在压力容器定期检验中 ,焊缝内部一般用 X射线及超声波探伤。在实际应用中 ,超声波探伤比 X射线探伤更受欢迎。射线照相在辨别体积型缺陷时非常有效 ,而超声波可用于探测平面型和体积型两种类型缺陷。在节约资金和提高检测效率方面 ,超声波探伤优于射线探伤。焊缝表面的检测 ,
Periodic inspection of the pressure vessel, the weld internal generally X-ray and ultrasonic flaw detection. In practical applications, ultrasonic flaw detection is more popular than X-ray flaw detection. Radiography is very effective in identifying volumetric defects, while ultrasound can be used to detect both planar and volumetric types of defects. In terms of saving money and improving detection efficiency, ultrasonic flaw detection is better than radiographic flaw detection. Weld surface testing,
