Water-immersion ultrasonic detection technology for titanium alloy structural component by direct laser deposition
The water-immersion ultrasonic detection of titanium alloy structural component by direct laser deposition was conducted using water-immersion ultrasonic C-scan testing system.The corresponding testing procedures were also estab-lished.The results showed that the testing procedure had the characteristics of high sensitivity and high signal-to-noise ratio.The proposed testing procedure was applied to the ultrasonic detection of some titanium alloy products by direct laser deposi-tion,and the results were compared with the radiographic testing and penetrant testing.The effectiveness of this testing pro-cedure was verified.
