近二年来,上海地区冶金系统的无损检测技术发展很快,从事这方面工作的人员增长50％以上,仪器设备也有大幅度增加,目前已投入生产检验的已有二十几条无损检验生产线,承担着重要用途金属材料的质量检验任务,年检验量钢铁材料已比二年前增加一倍以上,有色材料已比二年前增加十几倍。检测方法也已由单纯采用超声波发展到超声、涡流、射线、磁粉、光电、气动等多种
In the recent two years, the non-destructive testing technology of the metallurgical system in Shanghai has developed rapidly. The number of personnel engaged in this field has increased by over 50% and the number of instruments and equipment has also risen sharply. At present, about 20 non-destructive testing production lines have been put into production inspection, Bear the important purpose of the quality inspection of metal materials, the annual test of steel materials has more than doubled more than two years ago, non-ferrous materials have increased more than ten times two years ago. Detection methods have also been developed from the simple use of ultrasound to ultrasound, eddy current, radiation, magnetic powder, photoelectric, pneumatic and other
