Description
Technical field
The present invention relates to ultrasonic examination technical field, in particular to the ultrasonic wave of a kind of big pipe angle seam of high-pressure bottle
Detection method.
Background technique
Petrochemical industry be unable to do without pressure vessel, and safety is directly related to the safety of life and property of people again.
The structure of many corner joints is more complicated in pressure vessel, force-bearing situation is poor, and detection difficulty is big, and omission factor is high, characterization processes
It is complicated.National " boiler and safety-supervision regulation of pressure vessel " just has a regulation in one's early years, and equipment is mainly not allow in compression weld seam
Fillet weld.With the development of science and technology and new diseases, occur bearing the fillet welding of pressure in many equipment in recent years
Seam.This just to fillet weld detects and puts forward new requirements, but flaw detection of the engineers and technicians of industry many to fillet weld
Technology is also not very clear.Due to the particularity of fillet weld position, general detection method be easy to cause the missing inspection and mistake of defect
Sentence, therefore select a kind of good method of detection, is the key that guarantee fillet weld detection quality.
With being constantly progressive for science and technology, many compression fillet welding of flat-shaped end socket are used in pressure vessel more and more
Seam.Compared with conventional butt weld, the geometry of fillet weld, which is more complex than, to be produced not only including T-type fillet weld, but also including L
Whether type fillet weld, general fillet weld are cracked using ultrasonic listening.
Traditional ultrasonic listening mode generally uses two kinds, a kind of that normal probe is selected to carry out ecto-entad against weld seam
Ultrasonic listening, a kind of sound wave reflecting properties that selecting angle probe are vertically attached in detection faces, from inside to outside by back wave
Ultrasonic listening, the two cannot combine well, and Effect on Detecting is caused to be deteriorated, if general selection angle probe, every kind of spy
Shear refraction angle is of different sizes in the detected workpiece of the sound wave of head, therefore is difficult to choose suitable probe, and shear wave is selected to roll over
It is easy to generate scan blind spot, and the position due to not knowing defect if the size of firing angle is improper, it is therefore desirable to not stop
Mobile probe detection piece is scanned, can not first determine a mobile face on a large scale in this way, cause to detect work quantitative change
Greatly, detection efficient is reduced.
Summary of the invention
The object of the invention is that in order to be easy to appear detection blind area when solving above-mentioned ultrasonic listening Welding Crack,
Probe be inconvenient to select, the low problem of detection efficient and a kind of big fillet ultrasonic test side of high-pressure bottle is provided
The advantages of method, there are two types of probe detection results for tool more accurately, comprehensively, and pre-detection determines range, improves detection efficient.
The present invention is achieved through the following technical solutions above-mentioned purpose, a kind of ultrasonic wave of the big pipe angle seam of high-pressure bottle
Detection method, comprising the following steps:
The preparation of S1, detection faces: the greasy dirt on examined part surface is washed away, and the oxide on examined part surface is polished flat
It is sliding；
The pre- scanning of S2, detection faces: carrying out scanning to test specimen to be detected with magnetic memory detector, by magnetic memory signal mutation
Position is recorded；
The selection of S3, ultrasonic listening equipment: selecting suitable ultrasonic wave detector and couplant, and ultrasonic probe uses
Normal probe and angle probe are used cooperatively, and the frequency of two kinds of probes is between 2.5-5MHZ, and the K value of angle probe is (for indicating tested
Survey the size of shear refraction angle in workpiece) it is selected between 5-25 °, and at least the angle probe of two different K values is selected to be detected；
Couplant: being applied to the surfaces of two kinds of probes by S4, ultrasonic scanning, opposite between the sound wave emitting head of normal probe
Weld seam, the surface of angle probe perpendicular contact pipeline, Level tune angle probe is moved in pipe surface under the cooperation of CSK-IA test block
Dynamic, one position of every movement records the incidence point and K value of angle probe in the position, carries out emphasis in the point of step S2 record and sweeps
It looks into；
S5, defectoscopy, record and ranking: in detection process, when defect highest wave is more than quantitative line, according to survey
The data obtained judge defective locations, if defect is located on weld seam, then quantify to it, the depth of defect is directly displayed at inspection
It surveys on the screen of instrument, length needs hand dipping, records defect according to the regulation of JB/T 4730.3-2005, each to record to lack
Sunken parameter carries out grade classification, and makes ranking table.
Preferably, the step S1 carries out the greasy dirt on detected member surface by using acetone or absolute alcohol clear
It washes, oxide polishing is wiped repeatedly using dry sanding paper.
Preferably, the ultrasonic listening equipment of the step S3 is model: the ultrasonic detector of IDEA-UT2008, coupling
Mixture is water, machine oil or chemical paste.
Preferably, ultrasonic wave used in the normal probe and angle probe of the step S3 is shear wave.
Preferably, along bead direction circular scanning, angle probe is vertically done with bead direction the normal probe of the step S4
Saw-tooth sweep.
Compared with prior art, the beneficial effects of the present invention are:
By using magnetic memory detector to carry out prescan, and tracer signal to detection piece before ultrasonic scanning defect
The position of mutation reuses ultrasonic wave detector in this way and carries out emphasis detection to mutated site, can reduce defects detection
Range can go out defective locations in this way with rapid survey, reduce workload, so that detection is more preferably efficient.
Ultrasonic wave detector is in such a way that normal probe and angle probe are used cooperatively, so that Defect Scanning is more comprehensive, and
And the probe that angle probe selects at least two K values (for indicating to be detected the size of shear refraction angle in workpiece) different, therefore
Can guarantee to be not in scan blind spot when mobile angle probe, guarantee that detection result is more accurate.
The parameters of the position of each defect, ultrasonic wave are recorded by defectoscopy, record and ranking,
And according to normal parameter as standard, ranking is carried out to defect.
