- Just some initial hydroform testing with a pressure washer before i start to put it into practice and make something. Subscribe for more.

That shape of bulged out triangle is perfect. Make four of them, weld them as a tetrahaedron and try again. You will get a perfect sphere.
Buddy your sheets are flat. They have to be at least slightly curved. If you think about it using integral calculus just imagine your desired shape then square it out if that makes sense.
Example you wanted a puffed out triangle. Just add another layer of sheet steel starting off with a 3D object then smoothing out the sharp edges. So cut a triangle then cut a smaller one inside it. Then curve the smaller one slightly. Proceed to weld it to the larger triangle with the hole cut from it. Then hydroform it. It should work.
Love the Crocs mate :)
Angular 3d shape to smooth 3d shape.
Why use the robot narrator?
Did you model the shape you expected to get b4 forming? Wondering how far from the model the actual piece was.
U have to add more angels
Curious what that shape was supposed to turn into? I'm thinking if that pattern is something you really want to make maybe a thinner material would do better by not giving in one spot and holding strong and another causing that buckle. Just a thought im only a hobby metal worker. Keep trying bro ❤️
Your theory is sound but you need to go to the next step. Investigate “superplastic forming” with titanium.
Meanwhile, actual manufacturers are struggling to acquire steel.
are they?
Cry more
Seems like straight edges don’t do well. Try rounding all sides!
Why do you need a metal pelmen?
Move the position of the injection point to the middle and it should apply even pressure to stop the buckling.
The position of the injection point don't make a damn. He needs at least a somewhat 3D part to start with. Or thinner gauge steel. Expecting a 2D styled part to assume a 3D shape without distorting is a pretty tall order. Not impossible, but it'll take just the right shape to allow it. Look at those guys making the big tanks; lots of seam. Imagine making a shape as near as u can to what u want (with only 'flat' steel) then when u hit it with the psi, its got alot less forming to do. Thus less distortion

You have 2 curved edges and a 3rd being straight. As the curved sides bulge out it's putting stress on the straight edge that folds in like the second attempt. If you made it curved it should inflate like a samosa :)
looks like a muffler/2 stroke pipe
You need more than 3 sides and they need to be equal in size
You can’t just take to complete flat pieces and think it’s going to Hydro form. You have to attempt the curve a little bit multiple pieces at different angles.
Make a ball next it’s easier then shapes with edges
Measure the length of that leg before and after and then on your next one, make it that much longer
It needs to be all at once. Almost like a bead setter for tires. Have a chamber to store the psi you need then evacuate everything all at once.
wrong
@@picardcook7569wrong? So is that why the big boys hit it all at once? I assure u, they're using the most viable method
@oliverklozhoff7937 That's cute and all, but I don't take secondhand engineering advice from bitter internet children
@@picardcook7569 bitter internet children? Ok whatever. Perhaps a review of reading comprehension might help? I offered no advice, except the very strong likelihood that the leaders in the industry have determined the most effective technique off the muscle. Most likely the way these videos show it being done. But if you're the "maverick' type and like to fly in the face of the tried and true methods currently in use; by all means, knock your bad little self out! Better yet, go down there and show those engineers who knows what. I'm sure they'd be elated to see your knowledge on the subject come to life. I wouldn't mind seeing it either; but for different reasons (i love seeing a bufoon do his thing). But totally check into that comprehension thing! Maybe u could finally get promoted out of the dunk tank💦🤡💦
@@picardcook7569 but I'm curious; I didn't mention your mother, your glaring lack of common sense or your nasty attitude. So what about my original reply did u perceive as 2ndhand?
That could be great for making gas tanks
Not really because gas tanks (depending on which gas and how much pressure) have very thick walls so this trick wouldn’t work well on them
Needs firecrackers 🧨
water need to be in the middle
Go explosive and water right
Just explosives
Minimun edges should be >5
Change my indian mind.
why are all the boomers doing this i dont get it
Dude just get some ideas from some actual mylar balloons, everything puckers, but people have already done the math so why don't you Start to do your research there
