Looking for facts and opinions on this topic.
I'm aware that most welders prefer/do hot pass with 6010 for its cleaning characteristics and so they avoid blowing through their root.
I'm aware that putting in a hot pass with 7018 can be more prone to slag inclusions and incomplete fusion depending on how the root and subsequent grinding of the root went.
When a WPS has a root pass of 6010, that has a max deposition of 1/2"thick, and the fill/cap requires 7018 would/could you justify a hot pass with 6010 as long as it does not surpass the thickness allowed? Or because the WPS does not specify hot pass 6010 it can't be done legally.
Facts and references are great. Previous experience/resolution of this problem would be even better.
Thanks for your input.
