Abstract:
In order to solve the problem of weld penetration measurement at the head of gas generator in liquid rocket engine, the phased array ultrasonic testing technology was studied.The principle of penetration measurement was described according to the welding structure characteristics of generator head.Through the inspection tests on the simulated parts with rectangular groove artificial defects, the rationality of the ultrasonic simulation model and the validity of the calculation results were verified.Transverse wave sound field information of phased array probes with different frequencies was obtained through simulation analysis, and the probe frequency was optimized.According to the variation of echo amplitude of incomplete penetration with the focus depth under different welding penetration depths and the measurement results, the optimal value range of the focus depth was obtained.The simulation specimen of the generator head was used for testing and compared with the metallographic measurements.The results show that for the weld thickness of about 11 mm, the measurement error of penetration is less than 1 mm compared with the metallographic value, when using 10 MHz linear phased array probe and focal depth is 8 mm, which meets the quantitative requirements of engineering.
