Problems solved by technology

But the problem is that the length of the focal area of ​​the focusing probe is limited, the detection thickness range is generally small, and the sensitivity outside the focal area drops sharply
During the detection process, the probe needs to be replaced frequently, resulting in a decrease in detection efficiency

The water immersion ultrasonic phased-array detection device comprises a flaw detection water tank (1), a rotary table (2), a control cabinet (3), a three-dimensional moving device (4), an ultrasonic flaw detector, a control computer (6), a probe clamp (7) and an ultrasonic probe. The device is characterized in that the ultrasonic flaw detector is an ultrasonic phased-array flaw detector (5), and the ultrasonic probe is an annular-array ultrasonic phased-array probe (8). The detection method comprises detection steps as follows: system connection is conducted; and ultrasonic echo signals are acquired and recorded. According to the device and the method, the probe is prevented from being changed repeatedly, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of non-destructive testing, and relates to a water immersion ultrasonic phased array testing device and a testing method for aero-engine disk parts. Background technique [0002] The turbine disk is an important key hot-end component of an aero-engine. With the development of high thrust-to-weight ratio and high power-to-weight ratio engines, higher requirements are put forward for the strength, toughness, fatigue performance, reliability and durability of the turbine disk. Most disks, especially some high-temperature alloy disks, need to work under high temperature and high load, which requires them to have the ability to maintain high performance under harsh conditions. However, due to the sensitivity of the material itself to defects, the existence of small defects such as inclusions will seriously affect the safety of the disk. Reliable detection of small-sized inclusion defects is the key to the safe and reliabl...
