Research about Automatic Ultrasonic Testing Technology for the Ring Welding Line of Middling and Small Modulus Gear

Abstract

In order to resolve the problem of being unable to test the ring welding line of middling and small modulus gear by handwork ultrasonic testing due to small size, the automatic ultrasonic testing technology is studied and the automatic ultrasonic testing system has be studied. Normal beam testing adopts the radial incident detection methods from the inside hole surface using a higher frequency focus probe and the better testing result is obtained. The automatic ultrasonic testing system is made up of ultrasonic testing subsystem, mechanism scan subsystem, control subsystem, ultrasonic testing signal processing and display subsystem, and system calibration test pieces .The result of testing can be displayed on the computer screen or printed in the form of curve and statistical data.
