Ultrasonic flaw detector
Product introduction
Ultrasonic flaw detector is a portable industry non-destructive
inspection instrument, which can carry out testing, location and
evaluation of the multi-defects (such as crack, shrinkage, pore
slag, and so on) quickly, conveniently, scathelessly and accurately
and then prevent and avoid to arise safety accidents. It is mainly
used to the boilers, pressure vessels, avigation, war industry,
shipbuilding, automobile, machine building, metallurgy, metal
processing, steel structure, railway communication, nuclear energy
celebration and laboratory of the high school and so on.
Inspection theory
Ultrasonic flaw detector is the instrument that employ ultrasonic
testing method to test the material. The theory is that the change
of the acoustic property and internal structure of the material
have effect on the ultrasound propagation, when the ultrasound
propagate through the material. Ultrasonic testing is the
technology that know the change of material property and structure
by testing the acoustic and status. Generally, ultrasonic testing
method has many methods, such as transmission method, pulse
reflection method and tandem method, and so on.
