Abstract

AA6061-SiC composites are the most preferred materials for applications in the automobile and aerospace sector due to their superior properties. The FSW process is one of the novel solid states joining processes that overcome almost all the difficulties of the fusion welding process because the process that operates well below the melting point of the metals to be joined, consumes less energy, environment-friendly, and versatile, no shielding gas or filler metal is used. The welding parameters such as tool rotational speed, axial force, and tool pin profile play a major role in deciding the joint strength and hardness of the weld zone. Taguchi method was employed in this study to scrutinize the impact of welding processing factors, including rotational, speed, axial load, and pin profile on ultimate tensile strength, microhardness of weld zone. The results reveal that the welded joints produced at 750 rpm of tool rotational speed, the axial load of 6 kN using a square pin tool profile that exhibits higher UTS. The Vickers's hardness of AA6061-6 wt.% SiC composites was found to be superior at tool rotational speed of 900 rpm, the axial force of 6kN using cylindrical tool pin. The ANOVA Findings based on Vickers's hardness are tool profile: 53.84%, tool rotational speed: 20.16%, and axial force: 21.32%.

aa6061 - 6wt FSW参数优化% SiC复合板

AA6061-SiC复合材料由于其优越的性能，是汽车和航空航天领域应用的首选材料。FSW工艺是一种新型的固态连接工艺，它克服了熔焊工艺的几乎所有困难，因为该工艺的工作温度低于被连接金属的熔点，能耗低，环境友好，用途广泛，不使用保护气体或填充金属。刀具转速、轴向力、刀销轮廓等焊接参数是决定焊接区接头强度和硬度的主要因素。本研究采用田口法考察了旋转、速度、轴向载荷、销形等焊接工艺因素对焊缝区极限抗拉强度、显微硬度的影响。结果表明，在刀具转速为750转/分、轴向载荷为6 kN时，采用方销型刀具的焊接接头具有较高的UTS。维氏硬度为aa6061 - 6wt。在刀具转速为900转/分，轴向力为6kN的圆柱形刀销下，SiC复合材料的性能更优。基于维氏硬度的方差分析结果为:刀具外形为53.84%，刀具转速为20.16%，轴向力为21.32%。
