The Intelligent Ultrasonic System for Quality Testing of Weld Connections in Turbine Runners

Article Preview

Abstract:

The intelligent ultrasonic testing system possessing capabilities of defect tracking and defect simulated analyzing has been developed in this paper according to the characteristic of defects existing in weld connections in turbine runners. The passage then introduces the testing system from angles of structure, function and operation, respectively. Finally, the testing system is applied to an in-service turbine runner and the results indicate that desired efficiency and accuracy of detection in the testing system can be achieved and the mean error of the length for defects can be held within 5mm.
