This is like a much cooler version of when I get the first coat of primer on and can see how poorly I did patching drywall.

Ultrasonic thickness testing (UT) was common in the 1980's. There would be no need to drill holes to measure overall thickness. Individual deep pits are more difficult to characterize with UT and might have been drilled out and patched. But A more common area repair would be surface grinding followed by a weld overlay, which is what you observed. If during grinding, the plate was ground completely through, they might have welded in a patch instead. (Retired Engineering Duty Officer)

[@SeanBZA]

More like they drilled out coupons to take for testing, big enough to cut a dogbone test strip out of for a tensile test, and simply replaced the drilled out coupon with premade blanks of new steel. Those are not corroding because they are made of a newer steel composition that is much more corrosion resistant, due to improved alloying over the decades. That the old plate is still there says the lab testing came back that it still met the original minimum tensile strength criteria, just had had corrosion, likely from either a paint failure, or from the poor anode installation previously. If the testing had come back as marginal that whole plate would have been cut out and replaced. There probably are a few that have been done like that on the hull.

[@jetdriver]

So if you had a perfectly circular weld repair on the bottom say about an inch in diameter (saw one of these myself) you would say that was likely a deep pit that was drilled out and welded up?

[@SeanBZA]

@@jetdriver That would likely be a pit repair yes, drilled down to the base of the pit, then welded up to the surface, and ground down flat. Drill to get all the rust out, and bare steel, then fill it up with weld.

[@twrecks4598]

I was a Hull Maintenance Technician in the Navy. What you are referring to is called a "base metal repair" where thinner areas of steel are built up with a series of welds, and then ground back down to spec.

[@lesjones5684]

Thanks so much ❤❤

[@trailrunnah8886]

It's funny how these videos on the simplest thing are still incredibly fascinating

[@robsalvv5853]

The pad welding process you are describing is called temper beading and was probably also used to add an element of heat input control. 3/4” thick steel of that vintage needs good weld precautions. This process ends up rebuilding the lost thickness with a good ductile weld that has reduced internal stresses and strains, reduces weld plate deformation and importantly, reduces the risk of embrittlement. I wouldn’t be surprised if they used a high localised preheat temperature as well to help slow the cooling of the weld which further reduces the internal stresses.

[@TXGRunner]

You should write this up and send a bill to the Navy for extra costs due to their slipshod work during '82/'83 and 1987 refits.

Yeah, because the paid staff were so busy with dry dock details, they ended up not putting out information to the public about the work being done. _U S S Texas_ missed an opportunity to get more people involved and more donations by not doing what Ryan has been doing for us.

It would be interesting if the museum could get someone from the dry dock to talk about how they would definitively repair battle damage. Like how could they replace armor plates, rebuild the bow and stern, rerun wiring, repair a damaged keel, replace piping, and so on.

[@richardgauthier2155]

A method to determine wear and corrosion in some metal pipe lines, is to drill or tap a predetermined location in the line and extract a coupon or cookie, a disc that be tested and used to determine the potential longevity and planning repairs or upgrades to the asset.

[@Cincy3]

I think I can speak for most of my compatriots who went to sea on Navy ships that these video's bring back a lot of memories. Thanks

[@josephbaker677]

In the iron mines in Minnesota. They rebuild and reface massive fans that move million`s of cfm. Taconite dust wears the fan blades like water erosion on stone. Welders come in and reweld mother metal, then hard face with "counted passes" to rebuild the fan blades. They look like the wind rows you see on the side of your baby.

[@SeanBZA]

You do not want to see what sewage does to pump impellors and volutes, it erodes them away sometimes within weeks. Same for water treatment plants, especially those pumps handling the chemical additives. They have redundant pumps all over for that reason, often a bank of 3, so that they can still handle full capacity, even while repairing the one failed one.

[@seldoon_nemar]

@@SeanBZA Bank of 3 so you have an operating, a standby, and a service at all time

[@SeanBZA]

@@seldoon_nemar They size so regular flow you only need the one, then have a pump capable of handling rainfall, which brings lots of water in as there always are people who divert rainwater to the sewers, and the third is a spare for that peak while one is out for service. The piping and flow rates are sized to handle 2 pumps at full output.

[@whatever8282828]

On this channel, but years ago, when I first heard Curator Szimanski talk about archeology of the ship I thought that was a bit of a stretched metaphor. But here we can see it is exactly apropos!

[@aserta]

Archaeology is an umbrella field of work. There's a metric ton of specializations under that word. Everything from social and historic (which usually don't even touch a trowel and brush) to experimental archaeologists (like the good folk over at Guédelon in France). Ryan falls between historic and field, and his specific application is "living" artifact. You could swap the ship with a castle (or any building), for example and have an idea of what that entails. That said, given how many dark places and damp holes Ryan has climbed into that ship (and some off it) and all the plundering and booty ... err, i mean, museum grade, historical materials that he has helped acquire for the ship, he gets a good mark in the field archaeology. Plus, the wooden deck was so rotten in places it had turned back to dirt, so if he has cleaned even one such spot, he's more than just honorary in that grade. :))

Based on the size of the beads, they must have shot tons of MIG electrode at the hull to build it up as fast as possible.

[@NorthernChev]

So, much of the 1987 dry docking seems to be fixing all the eff-ups from the 1982 dry docking….

[@crakkbone8473]

This is the best goddamn camera work I’ve ever seen.

[@justapeasant8949]

Iowa-class (and many others vessels) battleships were a wartime build. I doubt they wasted too much time on quality control. It was after Japan has surrendered and warships were drydocked that these build defects were discovered🔍

[@highstreetkillers4377]

When kids mess up machining a mold we do the same thing. Cover it in weld and machine it again. Someone there got lazy on the grinding, lol. No the welder should've came back and welded in the low spots and then grind it again. Then it'd be smooth. As long as you got good welders that perfectly fine. There is such thing as a laze welder also that will only add 0.001" to it. Thanks for sharing. Cause I like seeing how they do it on ships.

[@user-rz6ix1xj8p]

Not necessary to grind it down so it’s smooth as a baby’s a.. There were thousands of areas the required clad welding . I am sure that the Ship Supt. And navy engineers would have told someone to do as you state if they thought that it was required before they flooded the dry dock. Calling the welders lazy, is not called for unless you actually worked in a dry dock and have an understanding of the process.

[@fredinit]

@@user-rz6ix1xj8p Laze welder, not lazy welder. The first uses a laser to allow you to build up the bead in very small amounts. The second you want off your crew as they contribute to negative production.

[@user-rz6ix1xj8p]

@FREDINIT. Understand both meanings, thanks. I believe it was stated that someone got lazy, hence my remarks. Plus, i never saw laser welding done in a dry dock. Conditions would not be favorable. More of a shop method.

[@AldoSchmedack]

Rounds hole is a core sample or to cut out a section needing replaced, which I doubt it did. They use a plug and slowly weld it in to put back. It may also be to add equipment after it was made. Check your blueprints (wink).

[@AldoSchmedack]

One other thought, you may have it because when they decommissioned the ship, they took something out too....

[@hawssie1]

[@aamiddel8646]

Always interesting. Do you make detailed records of every inch of the hull (high resolution photos)?

[@charlesmaurer6214]

Just an odd thought, wouldn't those prior cleanout holes be good mounting points for some anodes. The prior long lines was in part to reduce drag on those blocks, being spread around more would provide a little more even protection, I would think. Also since they are already plugged holes you wouldn't be drilling into the unaltered steel.

[@SeanBZA]

The new aluminium anodes being installed are a backup for the much more effective impressed current system they have. Even the original anodes are mostly intact due to that.

[@RalphPapa-gq2hw]

My first ship, USS Springfield (CLG-7) ComSixthFleet Mediterranean Sea was scrapped there at PNSY I believe but have never seen any photos. Are you Ryan able to find out if there are any please? I am 3,948 miles away. Thanks

[@kirknelson156]

what I want to know is while its in the dry dock getting cleaned and coated what about the area where its sitting on the blocks, do they refloat and move the ship a few feet than pump out the water and continue with what they missed or can they move blocks one at a time to get at whats being covered?

[@janstransky442]

How much is the ship water line bellow the water level outside of the dock? When you will fleet the ship, do you have to flood the dry dock fully, or just enough that she rises from the blocks?

[@Colinpark]

1:21 really feels like I am looking at a photo taken through a microscope of cells and other stuff.

[@WardenWolf]

Is there any chance the Navy might have used something like Bondo to smooth it out that got stripped off with the paint? You didn't expect the caulk, so who knows?

[@highstreetkillers4377]

The welder should've came back and filled it the low spots and then you grind those highs spot to make it all smooth. That would be the proper way. But like discovering caulking the navy yard must be going cheap a lot. Which makes sense I guess

[@leftyo9589]

sounds like a lot of guess work going on!

[@philbudne2095]

at about 6:18 "riveted seems burst open"!! Did I miss an episode? I don't recall seeing an episode that mentioned results from ultrasonic testing either.... And I remember seeing one spot Ryan was able to remove large flakes of rust: what was the resolution there?

[@tomnewham1269]

Riveting seems bursting is what happened to the Titanic.

[@Marc83Aus]

There was a earlier episode where ryan discussed how riveted seams could burst open when repairs to the plating is made close to the seam, expansion of the plate from welding can put too much stress on the rivet, additionally there was mention of cases where welding the seam would be done but the heat of that weld would rip out rivers further down so more welding was needed, basically having to chase the seam as it unzips from being repaired. edit: It was near the end of the video titled "rust on the battleships hull"

[@watchthe1369]

Not the least bit surprised welding was done to thicken up worn plates. If you look ay mining shovels and other heavy equipment you see this done all the time. When the equipment is involved in "abrasive work" they often weld additional "hard rod" metal that is harder than the original bucket metal onto brand new buckets in wear spots. I would not be surprised if something similar was done, only with a more corrosion resistant alloy?

[@glennmcgurrin8397]

If it did have wastage would they not drill it out for a clean surface to repair?

[@riggsandmurtaugh7938]

Ok im gonna say that shipyards back then the last time it was in dry dock was to be decommissioned

[@WillieWanker8135]

A little bondo woulda fixed those up just fine

[@aserta]

What's odd to me... is the proximity of those clad welds... why didn't they just knock out that entire section and put a fresh panel in? It's a heck of a lot more work to clad weld and quite a bit more heat involved (unless they wait for cooling on each cordon). So they sure as heck didn't care about warping. Maybe i'm missing something here, but to me, from what i've seen over the years, taking a torch to the area and putting a new plate in seems faster and more economic. There's a lot less weld in a plate swap than there is in a clad weld and less work for the dock workers. And this isn't armor, this is buoyancy and streamline material. Weird.

[@SeanBZA]

New plate is a lot more work for the yard, they have to pull out the original drawings, cut and bend the plate, and then have to test the entire weld area for being watertight. Plus an ungodly amount of inspection, as well. Welding up the thinner surface just means you have a team of 15 welders running half hour work periods doing beads across there, and either a few tons of welding rods, or a few miles of filler wire for a MIG welder. Even in 1980 you had semi automatic welders, that could run a bead of weld in a line onto the surface, and automatically step up to run the next one as well. Set up on a clean ground surface, and let it loose, and have 2 people per shift feeding it, and cleaning the bead for the next pass.

[@user-rz6ix1xj8p]

There was no holes drilled in the hull to determine plate thickness. Plans and blueprints would tell you the thickness of the areas in question. Inspections took place once the ship entered dry dock , and the eye of the inspector, usually a planner/estimator would determine and annote the areas by frame and distance from centerline. a man’s hand would be used as a guage to determine square inches needed to be clad welded. A spread out hand would be approx 25 sq. Inches. Multiply that time thousands of areas that needed clad w., and you get a figure that translates into manhours necessary to accomplish the task. Certain areas would be Ut inspected(ultrasonic testing). 😮

[@kiereluurs1243]

[@user-rz6ix1xj8p]

Thank you @ypaulbrown for the defense of my grammar. Not necessary, but appreciated. I was just trying to point out how we did it at Philadelphia Naval Shipyard. Pitting is common on all ships, even with anodes. The best hull that came into the shipyard was Uss Kitty Hawk. It’s coating was an anti fouling paint that contained organotins if I am recalling correctly. But they had to remove it because of its harm to marine life and other environmental considerations. The removal increased the cost of the bottom job tremendously

[@SeanBZA]

@@BattleshipNewJersey Those are where you attach the tester, a nut or pre drilled plate with a thread, so you can get good acoustic contact with the parent steel under it. There will also be some places in the recording where they used gamma ray testing to determine thickness, as that gives a large area test that can be very accurate, even through the existing paint and anti fouling coatings. Just needs to be cordoned off during the test, and all workers out of that section of the ship

[@phillyphakename1255]

I love Curator Ryan talking mechanicals to me. "Non ultrasonic ultrasonic testing" and "uhhh ...micrometers?"

I dont get many opportunities on this channel where I know more than you, let me have this one!

[@hololightful]

Why repair the plate by such a labor intensive process? Why not just cut out the offending areas and weld in new plate?

[@highstreetkillers4377]

the welding is cheaper and is actually less work. Plastic injection molds get the same thing. Plastic erodes the mold in areas, you'll see that around a bleach bottle handle. The usual repair is to weld it and re-machine it. If there's grooves after machining it'll get welded again in those low spots and machined again. It'd cheap to do and easy. Like on the ship, if there's too much damage. Then you machine a huge pocket and make an insert to fit into the pocket to physical replace the area. Sometimes with a better material to resist the plastic corrosion. Just like patching plate on ships. That's expensive though, and on a ship I'm sure they'd then worry about it being watertight versus just thickening it with weld
