摘　　要：雷达产品所用某组件壳体结构复杂,气密性要求高,采用了较为先进的电子束焊接,但在实际生产中其成品率较低,对电子束焊接的主要影响因素—配合间隙、扫描参数及点焊方法进行了详细的分析,并提出了改进电子束焊接方法的具体措施。实践证明所采用的电子束改进方法是成功的,对类似问题的解决提供了有益的参考。The digital assemblies are widely used in radar system. But it has a complicated shape and needs high airproof performance in many cases, so it＇s sealed by advanced EBW. The yield is very low in the manufacture. The emphasis is on the main technology factors of cooperated clearance, the scan parameters and the techniques of spot welding, introduce the methods which are used to improve EBW techniques. These techniques have been put into practice and proved to be success. Therefore they can be available for reference.
