搅拌摩擦焊是一种固态焊接技术，适用于铝、铜等异种金属的焊接。由于通常不超过固相温度，与熔焊工艺相比，金属间相的形成可以减少。在搅拌摩擦焊接中，决定焊缝性能的金属间层厚度受焊接温度的影响，其形成符合Arrhenius定律。它通常在几百纳米厚的范围内。反过来，工艺温度是由工艺参数决定的，主要是机床的转速和进给速度。本研究将温度控制搅拌摩擦焊接技术应用于铝和铜的搭接接头。为了评估焊接界面附近温度-时间分布的影响，进行了不同焊接速度和探头长度的焊接实验。通过拉伸剪切试验、光学显微镜和扫描电镜对接头进行了研究。
Friction stir welding is a solid‐state welding technology, which is suitable for joining dissimilar metals such as aluminium and copper. Because the solidus temperature is typically not exceeded, the formation of intermetallic phases can be reduced when compared to fusion welding processes. In friction stir welding, the intermetallic layer thickness, which determines the seam properties, is influenced by the welding temperature and is formed in correspondence with the Arrhenius law. It is typically in the range of a few hundred nanometers thick. In turn, the process temperature is determined by the process parameters, primarily the rotational speed and the feed rate of the machine tool. In this study, a temperature‐controlled friction stir welding process has been applied to lap joints of aluminium and copper. Welding experiments with various welding speeds and probe lengths were performed in order to assess the effect of the temperature‐time profile near the welding interface. The joints were investigated by tensile shear tests as well as optical microscopy and scanning electron microscopy.
