With the rapid development of wind power industry, wind power forging as one of the key components, its quality and performance have an important impact on the overall efficiency and stability of wind turbines. Ultrasonic inspection and quality control is the key link in the production of wind power forging, which is of great significance to improve product quality and production efficiency. This paper will introduce the ultrasonic testing and quality control of wind power forgings, in order to provide reference for related enterprises and researchers.
Principle of ultrasonic detection
Ultrasonic detection is a method to detect the surface and internal defects of materials through the reflection and attenuation of high-frequency sound waves based on the physical characteristics of sound waves propagating in materials. In wind power forgings, ultrasonic detection can effectively detect cracks, pores, inclusions and other defects in the material, and check the surface quality of the forgings to avoid surface scratches, pits and other problems affecting the performance of wind power equipment.
Ultrasonic testing method
The ultrasonic detection of wind power forgings generally adopts pulse reflection method, through the instrument to emit a certain frequency of ultrasonic wave and receive its reflected wave, according to the amplitude and phase of the reflected wave to detect the internal defects of the forging. In general, different parts of the forging have different ultrasonic reflection effects, so it is possible to judge whether there are defects inside the forging by observing the change in the reflected wave. At the same time, according to the difference in the propagation speed of ultrasonic waves of different frequencies in the material, the forgings can be targeted for detection.
Quality control process
The quality control process of wind power forging includes the following links:
Incoming material control: strictly control the procurement of raw materials to ensure that the quality of raw materials meets the requirements.
Production process: Develop a reasonable production process and carry out strict process control to ensure that each link in the production process meets the process requirements.
Storage environment: Reasonable storage and custody of forgings to ensure that they are not damaged during storage.
Quality testing: The use of non-destructive testing, hardness testing, chemical composition testing and other means to carry out a comprehensive test of wind power forgings to ensure that product quality meets expectations.
Acceptance of finished products: strict quality acceptance of finished products to prevent unqualified products from entering the market.
Quality control technique
Non-destructive testing: non-destructive testing technology is the use of sound waves, electromagnetic waves and other means to carry out comprehensive testing of forgings without damaging the forging. Through non-destructive testing technology, cracks, pores, inclusions and other defects in forging can be found effectively to ensure product quality.
Hardness testing: hardness is an important indicator to measure the wear resistance and pressure resistance of materials. The hardness testing of wind power forgings can effectively understand its hardness and strength and other properties, so as to ensure that it has good durability during use.
Chemical composition testing: Chemical composition is one of the key factors determining material properties. Through the chemical composition detection of wind power forgings, the chemical composition content can be understood, so as to ensure its excellent performance.
conclusion
Ultrasonic testing and quality control of wind power forgings are of great significance to improve product quality and production efficiency. By establishing perfect quality control process and adopting advanced quality control technology, the quality and reliability of wind power forgings can be effectively guaranteed, thus providing a strong guarantee for the stable operation of wind power equipment. In the future development, with the continuous growth of the wind power industry and the continuous improvement of the quality requirements for wind power forgings, ultrasonic testing and quality control technology will play a more important role in the production of wind power forgings. Therefore, relevant enterprises and researchers should further increase investment and actively explore and study more advanced ultrasonic detection and quality control technology to meet the development needs of the wind power industry.
