ULTRASONIC INSPECTION DEVICE, ULTRASONIC INSPECTION METHOD AND JOINT BLOCK MATERIAL MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic inspection device and the like which more largely expand a detectable range even for a detection object containing an ultrasonic inhibition part.;SOLUTION: An ultrasonic inspection device 10 is a device to perform ultrasonic flaw detection for a block material 2 internally having an ultrasonic inhibition part 5 and including a joint surface P, an opposed surface facing the joint surface having no side contacting the joint surface and three or more not-opposed surfaces each of which has a side contacting the joint surface with the ultrasonic inhibition part, and the inside of a joint block material 1 having another member 3 jointed to the joint surface. The device includes: at least one main probe 11 constituted to transmit ultrasonic waves from a first surface which is one surface predetermined among at least the non-opposed surfaces; drive element control means 14 which can set information on a range where direct flaw detection can be performed by using ultrasonic transmission/reception means from the first surface and the area out of the range; and an auxiliary probe 12 for setting a propagation route so that the ultrasonic waves are oriented to the area out of the range or a delay time calculation part 142.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
