HAZ impact test specimen removal question per Div. 1
(OP)
I am qualifying a test plate that has a variable double-V groove that has a groove depth of 1 inch on one side and 6 inches on the opposite side. Per Fig. UG-84.5 and Table UG-84.6, two set of HAZ impact specimens shall be removed from a depth of between (1/4)t to (1/2)t from each weld surface. Does this mean that one set shall be taken from (1/4)t to 1/2(t) from the 1 inch groove depth and the same distance from the 6 inch groove depth (i.e. 1/4 to 1/2 inch from 1 inch groove depth and 1.5 inch to 3 inch from 6 inch groove depth) or (1/4)t to (1/2)t from full 7 inches (i.e. 1.75 to 3.5 inch)?
