Inquisition about New Ultrasonic Testing Method for High Temperature Alloy Bars with Small Diameter

  • In this paper,Ultrasonic testing methods are discusseed for high temperature alloy bars with diameter smaller that 16mm,The testing results are compared which indicate that the axial line focussed double probe testing method is more effective for small bars.
