OK, I believe I have over thought this and now confused myself, which is not hard to do. I know I can count on the superior brian power here to help.
D17.1 par. 4.3.3.1 (1) states "A test weld with a base metal thickness of t shall qualify welds with a thickness range of 0.67 t to 4t, except that when the test weld thickness is equal to or greater than 1", the qualification range is 0.67t to unlimited. Two test welds shall qualify welds with all intermediate thicknesses".
Therefore I can perform two test welds, a 1" and a 0.125" test weld thickness, to qualify .06" to unlimited. Did this come out right?
