That is one ugly weld or two, But you do have to give the man credit he most like from the looks of it had to do the repair while under way with pressure in the line and looks had very little to do with it. lets hope so anyway.

the top picture looks like it was welded with a bare rod.

I wish I had been allowed to have cameras in a lot of the places I have worked in my 20 years in the USN.  You guys would think better of the above pictures if I could show you some of the crud I have seen, both from military and from civilians, contractors and yardbirds.  True story.  When I was in USS Camden in Todd Pacific SY, the burners came down to remove a sounding tube from a fuel tank one night.  They got the whole thing out, then someone realized that they removed the wrong tube.  Well, those burners got it in mind to come back to the ship before the end of the shift, grabbed a powercon and a handful of (probably) 6011 and "welded" the tube back in...from the 6th deck all the way to the top, in 3-5 foot sections.  Then they painted the thing and no one said a word.  Couple months later, we're out at the fuel depot loading some 4-5 million gallons of DFM and JP5, and the bells go, flooding.  Guess where?  Two lower magazine decks (empty) flooded completely with JP5.  Had to strip all the anti-static flooring out of both and redo completely.  What a mess.  So don't go saying that the squids jacked those welds up; sometimes we have help. :)
