近些年来,随着航空航天的不断发展,对航天器材料的要求也越来越高,由于铝及铝合金密度小,强度好、易加工成型、弹性好、抗冲击性能好、耐腐蚀、耐磨、表面易着色、可回收再生等良好的物理化学性能,在航空航天工业中得到了广泛的应用。轻合金的广泛应用又促进了轻合金焊接工艺的发展,文章分别对铝及铝合金的钎焊,钨极惰性气体保护焊,熔化极惰性气体保护焊,搅拌摩擦焊,超塑成形/扩散连接进行了概述。
In recent years, with the continuous development of aerospace, the requirements for spacecraft materials are also getting higher and higher. Due to its low density, good strength, easy processing and forming, good elasticity, good impact resistance and corrosion resistance, Wear-resistant, easy to surface coloring, recyclability and other good physical and chemical properties, in the aerospace industry has been widely used. The wide application of light alloy has promoted the development of light alloy welding process. The article separately discusses the welding of aluminum and aluminum alloy, tungsten inert gas welding, melting inert gas welding, friction stir welding, superplastic forming / diffusion bonding An overview is given.
