Titanium and titanium alloy sheets ultrasonic detection method
1 Scope
This standard specifies the method for ultrasonic inspection of titanium and titanium alloy sheet. Including the principle of the method, general requirements, testing equipment, contrast
Select the test block detection mode, the detection, evaluation and inspection records and reports.
This standard applies to Lamb wave method using a thickness of 0.3mm ~ 6mm titanium and titanium alloy sheet of ultrasonic testing.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein
Member. For undated references, the latest edition (including any amendments) applies to this document.
JB/T 10061 A-mode pulse reflection type ultrasonic detector General technical conditions
3 PRINCIPLE OF THE METHOD
Lamb waves in the structure having two parallel surfaces of one by the shear and compression coupling from each other, and spread over the entire thickness
Stress wave. Mainly used to detect titanium and titanium alloy sheet internal stratification, cracks and other defects, and other exposed or not exposed to the surface of the tissue
Discontinuities.
4 General requirements
4.1 Operating personnel engaged in titanium and titanium alloy thin ultrasonic inspection should meet ministerial or equivalent level Ⅰ learn and above NDT
Measuring the level of qualification, the issue of inspection reports and explanations should reach the ministerial or equivalent level and above grade Ⅱ learn NDT personnel
Qualification levels.
4.2 ultrasonic examination should be carried out in titanium and titanium alloy sheet finished state. By all round the subject sheet metal shear surface should be neat uniform, flat surface,
There should be no case affect the test results of oil droplets, pits, corrosion.
5 Testing Equipment
5.1 Detector
Lamb wave testing instruments used should have a sufficiently high transmit power and a wide transmit pulse width. For the A-mode pulse reflection
Ultrasonic detector should meet the JB/T 10061 requirements.
5.2 Probe
5.2.1 fixed angle or variable angle probe probe, wafer size 20mm × 30mm or 30mm × 40mm, the wafer may be used
Area not less than 600mm2 other Lamb wave probe. Probe frequency should be within the range of 1.25MHz ~ 5MHz, frequency and its standard
He said frequency shall not exceed the difference between the nominal frequency ± 10%.
5.2.2 The probe should be smaller frontier blind, blind test plate end face is generally not more than 50mm.
