Abstract Friction-based welding processes are considered as very efficient solid-state metal joining processes due to soundness of the welded joint with remarkably less energy consumption and environmentally friendly. The terminology behind these processes is to make use of elevated temperatures caused by the mechanical friction at contacting surfaces to fuse materials together. Several different friction-based welding techniques are classified briefly explaining their mechanisms to show a comparison between friction welding (FRW) and friction stir welding (FSW). In FRW contact between the specimens itself induce friction, while FSW uses a non-consumable rotating tool to fuse material at the junction. Numerous advantages and drawbacks exhibited by both the processes are compared by overviewing the current researches. Also extensive focus on the various factors influencing the properties of FSW joints such as rotational speed, welding speed, axial force, tool geometry, and defects are studied. FSW displayed superiority in welded joints as regards adaption to modern technologies, optimized process parameters, and the ability to join a wide variety of dissimilar metals and alloys.

基于摩擦的焊接工艺：摩擦焊接和搅拌摩擦焊接

摘要 基于摩擦的焊接工艺被认为是一种非常有效的固态金属连接工艺，因为焊接接头质量好，能耗显着降低，而且对环境友好。这些工艺背后的术语是利用接触表面机械摩擦引起的高温将材料融合在一起。对几种不同的基于摩擦的焊接技术进行了分类，简要解释了它们的机制，以显示摩擦焊接 (FRW) 和搅拌摩擦焊 (FSW) 之间的比较。在 FRW 中，试样本身之间的接触会引起摩擦，而 FSW 使用非消耗性旋转工具在接合处融合材料。通过对当前研究的概述，比较了这两种工艺所表现出的众多优点和缺点。还广泛关注影响 FSW 接头性能的各种因素，如转速、焊接速度、轴向力、工具几何形状和缺陷。FSW 在焊接接头方面显示出对现代技术的适应性、优化的工艺参数以及连接各种不同金属和合金的能力方面的优势。
