Inflating Metal - Hydroforming Experiments Compilation

[@ConnorHolland]

Safety Note: The pressure required for inflating 1mm thick steel sheet is relatively low. As water cannot be compressed, the energy released from a rupture is roughly the same as using a regular pressure washer attachment. I always wear a face shield and stay at least 2m away during Hydroforming. When using compressed air for 'Aeroforming', I use very low pressure that is equivalent to a few strokes of a bicycle pump. I never use pressure high enough to rupture any pieces. I always revert back to Hydroforming if a piece needs more pressure to inflate fully, making sure there is no air left inside that can be compressed. I am aware of the potential risks, and always follow the necessary safety precautions.

[@madmax222]

Are you using the harbor freight electric pressure washer? It sounds just like mine l

@@madmax222 It's a Cotech, the cheapest one I could find

[@christilton350]

What if you sealed the water inside and then heated it

[@ConnorHolland]

@@christilton350 The steam would reach a higher pressure for more inflation, but with a very high risk of exploding. My methods are much safer

[@wastelandwanderer3883]

[@JarrenW83]

I beg to differ, expansion chambers for 2 stroke engines need to have good base material, have their joints fully welded with proper penetration and should not leak. It can be seen that almost all of the parts being "Hydroformed" must be pressurized to a point where it leaks, and having an exhaust with pores that leaks gas is not an exhaust.

Good welding seams!!!

[@DemonetizedVet]

If he would put more heat and flow more evenly across the work piece the HAZ would be even more parallel and he wouldn't have virtually any leaks at all. Another helpful tip before doing any forming retemp to about 150 or so and it will help the seams transfer better and cause less stress so even better chance they won't fracture. Metallurgy is amazing

[@JerenKanava]

@@DemonetizedVet Thanks, but what is HAZ

[@DemonetizedVet]

@@JerenKanava I'm not being rude or anything with today's society I just wanted that out there haha, So the HAZ is the Heat effected zone. If you mig or tig this is very easy to control due to the very small changes welders can make on the fly after a test run. Plus every "run or lot" or produced metel will react and behave different due to this factor so if extra scrap is around run it on there and check the HAZ and see how it spreads outward from the joints welded

[@christiannunez7964]

Hi Connor, great channel and videos, your work is truly one of a kind! I stumbled across your videos and channels as I was investigating sheetmetal fabrication techniques for a particular application (multi layer insulation). Basically, I need to hermetically enclose a short stack of thin metal sheets inside of a sealed sheet metal vessel, much like the weld sealed enclosures from your demonstrations. I have a few questions if you dont mind me: - have you used a thickness less or greater than 1mm? - what technique/type of welding is applied? - which alloy have you experienced the best (or easiest) welding success? - instead of pressurize with air or water, have you tried applying vacuum in any of your experiments (i.e. the sphere or football)? If so, to what negative pressure?

[@ConnorHolland]

Thank you for watching! I have inflated 0.15mm-2mm thick mild/stainless steel so far. TIG welding is the best option for control and ensuring no porosity. Mild steel or Stainless is the best to weld, Stainless is cleaner and mild steel is cheaper and easier to cut/grind. I haven't tried applying vacuum to any pieces yet, I'm not sure if hydroforming would create spheres that are stronger than spun or pressed ones, so data collected from those could be comparable
