Sorry guys for all the confusion. I guess I stated the question wrong.
Per D1.1, 4.11.2 and figure 4.19, if I want to qualify for single pass fillet welds only, lets say 1/4 inch, do I still need to go through the whole process of putting a multi pass weld on the test peice or is it neccessary?
Also:
I know if max material thickness used in construction is less than the required test peice material thickness then you can use it for the test.
Then will this thickness become the maximum material thickness qualified?
Thanks alot,
