Need some opinions about these welds

I just had a cast aluminum oil pan welded up with the modifications I need for a new build, as you can see he has done nice work, the welds don't leak with pan holding methyl hydrate or hot water.

All welds were done on the outside of the pan with a 1/2" steel plate bolted to the pan to keep it flat.

What I'm concerned about is the inside of the pan or the other side of the welds.

I can't have the inside seams of the pan welded with out the risk of twisting the pan so I'm wondering if I should fill those seams with a flexible sealer like Three Bond or Permatex.

Or maybe I'm over thinking it...

The only thing I would worry about would be the possibility of some swarf being hidden away in the cracks and dislodging later.  Your pickup screen should catch most of that but still.  Glyptal would be the only thing I would consider if I wanted to put anything in there.
