Mmm, the one you've shown doesn't look so bad in close up. Bit messy, but flux-core always looks a bit messy, I use it myself. You can never get it looking as nice as a gas wire weld, but it is just as strong if you make a good job of it.
I was a bit worried about the welds in one or two of your pictures showing what looked like a few tacks around the pipe, rather than an almost continuous seam, and some looking like they were sitting on top. Some of this could be slag if you're using flux-core, of course, or just due to an out-of-focus picture.
If you have really tested them well they should be okay, but there's always an element of guesswork if your machine isn't working properly, and having seen one or two nasty accidents I tend to come down on the side of caution.
The pic below shows the areas I mentioned. The blue arrows indicate what look like tacks, and the black arrows indicate what look like missed areas. You may be able to examine these areas and assure us all is okay; the welds will probably show up better when wire brushed.
