金属管棒材的无损探伤是保证金属材料质量的可靠手段。目前一般采用超声波探伤,但速度较慢。上海有色金属研究所和上海铜厂研制的 WTS—100型宽频带快速涡流探伤方法及设备,取得的成果是,在国内首次研制成功频率为1～100千周的宽频带涡流 Non-destructive testing of metal pipe and rod is a reliable means to ensure the quality of metal materials. The current general use of ultrasonic testing, but slower. Shanghai Institute of Nonferrous Metals and Shanghai Copper Works developed WTS-100 broadband rapid eddy current testing methods and equipment, the result is that in the country for the first time the successful development of a frequency of 1 to 100 weeks of broadband swirl
