Description
Overview
GAOTek Flaw Detector with 100 Independent Setup (3 Staff Gauge) is a portable industrial non-destructive flaw detector, which can rapidly inspect, evaluate and diagnose various defects (crack, inclusion and pinhole, etc.) in a work piece without destruction. This instrument can be widely used in any fields that need defect inspection and quality controlling e.g. manufacturing industry, metallurgical industry, metal working, chemical industry, etc., also be broadly used in the active safety inspection and service-life evaluation in such fields as aerospace, railway transportation and boiler pressure vessels, etc. It is an essential instrument for non-destructive inspection industry.
When the ultrasonic wave propagates in a job, one can detect the defect in it by the influence on the propagation of ultrasonic wave based on the acoustic characteristic demonstrated by the defect in the material. Based on this principle, by using ultrasonic wave one can measure such defects as crack, pinhole and inclusion in such media as metal, non-metal and composite, etc.
