研究通过对使用同种工艺、同种焊接材料焊接的铝热焊接头进行焊后正火处理,并对比正火接头与未经热处理接头的性能差异,探讨铝热焊接头焊后正火热处理对接头性能的影响,为改善高速铁路铝热焊接头性能打下理论基础。
Through the use of the same kind of technology, the same welding materials welded aluminum heat welding after normalizing after welding, and compared the performance of normal joint and non-heat treated joints to explore the aluminum welded joints after normalizing heat treatment Joint performance, to improve the performance of high-speed railway aluminum heat welded joints laid the theoretical foundation.
