3.1

is the surface quality of the subject steel plate, size, shape automatic test equipment should meet the requirements.

3.2

in steel automatic ultrasonic testing personnel should be trained and familiar with the equipment performance, proficiency in computer and automatic ultrasonic testing system

And equipment, and obtain the relevant departments issued by the ultrasonic flaw detection level 1 and above professional qualification certificates. Reports issued by the relevant departments should get award

Hair ultrasonic flaw detection level 2 and above professional qualification certificates. Subject steel microstructure should not interfere in the examination of the impact test

Echo.

3.3

thick steel plate ultrasonic automatic detection is generally longitudinal wave.

3.4

Other requirements should be consistent with GB/T 2970 requirements.

Comparative Sample 4

Acoustic performance and materials 4.1 Comparative sample should be the same or similar subject steel plate, and shall ensure that its internal inspection does not affect the existence of the defect.

4.2

probe performance test specimens used for comparison should be consistent with GB/T 2970 requirements.

4.3

Dynamic test panel should be processed a certain number and type of artificial defects, including at least check the surrounding surface and a flat bottom hole or blind spot detection

Groove, and an artificial defect sensitivity calibration required. Dynamic test plate dimensions shall comply with the requirements of automatic testing equipment. Dynamic test plate can participate
