利用超声波来无损检测受检件的方法以及执行该方法的装置
摘要：
本发明涉及一种利用超声波来无损检测受检件(100)的方法，包括以下方法步骤：a.将定向超声波脉冲以入射角β射入受检件(100)之中，其中以电子方式调整入射角β；b.记录由入射到受检件(100)之中的超声波脉冲产生的回波信号；c.确定入射位置X0，在该入射位置处可以记录对应于受检件体积中的缺陷(102)的回波信号；d.确定缺陷(102)的ERS值在位置X0处变得最大的入射角β最大；e.将受检件(100)表面上的入射位置从X0变为X1，其中检测入射位置的变化；f.以电子方式调整入射角β，以使得缺陷(102)的ERS值在改变后的入射位置X1处最大。本发明还涉及一种用来执行该方法的装置。
摘要（英）：

The invention relates to a method for the non-destructive testing of a test object (100) by way of ultrasound, said method comprising the following steps: (a) radiating directed ultrasonic pulses into the test object (100) at an irradiation angle ss, said irradiation angle ss being set electronically, (b) recording echo signals that result from the ultrasonic pulses radiated into the test object (100), (c) determining an irradiation position X0 in which echo signals can be recorded that can be associated with an error (102) in the volume of the test object, (d) determining the irradiation angle ssmax for which the ERS value of the error (102) reaches its maximum at position X0, (e) changing the irradiation position X0 to X1 on the surface of the test object (100), the change of the irradiation position being captured, (f) electronically adjusting the irradiation angle ss in such a manner that the ERS value of the error (102) reaches its maximum in the changed irradiation position X1. The invention further relates to a device which is suitable for carrying out said method.
