利用超声将钢销钉插入的方法连接Al材,只用常规连接方法所需的部分成本和更低的重量即可造成一种极高性能的结构。美国马萨诸塞州Aztex公司研制出一种Z形销连接系统,据说不必进行机加工而且可用于制做特大型的零件。对于铝结构件,尤其是飞机工业和船舶工业,有着广泛的应用可能 The use of ultrasound to insert the pin into the Al material, using only part of the conventional connection method costs and lower weight can result in a very high performance of the structure. Aztex, Massachusetts, USA, has developed a Z-pin connection system that is said not to be machined and can be used to make very large parts. For aluminum structural parts, especially the aircraft industry and the marine industry, has a wide range of applications
