Features shadow control method

Development of a technique defectoscope (Descrydefect) or designing the system for automatic control begins with the selection scheme of control: control method, such as waves, surface through which sound waves are introduced, the input angle. To control the metal is mainly used in the echo, shadow and mirror-shadow methods.

Shadow method control thin, layered (eg, soldered) metal surface with a simple form. As a rule, it requires access to the two surfaces of the product. Mirror-shadow method is used when accessing the one surface when the faults do not provide an echo (e.g., because of a dead zone or due to unfavorable orientation of the defect), but attenuate the signal.
