Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] The embodiment of the present invention provides an ultra-high-strength steel thin-walled spinning cylinder ultrasonic detection method, on the premise of the preparatory work of probe selection, including artificial defect comparison sample processing, initial sensitivity calibration, ultra-high-strength steel thin-walled cylinder The steps of cylinder scanning detection and defect location are described in detail below.
[0024] Preparations: Probe selection, the following aspects need to be considered:
[0025] (1) The detection frequency of the probe. Generally, the detection frequency of the probe should be the fixed frequency of each probe, which is determined according to the sound attenuation characteristics such as sound velocity and acoustic impedance of the material and state of the ultra-high-strength steel thin-walled spin...
