Ndt Application in Automotive Industry

(1) Ndt Application in Automotive Industry -Ultrasound Testing of Automobile Half-axle

Fracture failure of half axle is mainly due to high frequency and low-stress fatigue damage, and the existence of internal defects of workpiece is one of the important reasons for fatigue fracture. Ultrasound can be used to inspect the raw materials of the semi-axle and the semi-finished products after forging.

When diagnosing, the high-frequency electric pulse is transformed into ultrasonic wave by a probe, and the coupling agent enters the half axis. When the incident wave encounters defects (i.e. heterogeneous interfaces), due to its different acoustic properties, the reflected beam will be transformed into high-frequency electric pulse through the probe. After amplification, the position, size and nature of the internal defects in the half-axis can be judged according to the position, amplitude and waveform characteristics of the reflected echo.
