6061 aluminum bar is widely used, so how should customers choose good quality materials when purchasing 6061 aluminum bar?Generally, our factory will test the 6061 aluminum bar after the production, and then issue the corresponding material report. Then the 6061 aluminum bar manufacturer will introduce to you the detection principle of 6061 aluminum bar.
Generally, the interior of 6061 aluminum bar is tested. Because the surface of 6061 aluminum bar is rough, the attenuation is relatively large.Generally, ultrasonic testing is used.
Detection principle: compressional pulse reflection in ultrasonic testing, the instrument (transducer) excitation probe ultrasonic flaw detection, ultrasonic pulse into the water, the water of the excitation of the first sound transmission medium and then spread to artifacts, 6061, when the ultrasonic wave across heterogeneous because of the difference of beam with the acoustic characteristics reflected (for example, when an air layer, layer, such as slag composite defects), according to its return to the original route, the diameter of the probe is described for the high frequency electrical pulse, to zoom in.According to different reflected waves, the existence, location, size and nature of defects are judged.
Detection sensitivity: a single defect detection sensitivity Φ 1.5 ~ 3 mm Φ in the required way to comply with relevant standards or bilateral agreement in the equivalent flat bottom hole;
The detection principle of 6061 aluminum bar is introduced here. If you need 6061 aluminum bar, please contact us.
