本文采用焊接热模拟技术，模拟焊接热循环温度效应，研究了Ａｌ－Ｌｉ合金的热塑性特性和焊接热裂纹敏感性，发现Ａｌ－Ｌｉ合金具有与ＬＧ＿２铝相同或更良好的可焊性能。
In this paper, the welding thermal simulation technology was used to simulate the thermal cycling temperature effect. The thermoplastic properties of Al-Li alloy and the thermal cracking susceptibility of the weld were studied. It was found that Al-Li alloy has the same or better solderability as LG_2 aluminum.
