You can learn something new every day.
This scared the shit out of the local cars!
Now I know what I can try on Sunday morning.
You'd have to be completely confident in your welds. 8)

I suppose this both forms the sphere and pressure tests the vessel at the same time! :rofl:
Wow, that was an amazing demonstration. That sphere looks perfect. I wonder how they made it prior to hydroforming.

It is a simple task, because any curved 3D object can be made from flat faces or facets. I see each sphere is welded up from, in this case, only 7 flat sheets of steel. I guess seven is optimum for the size of the explosive charge they are using and the thickness of the steel. Fewer faces would require bigger explosions. More faces would be overkill, as they would need lower charges, but more time and work to assemble.

Automatic QA!
what are they?
mooring buoys?
I'm guessing LPG containers.
Those are obviously the metal eggs of huge robots. These are commonly found in manufacturing plants robot breeding grounds and that is how we make more robots for industry. It is known.

Or giant robot testicles?
I'm asking for a friend,
what is the point of it?
Does it make the subject stronger, or is it just cosmetic?
Volume is increased, and stress is more evenly distributed across the skin surfaces. Flat plates are much easier to bend or dent than the compound curved shape of the sphere
The blasting media is submerged in water when initiated. Water is more dense and can have more dynamic force to distend the previously flat panels of the vessel.
Many moons ago I was in military demolition school. Our mission as Coast Guardsmen was mostly to disarm enemy devices such as torpedos and mines. We were also instructed in some of the methods of espionage. We tinkered with what was then called "shape charges". Imagine a sheet metal cone about the size of a souffle cup. Fill the cone with a suitable explosive such as Composition C. When fired the little device would make a neat round hole in steel plate. Other shapes of sheet metal containers could make different sizes and shapes of holes.

okay, you can't leave this alone.
i want to hear everything you have to say about this.

:o They're harvesting giant robot
testicles now? What has the world come to? ::)
