I don't have to stand at a forge to know heat ... when you make thick multi-layer welds in high summer ... it gets similarly hot.

But you have to cover your whole body because of the electric arc - I have already got many a "sunburn" on exposed (uncovered) areas.

I do welding, too, though I don't do big stuff. I just weld metal rods to the ends of my billets, so that's not really a problem for me.

Quote

I also know Dave Baker ... he often shines with his very extensive background knowledge of old weapons.

Well, that's something he and I have in common. I love studying old weapons. Many of the weapons I forge are from ones I studied, like the claymore. Other weapons I've forged from history are a Viking sword, katana, and zweihander. I also forged a few knives, with my favorite being a recurve. A recurve, when done right, can do almost anything, like stab, slice, and chop.

As you can see, I haven't dome that much forging, but now that my bitch ex is gone, I plan to do A LOT more. My next project is going to be from fiction: the Nordic sword from Skyrim. Kalyna wants one for a cosplay she's doing and can't find a good replica, so I'm going to make one for her.

there is already a bit of materials science involved ... There are also many types of steel (or other metals) for welding - with which you have to do a special heat treatment.

What I meant was, "It's not that hard to understand".

My grandfather learned metal working from a job he had, and he taught me about it. In fact, he gave me the anvil I use for bladesmithing for my 20th birthday.

[Miauzi]

Gerade eben sagte deadjester226:

Mein Großvater hat beruflich die Metallverarbeitung gelernt und mir das beigebracht. Tatsächlich schenkte er mir zu meinem 20. Geburtstag den Amboss, den ich zum Klingenschmieden verwende.

 

You were very lucky... with your grandfather.

I "only" learned tailoring there - in the way that my grandparents' profession (3 out of 4 were tailors - one was a master electrician) inspired me to teach myself many things.

In my school years I learned many things about metal and woodworking ... as well as electrical engineering - that was part of the education in our school system.

It helped me later as an engineer with many things ... Things that I designed - I could also build myself

except for blacksmithing ... I was too young during school.

(We were taught the manual skills in industrial companies ... so I was in the locksmith's workshop at the age of 13-14 ... I wasn't allowed to work at the forge then - unfortunately).

So I can fulfil my dream ... to be able to forge ... unfortunately only in the form of my Skyrim story.

At the beginning it's more blacksmithing than fucking ... sorry

The other small deep-sea diving boats don't have an escape hatch either - there's no room for one anyway.

But what is fundamentally different with them ... the hatch can be opened from the inside as well as from the outside and is arranged in such a way that it can be opened at the surface - without the interior filling up with people.

Whether the carbon-fibre fuselage failed or the bull's eye (viewing window) or something else led to the implosion... it doesn't matter ... because, strictly speaking, it shouldn't even have survived its very first dive ... so flawed was the design AND manufacture of this diving coffin!

He deliberately did NOT hire experienced people with the professional background of naval submarines (there are no others) - because they would have swum to the end of the world after the first dive at the latest ... no - he deliberately wanted people who had absolutely no idea about this field. That's why his team couldn't recognise their junk as such and sell the paying guests that the other dive boats are as (dilettantish) as theirs!

---

Even if he had only used steel or titanium for his scrap bucket ... the many small and big incidents ... of which more and more of his former guests report ... would have been his and the respective crew's undoing at some point.

As an engineer, I have only ever had one project together with a certification company from the shipbuilding industry ... but I know from working with these people (Germanischer Lloyd) - that they help you when you are faced with a technical or design problem ... with their own approaches to solving the problem and the experience they have gained from other projects.

He deliberately left that out - he ignored it in his arrogance and arrogance. In the end, his failure was even predetermined ... Fortunately, he was on board and no one has to endure a justification aria from him now!

 

PUNKT

 

A little more than "punkt", I think:

It was part of my dive master training ... even if we never dive as deep with breathing apparatus as the people in the submarines.

is a relatively quick death ... But you don't find corpses anymore ... with such small submersibles

different when nuclear submarines or "conventional" submarines implode ... depending on the depth at which this happens - body remains can still be recovered.

if what my wife and I have been able to gather from the net so far - the disaster journey was only the fifth he had ever undertaken to such great depths (to the Titanic).

Keine Ahnung, ob Ihre Aussage mit mir übereinstimmt oder nicht.

Wie auch immer, das Letzte; Hier scheint Rush damit zu prahlen, gegen die Regeln verstoßen zu haben:
 

Warum machen Sie nicht Kohlefaser und Titan? Galvanische Korrosion. Die beiden passen nicht gut zusammen, und wenn man ein Medium hinzufügt, das nicht gut zusammenspielt, wie zum Beispiel Meerwasser , wird es VIEL schlimmer und die Dinge korrodieren VIEL schneller. Oh, und Kohlenstofffasern werden von Natur aus dadurch hergestellt, dass Dinge, die nicht zusammengehören, zusammengepresst werden, normalerweise unter Verwendung ziemlich hoher Drücke. Na gut, aber werden Sie den Druck des Meeres übertreffen? Zweifelhaft. Und wenn das Meer siegt: sofortiges und völliges Scheitern.

Dies ist die Art von Gespräch, die mich persönlich dazu gebracht hätte, schreiend davonzulaufen und mich so weit wie möglich von allem fernzuhalten, was dieser Kerl getan hat. Bei den Regeln geht es nicht nur um Bequemlichkeit und darum, „Neulinge fernzuhalten“. Wie man in der Luftfahrt sagt: Die Regeln sind mit Blut geschrieben. Jemand ist gestorben, sie haben herausgefunden, warum , und dann haben sie eine Regel entwickelt, um zu verhindern, dass dieser bestimmte Grund/diese Todesform erneut auftritt.

 

Please look at the shape of the pressure bodies of such extremely deep diving boats ... what do you see? -> The BALL SHAPE

what did this "gentleman" choose? -> a cylinder with half-spheres at the ends

With this he has already determined the constructional weak point in terms of "pressure distribution on the envelope surface" -> the transition from the rounding of the sphere to the flat surface of the cylinder (longitudinal section) ... and exactly there is also the connection point.

There is a video on the net that shows how the "front" ring is glued onto the cylinder ... WITHOUT an autoclave - which massively reduces the air bubbles from the glue.

When I saw this ... I, as a Facg-Ing. of Welding - who is of course also trained in other joining processes ... including bonding - I grabbed my head with both hands and was completely stunned!

---

How and when do the "guests" and the "crew" get into the boat?

on the "platform" that has been lowered into the water ... which, depending on the swell, can sometimes be heavily washed over ... I saw a video on the net last night

yes - they really wear -> RUBBER BOOTS ... which they take off when "climbing" the boat.

Well I'm certainly not disagreeing with you. Mine is more of a half interest. I'm looking at motivations not outcomes as the outcome is self explanatory(Although the outcome of being attacked by an eldritch sushi monster would be a much better story but I digress.) When it comes to motivations whether it be passion or business there is always a rush to push a product out the door whether or not it is ready. While I can respect trying to challenge the status quo it sounded like he didn't test it in controlled conditions enough to make that challenge worthwhile and now he's dead.

Actually none of that even matters. The glass aka the weakest area of the sub's tensile profile was rated to handle gpsi at 1300 ft/d ; the sub imploded at 4000 ft/d. The man literally had no idea what he was doing and thought he could out-money physics.

BINGO!

My very first thought was Alvin.  You look at the schematics for that vessel, and it's clearly a sphere, with a hatch that is designed in such a way that it seals tighter as external pressure increases, and all the non-essentials arrayed around it (propulsion, lights, etc.), not to mention the comparatively tiny viewing port.  Alvin was one of the first manned submersibles on the Titanic wreck site in 1984, and Alvin is still in service today!  Oh, and Alvin's rated depth is far greater than Titanic's depth, so it wasn't even close to pushing safety limits for depth on that wreck site.

Found another video of someone pointing out that whatever the tested depth of a submersible/submarine, you never operate even remotely close to that tested depth, same as, when engineering something, you over-build it by a certain margin (he states overbuild by 100%, i.e. only operate at half the rated failure point).  More like half that depth.  Supposedly, this thing was tested to 4,000 meters, and was being routinely operated at 3,800 meters.  He also talks about how the lamination was done on the center section, with straight rows rather than a criss/cross pattern or some other, stronger, way of doing it.  Additionally, he talks about, as others have, the stresses of compression/decompression on the hull.  Elsewhere I've seen stated that they never did test the thing between dives to test for problems.

Mein allererster Gedanke war Alvin . Wenn Sie sich die Schaltpläne für dieses Schiff ansehen, handelt es sich eindeutig um eine Kugel mit einer Luke, die so konstruiert ist, dass sie bei zunehmendem Außendruck dichter abschließt , und allen unwesentlichen Dingen, die um sie herum angeordnet sind (Antrieb, Lichter usw.). ), ganz zu schweigen vom vergleichsweise kleinen Sichtfenster. Alvin eines der ersten bemannten Tauchboote auf dem Wrack der Titanic und war 1984 ist noch heute im Einsatz! Oh, und Alvin die Nenntiefe von ist viel größer als die Tiefe der Titanic , sodass die Sicherheitsgrenzen für die Tiefe an dieser Wrackstelle nicht einmal annähernd überschritten wurden.

 

 

Ich habe ein weiteres Video gefunden, in dem jemand darauf hinweist, dass man unabhängig von der getesteten Tiefe eines Tauchboots/U-Boots niemals in der Nähe dieser getesteten Tiefe operieren sollte auch nur annähernd , genauso wie man bei der Konstruktion etwas um eine bestimmte Spanne überbaut (er gibt an, dass man zu viel baut). 100 %, d. h. nur Betrieb bei halbem Nennausfallpunkt). Eher halb so tief. Angeblich wurde dieses Ding bis zu einer Tiefe von 4.000 Metern getestet und routinemäßig auf 3.800 Metern betrieben. Er spricht auch darüber, wie die Laminierung im Mittelteil durchgeführt wurde, mit geraden Reihen statt einem Kreuz-/Kreuzmuster oder einer anderen, stärkeren Vorgehensweise. Darüber hinaus spricht er, wie andere auch, über die Belastungen des Rumpfes durch Kompression/Dekompression. An anderer Stelle habe ich gelesen, dass sie das Gerät nie zwischen den Tauchgängen getestet haben, um es auf Probleme zu testen.

James Cameron dived to the Titanic dozens of times with a submarine from Russia - it was developed and built before the end of the Soviet Union.

It was also used to transport the first tourists to the Titanic.

Officially, the "Mir" dives 5,000 metres deep - but the designer tested it himself at the deepest point in the Mariana Trench (approx. 11,000 metres) - alone - because he did not want to drag anyone with him to certain death in the event of an accident.

Submarine constructions are complex and therefore very costly to maintain

but that is necessary to guarantee a minimum of safety.

Yes - diving with such equipment will continue to be very expensive.

In the 1950s and 1960s there were dreams of a huge boom in diving technology and "life under water" ... but the various problems in reality have put an end to this...

...through my own diving I know about some of these problem areas from my own experience (deep intoxication, cold, decompression, panic attacks, inflammation of the external auditory canals etc.).

Others I know from documentaries and technical books ... and can understand them with my knowledge of physics, mechanical engineering and welding technology.

---

Yes - you can also design a pressure chamber for such great depths that is not ideally spherical ... but then you must at least remain HOMOGEN in terms of material and choose much greater wall thicknesses.

Which then means significantly more weight ... which again has to be compensated for with buoyancy bodies.

Is feasible ... but means an enormous increase in costs ... Laymen can only imagine this with difficulty.

There is a reason why high-pressure technology (over 200 bar = 2000 metres water depth) is not an everyday topic.

That was another thing that he flatly ignored: Using two different materials that contracted/expanded at different rates.  I've heard "some" speculation that had the thing been built of all composite, with everything moving at the same rates, and even given the horrid properties of composites for such a task,, it might have survived - this trip.  But then, you run into "Just how many more trips could it have taken before failing?"

Gotta agree fully with @27X on this:

Das war eine weitere Sache, die er völlig ignorierte: die Verwendung von zwei verschiedenen Materialien, die sich unterschiedlich schnell zusammenzogen/ausdehnten. hätte, wenn es vollständig aus Verbundwerkstoffen gebaut worden wäre, wobei sich alles mit der gleichen Geschwindigkeit bewegt hätte, und selbst angesichts der schrecklichen Eigenschaften von Verbundwerkstoffen für eine solche Aufgabe. Ich habe „einige“ Spekulationen gehört, dass das Ding diese Reise vielleicht überlebt Aber dann fragt man sich: „Wie viele Fahrten hätte es noch dauern können, bis es scheiterte?“

voll und ganz zustimmen muss ich @27X Da :

 

 

 

you can work with inhomogeneous materials ... but you have to design the details of the joint differently than he did.

Such things were part of my training as a welding engineer - in my first years of work I often had very exotic material combinations - especially in terms of expansion coefficient.

But if you already have a quite complex construction ... why add another detail that is complicated to solve?

You only do that - if you don't really know what you are doing!

The amount of mislabeled porn is staggering.

 

If you label something as lesbian and there are literally no vaginas in the entire video, only guys and guys with tits, I'm going to have to draw the conclusions...

1. You're uploading stuff only in the vain hope someone will accidentally click something on your site, and you'll become 0.03¢ richer.

2. You've never been laid or even seen what a womans body looks like.

3. You're brain damaged and shouldn't have access to anything more dangerous than a dull crayon, and even then, only with supervision.
