搅拌摩擦焊（FSW）是一种相对现代的固态焊接工艺，已应用于航空航天、铁路、汽车和船舶工业，用于连接铝、镁、锌、钛、铜合金、异种金属和热塑性塑料。刀具转速、刀具横移速度、刀具倾斜角度等工艺参数对焊接质量有重要影响。研究了FSW工艺对AA2124/SiC/25p金属基复合材料（MMC）板拉伸性能的影响。结果表明，在刀具转速一定的情况下，增大刀具的横移速度会降低接头效率。本研究的第二个贡献是应用决策树技术预测搅拌摩擦焊接MMC板的拉伸性能。可以看出，这种方法的应用具有很高的准确性。DOI: http://dx.doi.org/10.5755/j01.ms.18.4.3092
Friction stir welding (FSW) is a relatively contemporary solid state welding process and has been employed in aerospace, railway, automotive and marine industries for joining of aluminum, magnesium, zinc, titanium, copper alloys, dissimilar metals and thermoplastics. The FSW process parameters such as tool rotation speed, tool traverse speed and tilt angle play an important role in deciding the joining quality. The present study defines the effect of FSW process on the tensile properties of the AA2124/SiC/25p metal matrix composite (MMC) plates. Obtained results showed that the joint efficiency decreases by increasing the tool traverse speed while tool rotation speed was kept constant. Second contribution of this study is the application of decision tree technique to predict the tensile properties of friction stir welded MMC plates. It is seen that methodology can be applied with great accuracy. DOI: http://dx.doi.org/10.5755/j01.ms.18.4.3092
