本文以研制0.8—1毫米LT—27型薄壁铝合金零件为基础,仅就产品的焊接接头结构设计、真空电子束焊接设备,产品密封焊接中的气孔问题,焊接工艺技术等,作了一些讨论。通过对国产、进口产品零部件的外观检查〔11〕解剖、金相检验、化学分析等进行了对比,产品质量赶上或超过了国外进口同类型产品的水平。生产实践证明:产品的真空电子束密封焊接方法的确定,设备的选择〔2〕
This article is based on the development of 0.8-1mm thin-walled aluminum alloy parts LT-27, only some of the product structure design of welded joints, vacuum electron beam welding equipment, product sealing problems in the pores, welding technology, made some discuss. Through the appearance of domestic and imported parts of the product inspection (11) anatomy, metallographic examination, chemical analysis were compared, product quality to catch up with or exceed the level of foreign imports of the same type of product. Production practice has proved that: product vacuum electron beam sealing welding method to determine the choice of equipment 〔2〕
