Aluminum foil to save weight.
If not, this is what my escape pod looked like when I was still welding it. I put the camera on a fence post, on self-timer, and ran over to the boat.
They are sexy and fast and these electronic marvels are great for showing off at boat shows but won’t survive combat and don’t do so well in a canal transit.
By the way, Travis, I grew up within walking distance of the Bahia Mar Yacht Basin.
I’m still hoping to see “The Busted Flush” some day.
This thing probably can’t face a kid with a slingshot.
How did the x-rays come out? If slag was there why didn't they grind it out and re-weld it!
... the metal would bend to its yield point like taffy before a weld would crack.
Same as in the petrochemical field. The pipe tears before the weld breaks.
The weld should be stronger than the metal around it. In common practice the exterior weld hump is ground flush, but on the inside, the extra weld metal is left “proud.”
When I went to welding school, to pass on aluminum MIG welding, we had to weld a plate, cut it into strips so the weld was in the middle of the strips, and them bend them in a hydraulic press until they were shaped like a hair pin, with the weld dead center in the middle of the bend.
If that weld failed, the welder failed.
That said, it’s hard to do a great job welding aluminum in filthy shipyard conditions. Any stray dirt or dust is sucked into the molten weld metal and turns it into a shit-alloy. You have to be extremely meticulous, welding aluminum in a shipyard (as opposed to on a clean workbench).
Still, this is not unknown, and the pitfalls of welding dirty aluminum are very well known: BROKEN WELDS!
UNACCEPTABLE ON A WARSHIP! UNACCEPTABLE!
Slip F-18. The Busted Flush.
The Navy has had a terrible decade with shipbuilding. Not enough oversight, as in the El Paso debacle. HUGE UNFIXABLE MISTAKES are welded in before they are found, when it is too late to fix them.
Timber probably was what hurt that beer can .....
“Rarely is the question asked: Is our government learning?”
Its that Lowest Bidder syndrome again coupled with the contractor most connected. Not good.
"How DOD Torture-Tested Its New Aluminum LCS" -- by banging it on the walls of the Panama Canal.
You said what I was thinking.
“....by banging it on the walls of the Panama Canal.”
Thanks for the chuckle.
Give a decent shipfitter a torch and he can cut anything out. Welders cry too much. {;^)
Agree completely.
Also, speed limit in the locks is 3 kts. This isn’t a supertanker. Sounds like the rudder got stuck hard over or something.
This doesn’t sound right at all. It is very hard to hurt yourself in the locks unless you have a mechanical problem.
The interesting thing is Ford spent billions of dollars figuring out how to make aluminum body panels for its trucks. This change was forced on the auto makers by the government — the SAME government that simply cannot make a satisfactory aluminum ship.
You see the counter coup video out yet?
