How is the distance-amplitude curve created during ultrasound testing?

So, should it be set to 80 for 40mm workpieces? And should it be set to 160 for 80mm workpieces? For workpieces over 50 mm whose thickness needs to be doubled, should an 80 mm curve be used and a CSK-IIA-3 test block employed? The standard specifies that CSK-IIA-2 is sufficient to cover thicknesses ranging from 40 to 100 mm.
Yes, according to 47013.3, for weld defects, it is necessary to perform scanning and observe both the first wave and the second wave (twice the sound path length).
