Hydroforming Cube with a Pressure Washer

How to use DIY Hydroforming to inflate steel cubes from flat to 3D. The first experiment attempts to mimic an expanding paper origami cube, but proved to be much trickier to achieve using sheet steel due to the large force required to unfold correctly. I may try this again, inspired by how the MythBusters managed to make an inflatable cube/balloon from sheets of lead.

It's more of a stress test for the welds.

4:46 - Most. Painful. Beach ball. Ever.

Wasn't planning on watching an awesome hydroforming video today, but here I am watching an awesome hydroforming video.

Being from the old school of oxy acetylene welding You might try that instead of tig welding . 2 U-shape bent parts to make the cube with 60 % less seams

Impressed with that hose and those fittings

Even if I know it would never work... I would have loved to see those first one's unfold into cubes. I wonder if that's even possible. Like, is there any kind of weld that can withstand that level of deformation?

[MajorDrinkins]

Great stress test. You can really improve the skill by doing this kind of work. Great training.

Hi, can i ask what gauge plate are you using here, and what method are you using to weld the edges together? ...Thank you for the fascinating content...

[JonMurray]

That cube was extremely satisfying. Awesome video as always mate.

I've been taught that you can't put a round peg in a square hole. Your video just blew the WATER out of that theory Hey wait! It sill doesn't?.... We kid because we love! Thank you for the video. The effect is memorizing. Cheers from So.CA.USA 2nd House On the Left

I made two stroke expansion chambers like that, but the welds take a real pounding.😊

[logancook]

would should try annealing the metal at different points in the forming

[Siberian]

Symbiosis of square and ball. I wonder which shape can withstand vacuum pressure? 👍

[SufiRepublic]

Nice video, could you please tell the pressure produced by the pump, and tge sheet metal thickness? We would be very thankful

Now paint it gold and put some question marks on it.

[jamespayne]

One would suppose that mechanical stress begins to affect the welds as the angles change during inflation.

[lexvelema]

Any tips on how to connect the hose? I welded the nozzle but the tube melted so i had to cut it of

[grahamjones]

It's like a steel LIPO failure without flame's 😂

Было бы интересно узнать как изменится прочность швов если сваривать лазером?

Too much boom means too much air.
This only properly works if you remove all the air.
Air compresses and water doesnt.
