介绍了军用飞机航空修理中现有焊接技术的缺陷以及搅拌摩擦焊(FSW)的发展现状。提出了FSW技术在军用飞机航空修理中的应用设想,并进行了可行性分析,初步探索了针对军用飞机裂纹、破孔和缺口等损伤形式的FSW修理应用前景。最后指出FSW技术在军用飞机航空修理中大规模推广应用需解决的几个问题。
The defect of the existing welding technology in aviation repair of military aircraft and the development of friction stir welding (FSW) are introduced. The application of FSW technology in the aviation repair of military aircraft was put forward and feasibility analysis was carried out. The application prospect of FSW repair in the form of damage, such as crack, hole breakage and notches, was initially explored. At last, it points out several problems to be solved in the large-scale popularization and application of FSW technology in the aviation repair of military aircraft.
