Abstract
The invention relates to a soldering seam phased array ultrasonic transversal crack detecting method that sets 4 emitting and receiving ultrasonic probes on to one point of soldering seam. The probes on one side emit ultrasonic, and the other side receive ultrasonic, adjusting the distance between emitting probes and receiving probes to polymerizing point and the time, picking up the signal of transversal crack, and taking testing to each points. The invention still uses the existing phased array ultrasonic automatic testing system and realizes the detection for soldering seam transversal crack. And the result is accurate and reliable.
Description
Technical field
The present invention is the welding-seam phased array supersonic transverse crack detection method that detects with phased array supersonic automatic checkout system butt welded seam transversal crack.Relate to hyperacoustic field of measuring technique.
Background technology
Crackle is dangerous defects in the welding.Crackle in welding is broadly divided into five classes such as longitudinal crack, transversal crack, crater crack, arcuation crackle and sulfur crack.Still can find for bigger crackle radioscopy, but effect is not as good as ultrasound examination.And to crackle and micro-crack, Ultrasonic Detection then might omission as being unfamiliar with construction technology.Usually, the carbon content of steel is high more, and weldability is poor more, after being easy to generate crackle, particularly transversal crack more and occurring in high-strength steel pipeline girth joint, also is difficult to find with the phased array supersonic automatic checkout system.This problem is perplexing welding circle always, and serious hope can have the technology of solution.
Summary of the invention
The objective of the invention is to invent a kind of phased array supersonic automatic checkout system and detect accurate, the reliable welding-seam phased array supersonic transverse crack detection method of weld seam transversal crack.
At present detection with phased array supersonic automatic checkout system butt welded seam transversal crack exist insensitive, often the deficiency of omission arranged, the present invention is by the thorough head it off of following technical proposals.This method still detects with present general phased array supersonic automatic checkout system butt welded seam, but its method is: as shown in Figure 1, to become " ten " word layout 4 emissions, receive ultrasonic probe 1,2,3,4 with the weld seam be each 2 homopolymerization of the every symmetrically limit of axis of symmetry penetrate in weld seam a bit on, the probe emission ultrasound wave of one side, the probe of opposite side symmetry receives ultrasound wave, adjust emission, receiving transducer to the distance and the receiving transducer receive window time of reception that gather exit point, pick up the signal of weld seam transversal crack, and pointwise detects.Specifically be to be axis of symmetry two of each apportions of both sides symmetrically in one plane and with the weld seam by the 90 ° of installations in every interval with 4 ultrasonic probes 1,2,3,4, the transmit direction of every probe is poly-penetrate in weld seam a bit on, two probes with weld seam symmetry apportion weld seam both sides are one group, emission, the receive direction of every group of probe equate with the angle β of poly-exit point tangent plane, promptly pop one's head in 1,2 emissions, receive direction and angle β that should poly-exit point tangent plane equate, probe 3,4 emissions, receive direction and be somebody's turn to do the angle β that gathers the exit point tangent plane and also equate; Transmit direction and weld seam direction of welding 1, the 2 distance emissions of two survey upper surface transversal crack probes, the receiving position that are positioned at the weld seam both sides in the same way is respectively 6 times of welded part thickness, transmitting from probe begins to control the start time and the shut-in time of receive window, to receive the signal of upper surface transversal crack; Being transmitted into reverse two of weld seam both sides of being positioned at of the range transmission direction of reception and weld seam direction of welding surveys lower surface transversal cracks probe 3,4 and is respectively 5 times of welded part thickness apart from emission, receiving position, transmitting from probe begins to control the start time and the shut-in time of receive window, with the signal of weld seam lower surface transversal crack; So pointwise detects.Though 4 ultrasonic probes 1,2,3,4 here are mounted on the plane, hyperacoustic direction that transmits and receives is a directive weld seam obliquely not in this plane, and promptly transmitting and receiving direction and weld seam tangent plane has individual angle β (being incident angle).For measuring crackle, 1,2 the incident angle β of popping one's head at least should equate, the incident angle β of probe 3,4 should equate, incident angle β that also can 4 probes all equates certainly.In other words, 4 probe planes, place can with intersect in bead direction by poly-exit point tangent plane, also can be parallel.Simultaneously, the weld seam both sides are each 2 in 4 probes, and with the weld seam symmetric configuration, so the emission line of 4 probes is also all equating with the angle of weld seam by the projection on the poly-exit point tangent plane.Have only 4 probes in weld seam surrounding space layout like this, just can measure the transversal crack signal of weld seam.
Definite method of surveying upper surface transversal crack 1, the 2 window start times of probe deducts a constant 3.1 * 10 for the hyperacoustic shear wave of emission from the travel-time that is transmitted into reception
-6μ s, definite method of shut-in time adds a constant 3.1 * 10 for the hyperacoustic shear wave of emission from the travel-time that is transmitted into reception
-6μ s.These two times will calculate in advance as stated above, and concrete is calculated as: probe 1,2 is respectively 6 times of welded part thickness apart from emission, receiving position distance, and establishing T is welded part thickness, and the distance that is transmitted into reception so is: L=(2 * 6 * T)/COS β,
The start time of window: t
On={ (2 * 6 * T/COS β)/C
s}-(3.1 * 10
-6)
The shut-in time of window: t
Off={ (2 * 6 * T/COS β)/C
s}+(3.1 * 10
-6)
C wherein
sIt is the velocity of propagation of shear wave in the ultrasound wave.
Definite method of surveying lower surface transversal crack 3, the 4 window start times of probe deducts a constant 3.1 * 10 for the hyperacoustic shear wave of emission from the travel-time that is transmitted into reception
-6μ s, definite method of shut-in time adds a constant 3.1 * 10 for the hyperacoustic shear wave of emission from the travel-time that is transmitted into reception
-6μ s.Equally, these two times also will calculate in advance as stated above: probe 3,4 is 5 times of welded part thickness apart from emission, receiving position distance, and the distance that is transmitted into reception so is:
L＝(2×5×T)/COSβ
The start time of window: t
On={ (2 * 5 * T/COS β)/C
s}-(3.1 * 10
-6)
The shut-in time of window: t
Off={ (2 * 5 * T/COS β)/C
s}+(3.1 * 10
-6)
C wherein
sIt is the velocity of propagation of shear wave in the ultrasound wave.
And every group of emission, receive direction and this angle β of ordering tangent plane are controlled in the following scope: 0 °＜β＜90 °.Obviously, β does not have the refraction wave of crackle when 0 ° and 90 °, theoretically refraction wave should be arranged exactly near 0 ° and 90 ° the time, but in fact unsatisfactory, is preferably the stage casing between 0 °～90 °, promptly about 45 °.Pointwise as for weld seam detects, and distance should be little of being bordering on continuously between the check point when detecting, and so just omission can not occur.In fact, as long as 4 probes slowly move continuously, just can measure the crackle signal of weld seam continuously during detection.
Because this method is popped one's head in two groups 4 and emission, receive direction and the cross-seam of every group of probe, weld seam is if any transversal crack, ultrasound wave is mapped on the crackle will produce refraction because of the interface, again because of emission, receive direction and inject and order the angle of tangent plane and equate, so the ultrasound wave of refraction is received and reaction to some extent in detection system by another probe of this group, and then the having or not and size of transversal crack that can be true.
