[Hindi] How to draw DAC in Ultrasonic Testing (UT)

DAC - Distance Amplitude Curve is a basic step in Ultrasonic Testing (UT) calibration before scanning the job piece. In this video, everything explained practically step by step for easy understanding.

[@sanjeevarao4071]

Please Make a video with 19mm block as well..

[@giraja_shankar]

Sir very easily you have explained to draw DAC!
VERY GOOD EXPLANATION!
THANK YOU

[@Alexander-uq7lm]

07:21 .sir, the FSH u have taken is 70% only, it needs to be 80% right ??

[@WeldingandNDT]

80% FSH is to be set while fixing the fist echo of DAC only, not everywhere. This video is an extract. Please watch my UT video series for complete explanation. Link: th-cam.com/play/PLZyz5C7MAALyZP0tX_F5dMxV4bwN1TE5q.html

Sir,
When to use 19 mm , 38 mm & 76 mm block.
Also, is my dac of 19 mm block valid for thickness like 30 mm material?
Pls clear my confusion.

[@abhishekprakash4291]

Material thickness
Upto 25mm thickness = 19 mm DAC block
>25 mm to 50mm = 38 mm DAC block
>50 mm to 100mm= 76 mm DAC block
