铝合金搅拌摩擦焊在NASA的研究与应用

Research and Application on Friction Stir Welding of Al Alloy in NASA

概述了美国NASA航天铝合金及其焊接技术的研发历史和发展历程,详细介绍了当前主流先进焊接技术——搅拌摩擦焊的研究进展以及在Ares、Delta、SLS等典型型号中的应用现状,可为我国航天铝合金焊接技术的发展与应用提供有益借鉴。

As an aerospace research organization, National Aeronautics and Space Administration(NASA) of United States has been making progress in development of aluminum alloy and welding techniques used in space vehicle since the middle of last century. The article, by brief introduction of friction stir welding and its variants as well as its application on Ares, Delta and Space Launch System in NASA, intends to provide reference and inspiration for aerospace aluminum alloy welding in China.
