incomplete penetration

Analyzing the stressed area of steel truss framework and selecting reasonable testing methods and parameters were effective for testing incomplete penetration by ultrasonic signals.

基于钢桁架的特殊结构，通过对其受力区域的分析及各种检测方法和参数的合理选择，利用超声波对未焊透所产生的物理信号进行评定和检测是有效的方法。

It is found that the ultrasonic imaging technology is an effective way to evaluate the quality of the ultrasonic brazed joint of aluminum matrix composites and detect the defects such as blow hole, oxide film inclusion and incomplete penetration in brazing interface.

超声成像技术能反映出铝基复合材料钎焊界面的接合状态，可检测出气孔、氧化膜夹杂和未钎透缺陷，为铝基复合材料钎焊的研究提供了有效的检测手段。

By these solutions, the incomplete penetration welded defection can be eliminated completely.

试验验证这些工艺方案完全能够消除未焊透缺陷.
