Description
Technical field
It the utility model is related to ultrasonic examination technical field, more particularly to a kind of ultrasound examination dress of lack of penetration weld seam
Put.
Background technology
Ultrasonic examination is to penetrate the depths of metal material using ultrasound, and when entering another section by a section,
The characteristics of interface edge reflects checks a kind of method of part defect, when ultrasonic beam is passed to from piece surface by popping one's head in
Metal inside, defect is run into back wave just occurs respectively during part bottom surface, impulse waveform is formed on fluorescent screen, according to these
Impulse waveform judges defective locations and size.There are a variety of wave modes when ultrasonic wave is propagated in media as well, it is the most frequently used in inspection to be
Compressional wave, shear wave, surface wave and Lamb wave.With the detectable cast metals of compressional wave, blank, cut deal, large forgings and shape matching letter
The defects of field trash, crack, the draw, white point in the presence of single product, layering；With the circumference in the detectable tubing of shear wave and
Axial crack, scuffing, gas pore in weld metal, slag inclusion, crack, it is lack of penetration the defects of；With the casting of the detectable simple shape of surface wave
Surface defect on part；With the defects of detectable thin plate of Lamb wave.
Ultrasonic creeping wave is the compression compressional wave that refraction angle is 90 °, and maximal amplitude direction and surface are into a low-angle, only on surface
Lower propagation, surface scattering is relatively weak, insensitive to surface roughness, is particularly suitable for detecting Coarse Austenite material surface, near
The crackle of the inspection of defect, such as casting, overlay cladding sub-surface defect crackle and bolt root in surface defect and thin pieces
Deng.
During ultrasound examination, the transmitting and reception of ultrasonic wave are picked up by popping one's head in realize.The performance of probe is straight
Connecing influences the characteristic of ultrasonic wave, influences the detection performance of ultrasonic wave.The probe used in ultrasound detection, it is the pressure using material
Electrical effect realizes electric energy, the transducer of acoustic energy conversion.Critical component in probe is chip, and chip, which is one, has piezo-electric effect
Monocrystalline or polycrystal thin slice, its effect is to change electric energy and acoustic energy mutually.
Angle welding is widely used in the departments such as electric power petrochemical industry on the hardwares such as each middle container conduit, its matter
Amount situation directly influences the safe operation of equipment.Angle welding is different from butt weld to the connected mode of structural elements, and it is welded
Mutually having a certain degree for the structure of both sides is stitched, from the point of view of terms of mechanics, stress concentration is easily caused, causes crack initiation,
And crack orientation is existing parallel also has vertical weld direction.
Lack of penetration finger base metals are unfused, and weld metal does not enter into the phenomenon of the root of joint.Pipeline typically uses method
Orchid connection, flange are connected with preferable intensity and compactness, and applicable size range is wide, can be applied in equipment and pipeline,
So using most universal.Flange is divided into integral (type) flange, loose type flange, any formula flange.Lack of penetration welded flange belongs to any formula
Allow lack of penetration flange occur in flange, industrial pipeline and high-tension electricity equipment.In actual mechanical process, often occur not melting
Close, equipment in the process of running, due to reasons such as stress and vibrations, easily cracks lack of penetration angle welding in addition.Cause
This needs regularly to carry out nondestructive evaluation to the equipment, excludes hidden danger in time.
