摘要: A supersonic or ultrasonic wave flaw detector in which acoustic boundaries of flaws and/or abnormality materials within an object to be inspected is detected by waves and the position shape such a are displayed. hard sector-scanned with beam variable-angle probe direct contact object. In range comparatively small incident angles at longitudinal mainly penetrates object, sectional images due echo signals displayed on display screen scanning lines representative transmission speed direction wave. large where shear other hand, For this, sweeping for switched accordance ranges angles. The detecting operation modes thus combined covers complete image screen.
