随着电磁学的发展,各种依据电磁原理的无损检测方法得到了越来越多的应用。常用的电磁无损检测如涡流探伤,磁粉探伤等都具有操作简单,检测费用低,探伤灵敏度较高等优点。但由于各有其检测特点,在无缝管生产线上的应用都受到一定的限制。而具有快速的特点的漏磁探伤装置在目前是较为理想的检测手段,是保证产品质量,提高经济效益的有利措施。 With the development of electromagnetics, a variety of nondestructive testing methods based on electromagnetic principle have been applied more and more. Commonly used electromagnetic nondestructive testing such as eddy current testing, magnetic particle inspection, etc. have the advantages of simple operation, low detection costs, higher detection sensitivity. However, due to their respective testing characteristics, the application of seamless tube production line are subject to certain restrictions. The fast magnetic flux leakage testing device is an ideal detection method at present, which is an advantageous measure to ensure product quality and improve economic efficiency.
