协同双面搅拌摩擦焊接技术

Synergistically Double-Sided Friction Stir Welding

协同双面搅拌摩擦焊接(SDS-FSW)作为搅拌摩擦焊接技术的一种新的改进形式,显著改善了传统搅拌摩擦焊接变形大、焊接效率低等问题,对焊接质量也有提升作用,适用于大尺寸、大厚度的板材或型材的焊接。但目前SDS-FSW仍处于初始研发阶段,相关的理论及应用研究较少,研究成果主要集中在6061铝合金上。本文主要介绍SDS-FSW技术的发展历程、技术特点与典型研究结果及应用前景,以期为SDS-FSW技术的发展及实际工程推广提供参考。

Synergistically double-sided friction stir welding(SDS-FSW)is a significant variant of friction stir welding(FSW).The problems of large deformation and time-consuming of traditional FSW are greatly suppressed by SDS-FSW.SDS-FSW has prompted considerable scientific and technological interests due to its advantages in welding large-sized and thick plates or profiles.At present,the research and application of SDS-FSW are still in the initial development stage,and relevant research results are mainly limited to 6061 aluminum alloy.This paper provides an overview of this new technology,including its development history,technical characteristics,typical research results and application prospects.The aim is to provide a reference for the further development and engineering application of SDS-FSW.
