Abstract: With the development trend of large-leaf and lightweight in the wind power industry, composite extrusion plates have been widely used. In the face of the new structure of the multi-layer plate of the pultruded main beam, how to detect the perfusion defect between the pultruded main beam has become a new problem that nondestructive testing technicians need to solve. The ultrasonic detection method of the forming main beam of the extrusion plate in the wind power blade industry is studied. The results of conventional ultrasonic detection and phased array ultrasonic detection are compared, and a set of ultrasonic detection methods suitable for field use are summarised.
