Abstract
A reference block for detecting the incomplete penetration width of a T-shaped joint by a straight probe comprises a block body. At least five flat-bottomed grooves are arranged at the bottom of the block body, and the widths of the flat-bottomed grooves are different. The reference block can be manufactured according to wing plate materials and the thickness of the T-shaped joint, the reference block is made of steel materials as same as the wing plate materials, or the acoustic performance of the steel materials is similar to that of the wing plate materials, the flat-bottomed grooves can be manufactured in a machined mode by common machinery factories, and are simple in method and convenient to use. The reference block can serve as a reference block specified in an ultrasonic detection standard for detecting the incomplete penetration width of a T-shaped joint welding line, is used for adjusting and checking detection sensitivity when the straight probe is used for detecting the incomplete penetration width of the T-shaped joint welding line on a wing plate, solves the problem of difficulty in accurately measuring the incomplete penetration width of the T-shaped joint welding line, and provides data support for optimizing product design. Besides, construction difficulty is reduced, and the manufacturing cost of the reference block is saved.
Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of comparison and detection device that the lack of penetration width of T connector is used that detects.
Background technology
The detection of lack of penetration width is the difficult problem of puzzlement nondestructive testing personnel always in the T connector weld seam; During the lack of penetration detection of T connector weld seam for a long time; Adjustment and verification detection sensitivity all are to adopt hyphen hole, long cross-drilled hole and flat-bottom hole, and be bigger than normal to the error that detects lack of penetration width in the T connector weld seam like this.Designing requirement improves in designing unit, originally not the joint of through welding come requirement according to through welding, thereby increase difficulty of construction, strengthen the device fabrication cost.There is not the reference block of lack of penetration width in the suitable detection T connector weld seam that everybody generally acknowledges in the existing standard.
The utility model content
The purpose of the utility model provides the compare device of the lack of penetration width of T connector weld seam of the different flange plate thickness of a kind of accurate quantification.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises block, in the bottom of block at least five flat-bottom slots are set, and the width of each flat-bottom slot has nothing in common with each other.
The width of said five flat-bottom slots is followed successively by 1mm, 2mm, 3mm, 4mm and 5mm.
Adopt the utility model of technique scheme; Can make according to T connector wing plate material, thickness; The close steel of identical or acoustical behavior of the material of reference block and wing plate material, the utility model flat-bottom slot is with mach mode processing and fabricating, and common mechanical factory all can make; Method is simple, and is easy to use.The utility model can be used as in the lack of penetration ultrasound examination standard of T connector weld seam regulation and uses reference block; Adjustment and verification detection sensitivity when being used for that the T connector weld seam detected lack of penetration width at the wing plate place with normal probe; Solved the difficult problem that lack of penetration width is accurately measured in the T connector weld seam; For product design optimization provides the data support, reduce difficulty of construction, practice thrift the device fabrication cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2, the utility model comprises block 1, and at least five flat-bottom slots 2 are set in the bottom of block 1, and the width of each flat-bottom slot 2 has nothing in common with each other, and its width is followed successively by 1mm, 2mm, 3mm, 4mm and 5mm.
The detection principle of the utility model is: the material of block 1 adopts with the close steel of identical or acoustical behavior of wing plate material and makes; Length, the ultrasound wave when the width design avoids normal probe to detect disturb in the profile physical dimension, and Thickness Design is confirmed according to the wing plate thickness that detects T connector.Not soldering tip width design 1mm, 2mm, 3mm, 4mm and five flat-bottom slots of 5mm in the flat-bottom slot 2 simulation T connector weld seams are according to acoustic reflection characteristics in the steel, so that accurately measure in the T connector weld seam not soldering tip width.
The design of the utility model has taken into full account the characteristics that ultrasound wave is propagated in metal material; Avoid the characteristics of hyperacoustic interference, decay and acoustic pressure reflection; Through the utility model adjustment and verification detection sensitivity; Can accurately measure lack of penetration width in the T connector weld seam, guarantee the accuracy of testing result.In the detection, the WHT normal probe detects as shown in table 1 with the reference block size.
