊(FSW)是一种能够快速可靠地生产高质量接头的固态焊接方法。本文主要研究了Al6061-T6和SS304微摩擦搅拌焊接的多响应优化问题。刀具转速(TRS)和刀具横移速度(TTS)等焊接参数对异种焊接接头的力学响应有显著影响。为了确定最优工艺参数对异种焊接接头的极限抗拉强度(UTS)、显微硬度(MHV)和表面粗糙度(Ra)等力学响应的影响，采用与理想解相似偏好排序的多属性优化方法(TOPSIS)，试图找出可能的最佳工艺变量集。结果表明，采用TOPSIS方法可以改善搅拌微摩擦焊缝的多重响应。

Multi-attribute Optimization of Weld Parameters for Micro-friction Stir Welded Al6061/SS304 Sheets Using TOPSIS Approach

Friction stir welding (FSW) is a solid-state welding approach that can produce high quality joints in a fast and reliable manner. The present study is focused on optimization of multi-responses for micro-friction stir welded Al6061-T6 and SS304 sheets. Weld-parameters such as tool-rotational speed (TRS) and tool-traverse speed (TTS) influenced the mechanical responses of dissimilar welded joints significantly. In order to determine the effect of optimum process parameters on mechanical responses such as ultimate-tensile strength (UTS), micro-hardness (MHV) and surface-roughness (Ra) of dissimilar welded joints, an attempt has been made to find out the best possible set of process variables through multi-attribute optimization using technique for order of preference by similarity to ideal solution (TOPSIS) approach. Finally, the optimal solution shows that multi-responses of micro-friction stir welds can be improved through TOPSIS approach.
