Description
Technical field
The utility model relates to a kind of detection scanning coupling arrangement, specifically diffracted wave time difference method ultrasonic inspecting and scanning support.
Background technology
TOFD is the abbreviation of diffraction time difference technology (time of flight diffraction), is that a kind of diffracted wave propagation time difference of defective end that utilizes carries out defects detection and quantitative methods.This technology is proposed in late 1970s by Britain Harwell laboratory (UKAEA), is widely used in industrial circles such as nuclear power, building, petrochemical industry, rock gas at present.The TOFD technology is as a kind of newer ultrasonic detection technology, technology such as pulse reflection method different from the past and sound wave through transmission technique, and what its utilized is that the diffraction that the fastest compressional wave of the velocity of sound produces in the defective end in solid detects.In the weld seam both sides, the longitudinal wave oblique probe that a pair of frequency, size and angle is identical symmetry is in opposite directions placed, and one as transmitting probe, and another is as receiving transducer.The compressional wave incident detected weld section of transmitting probe emission.At the zero defect position, receiving transducer can receive lateral wave and the bottorm echo of propagating along the test specimen surface.And defectiveness is when existing, and between above-mentioned two ripples, receiving transducer can receive the diffracted wave of defective upper end and bottom.
Diffracted wave time difference method Ultrasonic Detection (TOFD) generally is made up of detector, scanning equipment and sensor.The effect of scanning equipment is that distance is maintained fixed, and probe is aimed at all the time, and provides probe positions information to detector, to produce the scan image relevant with the position.Probe positions information can be provided by scrambler.Scanning equipment is made automatic scanning by motor-driven, also available hand drive scanning.Can use suitable guiding mechanisms such as the autotracking unit of rail, steel band, tracing system and guide wheel.
Detect principle according to TOFD, scanning equipment must satisfy following function:
1, static probe keeps the distance between the probe, and keeps probe to aim at mutually, and the compressional wave of a pair of probe emission remains in the same plane, and this plane and scanning equipment direction of motion are maintained fixed angle.
2, detect workpiece for adapting to different-thickness, scanning equipment can conveniently be regulated the also distance between the measuring sonde.
3, scanning equipment can be installed many to probe.
4, scanning equipment must be adjacent to detected surface of the work, can stationkeeping when stop motion and do not break away from detected workpiece.
5, scanning equipment can keep certain direction of motion, and adjustment aspect can be in detection.
6, scanning equipment must can carry scrambler, provides probe positions information to detector.Scrambler and scanning equipment are synchronized with the movement, and need fit tightly detected surface of the work.
7, scanning equipment is striden weld seam detection (line of promptly popping one's head in is vertical with direction of motion) and suitable weld seam detection (line of promptly popping one's head in is parallel with direction of motion) except realizing probe.
Existing scanning equipment can not satisfy above-mentioned 7 contents simultaneously.In addition, the automatic scanning device is not suitable under the narrow space environment in the detection with the heavy wall weld seam owing to bulky.
