中文摘要：
针对复合结构件焊缝熔深无损检测技术需求,分析密集焊缝熔深超声检测的主要原理,并建立检测系统;通过对密集焊缝熔深检测试验数据对比分析,实际检测结果表明,采用超声波检测方法对该密集焊缝熔深进行检测是可行的,且系统稳定可靠,实现了对复合结构件密集焊缝熔深检测。
英文摘要：
In view of the need of composite structural weld penetration nondestructive detection technology,analysis of the main principle of ultrasonic detection of weld penetration dense,and the establishment of detection system are described. Based on the analysis of the dense weld penetration testing data,the results show that by using ultrasonic method to detect the dense weld penetration is feasible,and the system is stable and reliable,has realized the detection of the dense weld penetration of composite structure.
