Abstract
A kind of adjusting test block of composite weld ultrasonic wave DAC curve plotting, including mobile face stainless steel layer and the carbon steel layer of popping one's head in, the mobile face stainless steel layer of popping one's head in is fixed on the upper end of carbon steel layer, is located at lower end surface 10mm, 20mm, 30mm and 35mm vertically away from mobile face stainless steel layer of popping one's head in the carbon steel layer and is equipped with the horizontal through-hole that diameter is 3mm.The test block can help inspector to adjust reasonable DAC curve in the compound seam inspection of stainless steel, formulate and rationally evaluate line, quantitative line, sentence scrap wire, while can also be used as the debugging test block of ultrasonoscope probe K value and Front distance.
Description
Technical field
The utility model relates to a kind of adjusting test blocks of composite weld ultrasonic wave DAC curve plotting.
Background technique
The welding of stainless compound steel plate causes supersonic detector to make DAC curve in traditional RB series standard test block
Afterwards, when leading to ultrasound examination because of composite variation, not only Main beam is reflected, and sound can also have certain decaying, causes to examine
Survey person cannot produce correct DAC curve on ultrasonoscope, be easy to cause in detection and judge by accident.
Utility model content
Its purpose of the utility model, which is that, provides a kind of adjusting test block of composite weld ultrasonic wave DAC curve plotting, solution
Determined clad steel plate seam inspection when composite aspect ultrasonic examination when, DAC curve plotting is difficult and determining defects inaccuracy
The problem of, which can help inspector to adjust reasonable DAC curve in the compound seam inspection of stainless steel, and it is reasonable to formulate
Evaluation line quantitative line, sentences scrap wire, while can also be used as the debugging test block of ultrasonoscope probe K value and Front distance.
It adopts the technical scheme that achieve the above object, a kind of adjusting of composite weld ultrasonic wave DAC curve plotting
Test block, including pop one's head in mobile face stainless steel layer and carbon steel layer, the mobile face stainless steel layer of popping one's head in are fixed on the upper end of carbon steel layer,
It is located in the carbon steel layer at lower end surface 10mm, 20mm, 30mm and 35mm vertically away from mobile face stainless steel layer of popping one's head in
The horizontal through-hole for being 3mm equipped with diameter.
Beneficial effect
The utility model has the following advantages that compared with prior art.
The utility model has the advantages that inspector can be helped more accurately to make when detecting stainless steel composite weld
DAC curve correctly determines Defect Equivalent, assessment grade, at the same can also be used as ultrasonoscope probe K value and forward position away from
From debugging test block.
Detailed description of the invention
Below in conjunction with attached drawing, the utility model is described in further detail.
Fig. 1 is the side structure cross-sectional view of the utility model；
Fig. 2 is the overlooking structure diagram of the utility model.
Specific embodiment
A kind of adjusting test block of composite weld ultrasonic wave DAC curve plotting, including pop one's head in mobile face stainless steel layer 1 and carbon steel

Diameter Wei Yu not be equipped with as 3mm at lower end surface 10mm, 20mm, 30mm and 35mm vertically away from mobile face stainless steel layer 1 of popping one's head in
Horizontal through-hole 3.
Horizontal through-hole 3 at described 10mm, 35mm is located in same vertical line, the horizontal through-hole at described 20mm, 30mm 3
In in same vertical line.
The mobile face stainless steel layer 1 of the probe is made of stainless steel material.
The carbon steel layer 2 is made of carbon steel material.
Embodiment
A kind of adjusting test block of composite weld ultrasonic wave DAC curve plotting, the test block specification be 300mm long, 43mm high,
30mm wide, including pop one's head in mobile face stainless steel layer 1 and carbon steel layer 2, as shown in Figure 1 and Figure 2, the mobile face stainless steel layer 1 of the probe
It is fixed on the upper end of carbon steel layer 2, the lower end surface vertically away from mobile face stainless steel layer 1 of popping one's head in is located in the carbon steel layer 2
The horizontal through-hole 3 that diameter is 3mm is equipped at 10mm, 20mm, 30mm and 35mm.
The utility model corrects ultrasonic wave at stainless steel and the different interface of carbon steel by using stainless steel and carbon steel composite
The angle that acoustic beam deflects when propagation measures more accurate horizontal through-hole waveform equivalent, it is ensured that the reasonable production of DAC curve helps
Inspector determines defect rank using correct DAC curve.
