Abstract
The utility model provides an ultrasonic flaw detection steel sample bar welding structure which comprises a first bar and a second bar, wherein the periphery of the ends of the first bar and the second bar is provided with an arc welding groove; the first bar and the second bar are welded into a whole through the welding groove; the end of the first bar is provided with an artificial cross hole; a 90-degree right angle is formed between the connecting end face of the first bar and the second bar and the bars; the surfaces are planes subjected to mirror surface treatment; the accurate grinding roughness of the plane is less than 0.34mu m; and the arc welding groove is an arc peripheral surface with the width of 5-10mm and the depth of 2-5mm. Compared with the prior art, the ultrasonic flaw detection steel sample bar welding structure has the advantages that the equivalent defects of larger than 0.3mm such as entrainment, slag inclusion, air holes and cracks are avoided at the sample bar connecting part, the requirement of the bars on the straightness can be guaranteed, and the ultrasonic flaw detection steel sample bar welding structure is simple in structure and high in checking accuracy.
Description
Technical field
The utility model relates to a kind of detecting instrument accessory, relates in particular to a kind of ultrasonic inspection steel lining bar welded structure that detects order of accuarcy for the checksum test reflectoscope.
Background technology
Ultrasonic inspection steel lining bar, refer to the rod iron that rod iron inside comprises " artificial cross-drilled hole ", be mainly used in the accuracy of detection of ultrasonic inspection equipment is carried out to checksum test, this lining bar do not allow artificial cross-drilled hole periphery to exist to be greater than the 0.3mm equivalent such as being mingled with, slag inclusion, pore, defects i.e.cracks exist, these defects will produce the acoustic effect to artificial cross-drilled hole, it is noise effect, and after will guaranteeing to process, good flatness and strength of joint are arranged, flatness control is at every meter below 1 ‰, strength of joint can allow to use overhead traveling crane to carry out handling
At present, this type of ultrasonic inspection steel lining bar is artificial cross-drilled hole and processes later syndeton, roughly be divided into two kinds: the first (referring to shown in Fig. 1) is the miter angle screw connection structure, this kind of structure is very high to requirement on machining accuracy, and can not guarantee that connecting portion does not exist the influential acoustic effect of ultrasonic inspection, i.e. noise effect after connecting; The second (referring to shown in Fig. 2) is taper jam welding connecting structure, uses technique for overlaying that the pyramidal structure repair welding is coupled together.This kind of syndeton can not guarantee that vertebra welded corner joint position affects without ultrasonic noise, and welding stress easily causes the steel lining bar to produce bending.These two kinds of lining bar structures all can not well meet the quality requirements of ultrasonic inspection equipment to lining bar, thereby lose calibration and the test function of lining bar to the defect-detecting equipment precision.
Given this, be necessary to provide a kind of new ultrasonic inspection steel lining bar welded structure to solve above-mentioned technical matters.
Summary of the invention
The technical matters that the utility model solves is to provide a kind of simple in structure, verification ultrasonic inspection steel lining bar welded structure accurately.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of ultrasonic inspection steel lining bar welded structure, comprise the first bar and the second bar, described the first bar and the second bar end periphery are provided with the arc bevel for welding, described the first bar and the second bar are welded as a whole by bevel for welding, and described the first bar end is provided with artificial cross-drilled hole.
As the further improvement of the technical program, described the first bar and the second bar connecting end surface and bar are 90 degree right angles, are the plane of carrying out mirror process, and the planar accurate grinding roughness is less than 0.34 μ m.
As the further improvement of the technical program, the arc side face that described arc bevel for welding is wide 5-10mm, dark 2-5mm.
As the further improvement of the technical program, the inner metal powder of filling of described artificial cross-drilled hole.
Compared with prior art, the utility model reflectoscope steel lining bar welded structure can guarantee that the lining bar connecting portion exists without being greater than being mingled with of 0.3mm equivalent, slag inclusion, pore, defects i.e.cracks, and can guarantee the requirement of lining bar to flatness, it is simple in structure, and the verification accuracy is high.

[embodiment]
Refer to shown in Fig. 3, the utility model provides a kind of ultrasonic inspection steel lining bar welded structure, it comprises the first bar 1 and the second bar 2, described the first bar and the second bar end periphery are provided with arc bevel for welding 3, described the first bar and the second bar are welded as a whole by bevel for welding, described the first bar end is provided with artificial cross-drilled hole 4, the inner metal powder 5 of filling of described artificial cross-drilled hole 4.
The arc bevel for welding 3 of described the first bar 1 and the second bar 2 is processed, drill artificial cross-drilled hole on the first bar 1, fill metal powder 5 shutoff, then the connecting end surface of the first bar 1 and the second bar 2 is carried out to mirror process, the planar accurate grinding roughness is less than 0.34 μ m.Then by the first bar 1 and the second bar 2 joint faces docking, two ends apply the prestress that is not less than 3Mpa, keep bar at the temperature of 200-300 degree, and to arc bevel for welding 3 use, the welding rod close with the Steel Bar During material carries out built-up welding and be connected.
The utility model reflectoscope steel lining bar welded structure can guarantee that the lining bar connecting portion exists being mingled with of 0.3mm equivalent, slag inclusion, pore, defects i.e.cracks without being greater than, and can guarantee the requirement of lining bar to flatness, and it is simple in structure, and the verification accuracy is high.
The above; it is only most preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any those of ordinary skill in the art; do not breaking away from technical solutions of the utility model scope situation; utilize the method content of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, all belong to the scope of claims protection.
