由于鋁合金的强度較高,几乎近于鋼材,加上近年来高强度新型鋁合金的不断出現,鋁合金在工业上的应用大有逐步排挤鋼材之势。同时,近代焊接技术水平不断提高,使焊接接头质量日益改善,日益可靠,所以許多重要结构上广泛采用了焊接方法。这样,鋁合金焊接的研究,也就逐漸为各国焊接科学工作者所重視。 Due to the high strength of aluminum alloy, almost in the vicinity of steel, coupled with the continuous emergence of new high-strength aluminum alloy in recent years, the application of aluminum alloy in the industry has gradually crowded out the trend. At the same time, modern welding technology continues to improve, so that the quality of welded joints is increasingly improved, more and more reliable, so many important structures widely used welding methods. In this way, the research of aluminum alloy welding, also gradually attach importance to all countries of welding science workers.
