The principles of the friction welding (FW) process of the two different non-ferrous metals, aluminum and copper, are presented in this paper. Considering that the bimetallic Al-Cu joints find applications in electrical engineering, as well as in other industrial fields, the basic characteristics and compatibility of these metals are discussed, along with the influence of various parameters on the properties of their friction welded joints. The experimental study involved rotation friction welding (RFW), which was used to weld aluminum and copper samples. The samples were monitored for shortening due to the applied deformation, as well as the size of the formed mushroom. Then, the central part of the welded joint was cut from the welded samples to determine the hardness and microstructure of the joint. At the end of the research, the possibility of applying software for the design of a numerical model for analysis of the possibility of joining aluminum and copper, with the same input parameters as those used in the experiment, was considered. The numerical simulation exhibited a high agreement with the experimental results.
本文介绍了两种不同有色金属铝和铜的摩擦焊接（FW）工艺原理。考虑到铝铜双金属接头在电气工程以及其他工业领域的应用，讨论了这些金属的基本特性和兼容性，以及各种参数对其摩擦焊接接头性能的影响。实验研究采用旋转摩擦焊接（RFW）来焊接铝和铜样品。监测样品因施加变形而产生的缩短情况以及形成的蘑菇头尺寸。然后，从焊接样品上切下焊接接头的中心部分，以确定接头的硬度和微观结构。在研究结束时，考虑了应用软件设计数值模型的可能性，该模型用于分析在与实验相同的输入参数下连接铝和铜的可能性。数值模拟与实验结果高度吻合。
