摘要： A method of adjusting flaw detection sensitivity on an array ultrasonic probe comprises disposing a plate material P1 oppositely to the ultrasonic probe such that an upper surface of the plate material is disposed to be approximately parallel to an array direction of the transducers 11, or disposing a tubular material P2 oppositely to the ultrasonic probe such that an axial direction of the tubular material is disposed to be approximately parallel to the array direction of the transducers. Ultrasonic waves are transmitted from each transducer toward the upper surface of the plate material or an outer surface of the tubular material, and echoes are received from the bottom surface of the plate material or an inner surface of the tubular material on each transducer. Flaw detection sensitivity of each transducer is adjusted to substantially equalize intensity of an echo received on each transducer.

摘要： Ultrasonic testing on a part includes scanning the part while performing pulse echo and through transmission ultrasonic testing on the part; converting pulse echo data into time of flight (TOF) and amplitude channels, and converting through transmission data into a data representation that identifies porosity. The testing further includes analyzing the pulse echo TOF to identify locations of any anomalies in the part, and using loss of back (LOB) at each of the identified locations to discriminate low porosity from other anomalies.

摘要： In view of the fact that, when backup roll bearings which have been found satisfactory in the purity thereof in the sample evaluation through observations using a microscope are checked many times for the top surface layer portions of the raceway surfaces thereof according to an ultrasonic detecting method, on quite rare occasions, there can be found a bearing which contains one or more inclusions each having a size of as large as several hundreds mum, and such inclusions give rise to occurrence of a short-life bearing as a finished product, a range expressed by 2% Da depthxraceway surface is used as a test piece volume and the size of a non-metallic inclusion existing in the test piece volume is restricted to a length less than 500 mum, preferably, less than 100 mum. Here, the term "2% Da depth" means a depth up to 2% of a rolling element mean diameter from the surface of an inner or outer race of a bearing.

摘要： An inspection device inspects a joint-type outer joint member of a constant velocity universal joint that includes a cup section having a bottomed cylindrical shape and track grooves in an inner periphery thereof for torque transmitting elements, and a shaft section extending from a bottom of the cup section. The inspection device inspects the outer joint member, which is obtained through melt-welding on a cup member forming the cup section and a shaft member forming the shaft section. The inspection device includes a surface inspection unit to inspect for a defect which appears on a surface of the outer joint member due to welding, an internal inspection unit to inspect for an internal defect of a welded portion, and a recording unit to record an inspection result of the inspection. The inspection device is configured to efficiently perform in-line total inspection for the melt-welded joint-type outer joint member.
