How They Make Stainless Steel Spheres

There has been a small clip of an explosive going off in large spheres in various video compilations on KZfaq late 2021. I did not know what the clip was or what was happening. So I started doing some research to explain it.
I found a company in China who makes Stainless Steel Spheres for art sculptures. The companies name is Shenzhen Maoping Sculpture Arts, they have been making stainless steel sphere for 23 years and can create any size stainless Steel sphere up to 20 feet in diameter, all crafted by hand.
it can take about 15 days for a 6 foot diameter sphere.
Based off my research, there seems to be 4 common ways to create a hollow metal sphere, Spinning, Mold Pressing, Water Pressure Hydroforming and Explosive Hydroforming.
This video shows explains what the compilation video was and shows the process of how to make a Stainless Steel Sphere using the Water Pressure Hydroforming method from start to finish.
Thanks for watching.
The 4 ways are = Spinning, Mould pressing, Water pressure Hydroforming and Explosive Hydroforming.
► SPINNING is like working on a lathe, they attach a flat round blank onto a machine, while the blank is spinning at high speed, they use various types of tools to start pressing down the blank into a hemisphere and then weld 2 hemispheres together creating a sphere. This method uses the skills of an artisan to create the hemisphere, and a lot of labour. But Larger companies will use a robot or CNC machine to do the hemisphere forming.
► MOLD PRESSING is just what it sounds like, they use a big hydraulic press and press a metal blank into mould and form the hemisphere that way, and then weld 2 hemispheres together.
► WATER PRESSURE HYDROFORMING is when you create a sphere using either flat or slighting curved pieces of metal into a large polygon sphere, and then using a hose and pump to send lots of water into the sphere under high pressure, forcing the sphere into shape. During this processes they can find any holes in the welds they created and seal them up.
► EXPLOSIVE HYDROFORMING is where you have a large polygon looking sphere made out of curved plates, the sphere is then filled with water and a small explosive charge, and when you set off the charge, the explosive force of the water forces the sphere into shape.

2:38 I imagine the caps at the top of the spheres when explosive hydroforming are probably designed to release at a pressure that's high enough to allow the forming to occur, but not high enough to destroy the sphere. Very interesting...

@loganhamilton9816 Жыл бұрын

Would they have to use a pressure valve? I feel like all that water and such a small outlet, the water should mostly block the hole allowing the explosive to still build pressure. Kind of like blowing water through a pool noodle, if there's enough water in the cavity then your cheeks just expand and you cant blow it out.

@JosephDalrymple Жыл бұрын

@@loganhamilton9816 You're not wrong. I suppose you could do either or... Either use a pressure valve, or make the hole small enough. I was actually describing a bit of both. You wouldn't even need to use a pressure valve per se, but instead make sure that the material, adhesive, and dimensions are enough so that the plug releases only after enough pressure has formed inside to form the sphere. I suppose that might be considered a pressure valve 😅 I'm ignorant on the subject, though!

@@loganhamilton9816 due supersonic shockwaves fluid dynamics valves and caps are not needed, the steel walls will get struck thousant of times reflecting shockwaves back to the center in the matter of a millisecond thats why it works soo good, the service holes are just to pour water and the explosive charge.

It's perfectly safe since water is not compressible and stores no energy in this state. If the sphere were filled with air, the compressibility would allow the storage of tremendous energy, making it a bomb.
