CREATING THE ULTRASONIC MEASURING SYSTEM FOR THE DEFECT DIAGNOSTIC IN THE ALLOYING ZONE OF LAYERED METAL SAMPLES
The ultrasonic measuring system for the layered metal samples diagnostic has been created. Layers steel + steel and copper + steel have been investigated. The method of welding by the explosion was used in preparation of the layered structures. If a defect is present the total reflection is observed for all frequencies used. Consequently, the energy transmission coefficient is equal zero. The efficiency of the developed method for a layered system with bimetal layers is thereby demonstrated.
