Description
Technical field
The invention belongs to weld seam detection technical field, is related to a kind of girth joint ray detecting apparatus and method, more particularly to
A kind of caliber is in the radiography detection means and method more than 89mm girth joints.
Background technology
Ring banjo fixing butt jointing weld seam（Abbreviation girth joint）It is weld seam form common in pipeline, container, its internal soundness master
Radiography is relied on to detect to evaluate.Radiography detection is one of method of five big conventional Non-Destructive Testings, in detection boxing
It is very ripe using existing history for many years in seam, 89mm girth joint is more than for diameter, in order to consider the detection of transversal crack
Ability and annular banjo fixing butt jointing midfeather thickness on beam direction, both sides wall thickness is big the problems such as, according to GB3323-2005
《Metal molten welds welding point radiography》、JB4730.2-2005《Bearing device Non-Destructive Testing part 2：Ray detection》
Deng regulation, completed using segmentation, the detection of multiple transillumination, such as caliber 100mm, wall thickness 3mm girth joint do ray detection, it is necessary to
Detection number be：In the case of conventional focal length 600mm, look into JB4730.2-2005 and scheme D.3<Source is in outer single wall transillumination ring
To butt welded joint, transmiting time figure of the transillumination than K=1.1>, minimum transmiting time is obtained as 9 times, i.e., by this φ 100 weldering
Seam is along the circumferential direction divided into 9 sections, and 1 transillumination length is 35mm, and 9 times transillumination completes detection, and this is according to general detection sensitivity
Requirement transillumination situation, if under high sensitivity technical requirements, detection number it is more, shooting 1 need to be segmented, paste font
3 minutes, 3 minutes transillumination time, the 30 minutes time of developing a film, 60 ~ 240 minutes drying times etc., a total of about 1.5 hours or so, institute
So that existing girth joint ray detection method for detecting efficiency is low, and testing cost is higher.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of detection efficiency for avoiding girth joint segmentation from detecting is low, inspection
The high girth joint ray detecting apparatus of cost and method are surveyed, improves detection efficiency.
In order to solve the above technical problems, the present invention provides following technical scheme：
A kind of girth joint ray detecting apparatus, including radiographic source（1）, block stereotype（2）, girth joint（3）, film（4）, screen
Cover stereotype（5）, transmission mechanism, it is characterised in that the radiographic source（1）It is arranged on and blocks stereotype（2）Surface, it is described to block lead
Plate（2）It is arranged on girth joint（3）Top, block stereotype（2）Centre opens up slot（w）, the hole（w）Vertical centerline
Through girth joint（3）The center of circle, film（4）It is arranged on girth joint（3）Inwall on, as transillumination, shield stereotype（5）It is arranged on
Film（4）Inner side, transmission mechanism are connected with being welded with the pipe fitting of girth joint, drive film, the shielding of girth joint and circumferential weld internal
Stereotype is rotated.
Further, the shielding stereotype（5）It is the cylindrical shape coaxial with girth joint.
Further, the hole（w）Width is 3-8mm, length is determined with girth joint width and heat affected area width.
A kind of girth joint ray detection method, it is characterised in that step is as follows：
A. stereotype is being blocked（2）On open up slot（w）, block the radiographic source on stereotype top（1）Through the hole（w）
Form transillumination area；
B. by film（4）It is attached to girth joint（3）Inner side；
C. in film（4）Inner side fixed mask stereotype（5）, make transillumination girth joint（3）Ray can not enter down during upside
On side weld；
D. pipe fitting and girth joint are driven by transmission mechanism（3）Rotate, 1-3 is rotated in the time of 3-5 minutes in transillumination
Circle；
E. film is taken out after the completion of transillumination, completes ray detection.
Further, the hole（w）Width is 3-8mm, length is determined with girth joint width and heat affected area width.
The beneficial effects of the present invention are：
The present invention compared with prior art, solves girth joint segmentation transillumination, transmiting time is more, detection efficiency is low, detection
The problems such as cost is high, detection efficiency can be effectively improved, reduce detection scheme, and scheme is implemented simply, easily.
Brief description of the drawings
Fig. 1 is ray detection scheme schematic diagram.
In figure：1st, radiographic source, 2, block stereotype, 3, girth joint, 4, film, 5, shielding stereotype.
Embodiment
