摘要： PROBLEM TO BE SOLVED: To provide a method for inspecting a joined portion capable of accurately inspecting a joined portion by ultrasonic waves and reducing restrictions on the arrangement position of a probe.
SOLUTION: A first ultrasonic flaw detection is performed by emitting ultrasonic waves from a probe 40 of an ultrasonic flaw detection device to a bonding face between a second flange part 14B of an insert 14 and a top board part 12B of a component 12, and receiving reflected waves of the ultrasonic waves reflected by the bonding face to acquire an image of the condition of the bonding face. Next, a second ultrasonic flaw inspection is performed by applying a load to the insert 14 and removing the load to acquire an image of the condition of the bonding face. If there is a bonding defect, a load in a direction to separate is applied to the bonding face to make a gap in a portion with the bonding defect. Since the reflection waves from a normal bonding portion are different from the reflection waves from the portion with the gap, it is possible to specify the bonding defect portion from the image.

摘要翻译：要解决的问题：提供一种能够通过超声波精确地检查接合部的接合部的检查方法，并且减少对探针的配置位置的限制。解决方案：通过将超声波从超声波探伤装置的探头40发射到插入件14的第二凸缘部分14B与部件12的顶板部分12B之间的接合面进行第一超声波探伤并且接收由接合面反射的超声波的反射波，以获得接合面的状态的图像。接下来，通过向插入件14施加负载并移除负载以获得接合面的状态的图像来执行第二超声波探伤。如果存在接合缺陷，则在接合面上施加分离方向的负荷，从而在具有接合缺陷的部分产生间隙。由于来自正常结合部分的反射波不同于具有间隙的部分的反射波，因此可以从图像中指定接合缺陷部分。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic inspection method and an ultrasonic inspection method, capable of inspecting the inside of an inspection object, even when there are surfaces of the inspection object having irregularities or are made sloped.
SOLUTION: Ultrasonic waves are transmitted and received by a probe 10, thereby detecting a defect S or flaws of the inspection object 100. A focus-type probe is used as the probe, and the focal point F of the probe is set at a position of an object to be detected being beyond the downstream side of an ultrasonic transmission. The probe makes the ultrasonic waves expand and propagate radially inside the inspection object, whereby a defect inspection can be carried out by projecting the ultrasonic waves onto the defect S or the like existing inside the inspection object, even if the surface of the inspection object has irregularities or is made sloped. If the probe concurrently make the part operate transmission and reception, the defect position is easily specified. Similarly, the defect position is easily specified, by displaying an image obtained by received ultrasonic waves in at least two dimensions.

摘要翻译：要解决的问题：为了提供能够检查检查对象的内部的超声波检查方法和超声波检查方法，即使当检查对象的表面具有不规则性或倾斜时。解决方案：超声波由探针10传送和接收，从而检测检查对象100的缺陷S或缺陷。使用聚焦型探针作为探针，并且设置探针的焦点F 在被检测体的位置超过超声波传播的下游侧。探针使超声波在检查对象物内径向扩张扩散，由此即使检查对象的表面具有检测对象的表面，也可以将超声波投影到检查对象内部的缺陷S等上进行缺陷检查不规则或倾斜。如果探头同时使部件进行发送和接收，则容易指定缺陷位置。类似地，通过在至少两个维度上显示由接收的超声波获得的图像，容易指定缺陷位置。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a new feature amount measuring method of a texture variation section by ultrasonic wave capable of measuring the feature amount such as distribution or the like of hardness of the texture variation section by a non-destructive method using normalization processing without cutting or the like of an inspection object. SOLUTION: The feature amount of the texture variation section of the inspection object 100 is measured by transmitting the ultrasonic wave from a probe 7 to the inspection object 100 and receiving back scattered wave. Reference wave including the back scattered wave is previously received by a reference section. The back scattering intensity ratio is determined by dividing the signal received in the texture variation section by the reference wave and performing the normalization processing. A part of a predetermined hardness in the texture variation section is determined by measuring the depth of the predetermined back scattering intensity ratio corresponding to the predetermined hardness.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for detecting a texture change by an ultrasonic wave, capable of detecting reliably and clearly, for example, the texture change in a welded part, and the texture change by heat treatment, surface modification or the like.
SOLUTION: The texture change is detected by transmitting the ultrasonic wave from a probe to a testing body and by receiving a back-scattered wave. A reference wave f1'(t) including the back-scattered wave is received in a reference part of the testing body. An inspecting wave g1(t) received in the inspection part of the testing body is normalized by dividing it with the reference wave f1'(t) or by finding a difference between the inspecting wave and the reference wave. The reference wave and the inspecting wave may be a function of a time and a frequency characteristic value other than a function of the time and an amplitude. Normalized display may serve as B-scope display of a cross section. The method/detector detects the texture change in the welded part, and the texture change by the heat treatment, the surface modification or the like.
