Thanks for an informative and well put together video. About 4 years ago I was quoting a similar type of job where 2 pieces of 1.5mm thick sheets were seam welded and a valve welded in on one of the edges. This was used as an expandable pillow that, in the flat, was slid into a sawn section of quarry rock. It was inflated under high pressure causing the cut to expand and separate the rock into a manageable size to handle. I'd love to see more of the shapes you have made👍

Please keep up your awesome work mate! I'm impressed how cool this technique is and how many things you can virtually do! Actually you inspired me a lot, I make furniture with wood and metal but I'm always been intrigued by stainless steel... I was just thinking these days what can I do (since I'm a novice tig welder too) and you have been the inspiration, that little spark that i needed. I thought that for the hydroforming procedure was required a much higher pressure, and apparently is easier then I thought... at least in terms of tools that are needed. I'm happy! Please, keep it up. 😊🤙🏼✌️

It’s hardly dangerous when you use water. That’s why pressure testing of vessels is done with liquids that cannot compress. If you pumped it up with air that is compressible,then it would be dangerous. Generally what happens is you get a tiny leak on the weld seam and you can no longer build pressure . It ends with a whimper ,no bang…

I was surprised by your statement suggesting those concerned about rust could use stainless. Have you tried this? I have messed around with DIY hydroforming, both pressure washer and grease gun techniques. I have never had a successful expansion in stainless, I have tried several different grades and thicknesses. I think it is because it work hardens so quickly. May I ask, what stainless have you tried? Did you find some trick to negate the work hardening?

We did a dome 3600 diameter 5mm steel, when the weld failed at about 250 PSI a jet of water blew out the wall of a nearby portacom office, smashed the windows and flipped the furniture inside upside down. There was no air, this was a result of the small amount of spring in the steel. If a person had been standing in front of it I think it would be worse than getting hit with a sledge hammer.

I have seen this process performed in a pool of water utilizing 1'2 in thick steel or titanium what they did to hydroform the metal into a half sphere is to suspend an explosive charge under the metal a precise distance. when they ignited the charge, it blasted the steel onto a half sphere. It was real quick, and the pool just about emptied out every blast. ''Explosive hydroforming" is what it was called. Metal needed to go into an annealing oven to take the stress out. Interesting.

Interesting. 58 years ago at school I put a waxed plaster of Paris mold with an aluminum sheet stuck to the wax in a 5 gallon bucket of water. Several inches away suspended a glass fuse with powdered explosive in it. Filming with a high speed 16mm camera( on loan),detonated the fuse. Five gallons of water vapor covered an entire football field for a fraction of a second. A flattened 5 gallon bucket landed a hundred yards away and a small aluminum ashtray was mostly formed. The science teacher determined although explosive forming with skock waves in water was interesting it was too dangerous to continue. This is the first time since that I've seen something similar.

Also,giving up on dangerous experiments and keeping as fit as possible has led to a long life.
