随着冶炼、热处理等工业技术的不断发展,薄板钢件在电梯、起重机械等特种设备中运用越来越广泛,而特种设备的安全性对薄板的安全性能要求也越来越高。为了提高对薄板钢件超声波探伤的精度,对薄板进行有效及可靠的评估,本文研究并制作了针对探测板厚在3mm~8mm的薄板对接焊缝探伤的超声波双晶斜探头。1双晶探头的基本结构超场波双晶探头有两块压电晶片,一块用于发射超声波,另一块用于接收超声波,根据入射角的不同,分
With the continuous development of industrial technologies such as smelting and heat treatment, the application of thin-plate steel parts in special equipment such as elevators and cranes is becoming more and more widespread, and the safety of special equipment is demanding more and more on the safety performance of thin plates. In order to improve the accuracy of the ultrasonic flaw detection on the thin plate steel and to evaluate the thin plate effectively and reliably, this paper studies and produces the ultrasonic dipole probe for the flaw detection of the butt welds with the thickness of 3mm ~ 8mm. The basic structure of a dual-crystal probe Super-field dual-crystal ultrasonic probe has two piezoelectric chips, one for the emission of ultrasound, the other for receiving ultrasound, depending on the angle of incidence, points
