采用相控阵超声检测技术开展活塞的内冷油道缺陷检测,检测实验结果表明,相控阵超声检测很好地解决了内冷油道的缺陷检测难题,检测结果图像化显示,大大降低了检测人员的技能要求,提高了检测效率,可进一步推广到自动化检测。
The phased array ultrasonic testing technology was used to detect the internal cooling oil passage defects of the piston. The experimental results show that the phased array ultrasonic testing can well solve the defect detection problem of the internal cooling oil passage. The test results are greatly reduced Detection of the skills of staff to improve the detection efficiency can be further extended to automated testing.
