- Explosion cladding is a solid state welding process that uses precision explosions to bond two dissimilar metals while retaining the mechanical, electrical and corrosion properties of both.
This is a clip from Modern Marvels.
i think i got everything i need to know to try this at home. thanks
How’d she go?

Genius. Funniest comment in recent memory.
"I wonder if there's a way to join these two metals together.."
"Lmfao let's just blow them up"
We have a shop in my town that does blast welding. It's hilarious when out of towners are visiting during a blasting day.
It's kind of counterintuitive that an explosion actually creates something instead of destroying it
We owe our lives to a massive explosion. 😊
Big bang.
On the contrary. Commercial explosive create not destroy. like a saw blade ripping into a sheet of plywood, It's finish can be a fine piece of furniture. The power of explosives build mighty dams that power our cities, Mine minerals such as steel, copper, aluminum, coal to heat and build out modern world, pierce and fracture oil well casings to increase the efficiency of extraction and so on.

For sure -- it does seem like this process is an oxymoron. But! In fact - our custom composite metal solutions would not be possible without the explosion from our DetaClad process.
When you thought that welding couldn't get any cooler.
Or hotter.
Or brighter
Or dangerous
We are biased, but we think the explosion welding process is pretty neat.
Don’t think this is welding. More akin to brazing than welding, I think. Never heard of it before now though. I am getting old. Not saying this process is new, just that I’ve never heard of it
Fascinating!
Great visualisation
Now the million dollar question... what are such special welds (or the resulting parts) exactly used for? Seems like this process is very sophisticated and expensive, so there must be some good reasons...
I think that it is because certain thicknesses of plate steel are not sold so with this method they can create any plate thickness they desire
No incorrect...this is used on infrustruces that chance metal...on tug boats where the boat is steel and the pilot house aluminum....they use this and weld the pilot house to the top aluminum portion
Few surface material properties are required in ballistic missiles, space programs, etc.
If one wants to weld tantalum and steel, this is a cost effective way.
Aggregate mining.
It's also used to make transition plates used it electrical power systems. To connect copper to aluminum you use a transition plate that is aluminum on one side and copper on the other. Copper and aluminum don't work well together and a transition plate solve the corrosion / galvanic action issues when joining the two. Look up electrical transition plates.
Nice explanation
Wow this is cool
Thanks you
FANFREAKINGTASTIC!!!
3:13 Lauri & Anni, listen up: he's got a 3'000'000 lbs press...; )
That's not that big. There are plenty of greater capacity than that.
We 've just bought some clad steel at NobelClad for Heat exchanger manufacturing. Very good product
I'm actually very curious about something I'm guessing you know then - how do you butt weld such material? All I can picture is welding rod that's like the Smuckers peanut butter and jelly jar but that can't be right, do you just use the correct filler metal for one layer to do passes until you get to the explosion weld seam and then switch to the other filler metal and hope that the lack of bond between the two layers won't be an issue on such a small area?
@@kenstein You have to remove (by machining) cladding from base metal weld areas. After butt weld you have to overlayed weld areas using electrodes matching chemistry of cladding.
@@boutchamos interesting, thanks. Pretty much what I expected
Their stock ticker is BOOM
Would be interesting to mention the end uses of this finished product
What happens to the spacers that are tacked on before the cladder is placed on top? I didn't see mention of them blowing out of the gap during the explosion, but they don't appear to be embedded into the metal.
I was wondering this too, down below they say "Caleb, There is a very high energy jet formed by the collision between the two metals, best seen from 2:14 to 2:40. That jet drives the spacers we use to keep the plates separated out from between the metals." So it seems they do get blown out by that high velocity wind.
@@chashahjohnson @tpaairman Correct! The jet from the explosion 'pushes or blows' the spacers from the pack.
Awesome
This is how you make reactor shielding i believe
@spikedpsycho i was referring to making clad via explosion welding of large pieces
word for word from modern marvels or is it the other way around lol
so fricken cool.i was surprised that the two plates were seperated. do the studs become part of the weld or are they removed by the rush of air?
Caleb, There is a very high energy jet formed by the collision between the two metals, best seen from 2:14 to 2:40. That jet drives the spacers we use to keep the plates separated out from between the metals.
Care to explain in more detail?
Everything from rust, oxides, etc are removed from the jet. It essentially "sweeps" the plate clean, which makes it ideal for a weld.
The spacers are shown being spot welded to the backer. Are you saying they are blown out of the gap during the explosive process?
@@phiksit Even if they weren't expelled, I doubt it would seriously harm the integrity of the weld. You have to remember they stated this type of welding can meld very dissimilar types of metal. I don't know what they're using for the spacers but even if they didn't get blown out by the extreme pressures of the escaping gas, which I doubt, they would simply become part of the weld.
Do they clad titanium to various metals for corrosion resistance?
Yes.
Yes - we do. We have also worked with Zirconium and Tantalum for corrosion resistance.
Some guys get all the good jobs...
What happens to the standoffs? Are they embedded in the alum.?
This is how we'll build starships
Learnt something new
Glad to know you learned something new! If you'd like to learn more visit our website: www.nobelclad.com
Wonder if scoring the 2 meeting surfaces to give them more surface area would yield better result.
Yes - indeed. Grinding both plates is part of our process. This helps remove any debris or oxides from the surface, which assists with the weld.
What is the purpose of joining two separate plates when you could have one solid plate? Is the top piece of metal the "important" piece, and this a more cost effective route due to the overall thickness?
Steve, you are on the right track. Usually the two metals each provide some advantage that one metal alone doesn’t have. For instance, some corrosion resistant materials are expensive or maybe not very strong. On the other hand many carbon steels can be specially designed for high pressure boiler and pressure vessel applications at a reasonably low cost, but they may not have the best corrosion resistance. Combining the two into a clad plate, and eventually into clad equipment, can give the advantage of great strength, long life and superior corrosion resistance at a lower cost than one solid material alone.
I have used this material , aluminum welded to steel where we needed to connect an aluminum top side,ie. cabin/wheelhouse to a steel ship hull/deck.
Wouldn't the metals corrode due to being dissimilar metals?
@@sablefisher Absolutely - that's a great use case for ship building.
What industries use explosive welded dissimilar metals and on what equipment?
We support a variety of industries like Oil & Gas, Chemical, Transportation, Marine & Defense, Power Generation, and Aluminum Smelting. The end use equipment is usually pressure vessels and heat exchangers that need to be corrosion resistant on one side and have steel on the other side for strength and durability. We also supply a lot of clad material into applications where corrosion and pressure containment are not primary concerns. Transition joints - transitioning between structures made of different metals or making electrical connections between metals that cannot be otherwise welded together is another interesting use of our clad.
Our products end up in a variety of industries: Oil & Gas, Marine, Defense, Transportation, Chemical & Petrochemical and more. In terms of applications explosion clad can be used to fabricate pressure vessels, crystallizers, heat exchangers, condensers, transition joints, etc.
It's the only way to weld the aluminum superstructure of a warship to it's steel hull, for one.
Yeah, I've heard of it referred to as Detastrip or Detacouple. Usually comes in long strips two inches wide.
I imagine the cost is prohibitive outside of major industries and companies with very specific need for such a process.
what may be the pressure developed during the process
hundreds of thousands to millions of PSI. It is an explosion after all.
Wait a second: why the welding in the first place? Couldn't they just provide a thicker steel plate? Or is there some unique advantage having two plates welded together?
Thanks for the questions! Actually in instances where the processing environment is too corrosive for a solid stainless steel or carbon steel, clad is used. When there’s high temperatures or high pressures, corrosion resistant alloys are explosion welded to stainless steel and carbon steel. The idea here is that multiple metals explosion bonded together achieve additional, functional benefits unachievable with a single metal.
In some processing environments, leveraging a corrosion-resistant metal is very expensive. It is not cost-effective to make an entire vessel out of titanium or zirconium. With DetaClad, you can leverage a thin layer of Ti or Zr welded to a Steel or Carbon steel as a composite, more cost-effective solution where the equipment doesn't need to be replaced as often if a solely steel was used.
I wonder when yt algorithm will bump it
Is this located in Dunbar, PA?
Our manufacturing facility is located in Mt. Braddock, PA and the mine is located in Dunbar.
was this process accidently discovered?
Pretty sure they invented clad rolling and friction stir welding first, then moved to high explosives where clad rolling is impossible.
WW2 shrapnel sticking to armour plating and welding on. They figured out it was the explosive force not heat
How do they well that together?
Hi Andy! Thank you for your interest. Our proprietary explosion welding process, DetaClad™, bonds two dissimilar metals from a high energy jet formed by the collision point as seen from minute 2:14 to 2:40. To learn more, visit our website www.nobelclad.com
the only question i still have is what application requires the end product? what application requires a thick plate of two different types of metal?
Military,explosion welding was first noticed on warships in ww2.
@@brianbaker8287 to answer OP’s question, Clad is used in oil refineries among other industries where corrosion is prominent
Never asked that was Tom,but I'll play along ,Battlefield armaments-Tanks
Typically anywhere you have corrosive chemicals under high pressure. The backer plate is what takes most of the pressure while the cladder plate protects the backer from the whatever corrosive chemical is being worked with.
Here are some examples: Our DetaClad plates and tube sheets are used to fabricate pressure vessels, heat exchangers, and reactors in oil & gas, chemical, or energy processing environments. Our transition joint components can be used as piping junctions in LNG or air separation units or to join aluminum to steel hulls in shipbuilding. The equipment application list is pretty expansive pending the temperature, pressure, and corrosion parameters of the environment. nobelclad.com/industries
Can explosive welds with ground up lava rocks and onyx be used with appropriate materials to combine into something that could be used to break Apart an 5 million lumen light through a inverted lumen prism solar panel
I mean if you put an aluminum core that 90% that is cooled through a super cooling system would hold up right
Dude imagine a hovermansteamcraft displaying a purple sphere in the shallows at 500 million lumes
At this time, we do not use material with ground-up lava rocks!
What sort of tooling or other things are made from explosion welded materials?
The coins in your pocket and tanks at oil refining facilities.
also the copper-stainless cooking pots.
@@EricThompsonClimber Coins aren't explosion-welded. Jesus, can you imagine? Pennies would cost dollars.
@@magicponyrides dont worry.
Inflation will take care of that.
@@pyromaniac354 But will it?
So what manufacturer on gods green earth would need plate like this? 5 inch thick multi alloy stacked plate? Like what is this used to make? I need to know.
Great question! Our direct customers are fabricators, ship builders, smelters. So for example, we would send a clad plate to a fabricator who then constructs those plates in to a pressure vessel or column.
Most likely military…

Is there any adhesive material between two plates
No, there is not any adhesive material between the two plates.
No - there is no adhesive material between the two plates.
Helps me understand how this planet was formed.
lmao you actually believe in the big bang theory?
@gasbaroni How about we play a game: the first one of us to make 3 solid points about universal or planetary formation wins. I'll let you go first since the big bang theory is funny to you.
@@trials6502 I'm not the one who blindly accepts the big bang theory, the burden of proof is on you. How do you explain what came before the big bang? How did something come out of nothing? How did the laws of physics come into being? Not our subjective understanding on what they are, but they way they objectively operate on their own. There are no definite answers to these questions.
@@gasbaroniStill nothing yet. Amazing. No one made mention of the big bang theory but you. A mess of assumptions and shifting.
How did our planet form, or universe. Still got 3 chances.
Is it a true weld though? You’re basically smooshing it on with an explosive breadroller.
It's more like soldering because at least one of the two materials stay solid, here both of them are solid.
@@johntheux9238 It is not considered soldering nor anything close. This is a weld; Solid State Weld to be exact. Soldering and brazing are forms of "gluing". This is considered Explosion Welding. As stated above, Explosion welding is a solid state weld, meaning there is no fusion of materials at the bond zone. Fusion welding is MIG, TIG, Stick, etc.
Explosion welding share electrons at a depth of about 30 nano-meters (If my memory serves correctly)
@@liveunlimited8112 Makes sense since solid state welding also works with identical materials even if it's often unwanted (like for spacecraft components which have no oxyde layer protecting them from each other)
@@johntheux9238 are you on drugs? LOOK UP the definition of soldering/brazing. There is no low-melting point filler involved here! JFC
@@railgap And you should look up at the definition of welding. Both pieces are supposed to melt together. Here they stays separated, like soldering/brazing.

I'm studying welding ,But i don't understand this video. Who can explain please?
The two metals are welded together by the shockwave of the explosive compound, the upper layer (cladder) which has the explosive on top is forced downward so hard and fast that the molecules of the two materials fuse together. The two plates slam together so fast that the inner surface of the two plates liquefies and incorporates into the other. The little metal spacers they spot welded between the plates provides enough room for the cladder to gain sufficient velocity to allow the welding to occur (If the two plates were touching together they would just deform instead of fusing together), and are spit out along with impurities and oxides present on the surfaces that would otherwise inhibit the weld.
or they could just have an average McDonalds frequenter walk on it. Same kinds of pressures.
