TCG Curve

What Is Ultrasonic Testing DAC/TCG Curve? What Is Ultrasonic Testing DAC/TCG Curve? DAC Curve Concept: DAC=Distance Amplitude Curve The DAC curve, or “Distance-Amplitude Curve”, represents the relationship between the amplitude of echo signals and the distance of the ultrasonic waves. For defects of the same size, the echo amplitude varies due to different sound path … Read more
