Dear Experts
ABS Guide for NDE on Hull Welds-2002-Section 3.11.2- "Basic Calibration Block- Material whick the block fabricated is to be of the same product form, heat treatment, material specification and accoustically similar material being examined".
I'm working with Materials like - AH36/DH36/EH/36.EQ51/EQ57 -Series.
Does separate individual calibration/reference block required or block made of ASTM A36 is enough?
This is my understanding of what is staed in ABS Guide:-
1- Product Form - Manufacturing process - Rolling/Forging/Casting..etc
2- Heat treatment- annealing/normalized..etc
3- Mat Specification - Carbon Steel/StainlessSteel /Duplex Stainless Steel Steel/CuNi- need block form same/equivalent material.
AWS D1.1- calls for ASTM A36 or acoustically equivalent material is enough.
Pls explain as detail as possible.
Thanks in advance.
