摘要
介绍有关可焊铝锂合金焊接研究的进展。分析铝锂合金的可焊性、0 14 2 0合金的焊接、80 90合金焊接、Weldalite 0 49合金焊接方面的研究成果。铝锂合金焊接时 ,容易产生气孔、破裂和导致焊接系数降低 ,焊接前后采取适当的处理措施可以获得低气孔率、高强度的焊缝。
The investigations on welding of aluminum lithium alloys are introduced The researches of weldability of aluminum lithium alloys, 01420 alloy wielding, 8090 alloy wielding, Weldalite 049 alloy wielding are described In the welding of aluminum lithium alloys, pores, cracking are often produced and jointing coefficient is low, but the less pores and high welding strength welding line can be obtained if appropriate treatments are applied in pre and post welding
