轴类锻件的缺陷,可以分为外部缺陷和内部缺陷。对于内部缺陷迄今为止采用超声波探伤的方法是最为适用的。 (本文就是超声波探测轴类锻件内部缺陷的一点体会。)大型锻件和中小型锻件在探伤方面各有其特点。我们探伤的轴类是直径在100毫米至1米左右的。对于这样直径的轴类,在保证一定 Shaft forgings defects, can be divided into external defects and internal defects. So far the method of ultrasonic flaw detection is the most suitable for internal defects. (This article is the ultrasonic probe shaft forgings internal defects a little experience.) Large forgings and small forgings have their own characteristics in the testing. We test the shaft diameter is about 100 mm to 1 m. For such diameter shaft class, to ensure a certain
