Looks very nice. Welds don't look ground, they look like they were either fused without filler or keyhole plasma or similar, except the fillet. Fusing works very well to save on finishing/clean up. I don't trust it generally for IC piping, but thats just me, I have seen pipes in production that use it so it is likely fine. However it was done, the fitup work is really nice etc.
