My mistake. I should have looked at the date on the post.
Oh no! My bucket is broken!

Oh no, it is definitely a real thing on a ship. It has to do with the steel being reinforced with T-Bars, which are naturally T-shaped. When you get into corners and decks, its natural that those T-shapes make it impossible to see into those goofy corners, so a mirror must be used to see instead.
Incidentally the 100% welded rule for naval ships has nothing to do with strength. It has to do with longevity. If a seam is 100% welded, it cannot have rust start to form where the two pieces of steel meet, and otherwise would not be sealed with a weld. They figure a fully welded ship lasts about 20 years longer then a stitch welded ship because paint and sealants help keep out corrosion.
Obviously there are critical welds on a ship, and those are x-rayed, or use other non-destruction testing.
Interestingly, there are sections of a ship that are welded in a way that they will fail. That way if there is an explosion, the force blows the ships OUT and causes less damage. Its not a bad weld that does this, just undersized steel...like a crumple zone in a car.
But I never forgot that 300 sailors lives depended on my welds, or that the ship could see battle, or 50 foot seas.

Broken Track,
Thanks for that information. Back when the guy told me that, I was a welding school dropout and he had left welding and gone into retail. I sometimes wonder if he went back into welding.

Good job!
It probably doesn't matter, but I always try to leave the craters in the middle of a weld, or in this case as far away from the start of the ripping action.
That is exactly what I was thinking when I saw the weld. I either weld from each side to the center, start the weld from the side with the most strain or in the case of a multi-pass weld, stagger my starts by welding in one direction, then next pass start welding from the opposite side. This tends to keep the welds even and reduces the possibility of a crack starting at the stopping point of the weld passes.
