Bringing this up from the basement.
Had a second fail. How does a weld pass "tensile" and fail a bend?
NOW I know how. My "certificated" material is flawed.
I decided to do an entire "coupon-size" sample with all the materials I sent the failed coupons off with. I played with settings within the WPS I'm trying to prove. Ignore the nugget, because this was playing. Pay attention to the lines that appear in the half of the coupon that was cut from the "short" side of the very expensive sheet of traceable certified material.

Very interesting!
The manufacturer/distributor may want to see that. You never quite know where or in what the rest of that heat may end up.
Just as I was thinking "that looks like delamination..." I noticed the title of the pics.

Yep, I assume delamination failures will occur with any coupons cut from this end of the sheet. I had my TIG coupons pass, with material cut from much farter up the sheet, and that WPS is now qualified.
I'm going to have to cut another set of coupons from that end of the sheet, and I will polish and etch them before I spend any more hours prepping and welding them. I've wasted a good 15 hours on this faulty material already.
