Ultrasonic detection method of wind turbine blades
1 Scope
This document specifies the general requirements, inspection procedures and requirements for contact ultrasonic pulse reflection/penetration testing of wind turbine blades:
Result processing:
This document applies to contact ultrasonic pulse reflection for internal defects in glass fiber or carbon fiber reinforced composite wind turbine blades
Method/penetration method inspection: This document can be used for main girder pultrusion and infusion molding processes: Main girder prepreg process and hand lay-up process
For higher porosity, ultrasonic testing can refer to this document, but the influence of acoustic characteristics needs to be considered:

3 Terms and Definitions
GB/T 17646, GB/T 2900:53, GB/T 12604:1 and the following terms and definitions apply to this document:
3:1
Ultrasonic pulse-echocontact testing
Using the contact method, according to the reflection echo generated by the discontinuity and (or) the bottom surface of the material when the ultrasonic wave propagates in the workpiece:
backwall echo to inspect for flaws or to assess material:
3:2
Penetrating method
Two probes are used, placed on opposite sides of the workpiece, one emits ultrasonic waves and the other receives ultrasonic waves: After penetrating the workpiece according to ultrasound
