You have great points, I appreciate. The weld size thing tho. This is aluminum, TIG welded with a Lincoln transformer. The size requirement as per D17, I believe is, .060-.120 throat and leg. This weld is we’ll under .120

I’ve submitted hundred of specimen to NDT and always have porosity or IF or both. Other people I work with have done hundreds and hundreds before passing...
