PURPOSE: To provide a device capable of closely adhering a probe onto a welded surface even when the welded surface is inclined, and improve the working efficiency of ultrasonic flaw detection. CONSTITUTION: This device has a pair of motors 1; axial feeding screws 3 connected to the motors 1, respectively, to rotate; arms 5 screwed to the screws 3, respectively, to vertically move; slide arms 7 connected to the arms 5 through springs 6; rod ends 8 provided on the lower ends of the slide arms 7; and an end shaft 9 connected to the respective rod ends 8. A probe 10 is provided on the end shaft 9, whereby the probe 10 can be closely adhered to a welded surface even when the welded surface is inclined, and a precise ultrasonic flaw detection result can be provided. Further, the working efficiency can be also improved by devising the ultrasonic flaw detection. |
