The modern and eco-friendly friction stir welding (FSW) method allows the combination of even such materials that are considered to be non-weldable. The development of FSW technology in recent years has allowed a rapid increase in the understanding of the mechanism of this process and made it possible to perform the first welding trials of modern polymeric and composite materials, the joining of which was previously a challenge. The following review work focuses on presenting the current state of the art on applying this method to particular groups of materials. The paper has been divided into subchapters focusing on the most frequently used construction materials, with particular emphasis on their properties, applications, and usage of the FSW method for these materials. Mechanisms of joint creation are discussed, and the microstructure of joints and the influence of material characteristics on the welding process are described. The biggest problems observed during FSW of these materials and potential causes of their occurrence are quoted. The influence of particular parameters on the properties of manufactured joints for each group of materials is discussed on the basis of a wide literature review.
现代且环保的搅拌摩擦焊（FSW）方法能够将那些被认为不可焊接的材料组合在一起。近年来，FSW技术的发展使得人们对这一工艺的机理有了快速深入的理解，并使得现代聚合物和复合材料的首次焊接试验得以进行，而此前这些材料的连接一直是个难题。以下综述工作着重介绍将该方法应用于特定材料组的当前技术水平。本文分为几个子章节，重点关注最常用的建筑材料，特别强调它们的性能、应用以及FSW方法在这些材料上的使用情况。讨论了接头形成的机理，描述了接头的微观结构以及材料特性对焊接过程的影响。列举了这些材料在搅拌摩擦焊过程中观察到的最大问题及其出现的潜在原因。基于广泛的文献综述，讨论了每组材料中特定参数对所制造接头性能的影响。
