6G Sch 80 3 in pipe with backing ring, with 11018

I am taking that test in a couple of weeks. I have passed it before but my QA department dropped the ball on keeping up with my weld qual. Lately have been struggling with lack of fusion on all of my welds that get RT'ed and curious if someone can point me in a better direction.

-------------------------------------------------

weld a little hotter with a tighter arc. and always plan one bead ahead so you dont trap yourself in that last bead in a layer that traps slag and causes lack of fusion.

sounds easy but when you are trying to constantly reposition yourself on a 3" 6g test, its not easy to hold a consistent arc.
