A Study on Hydroforming

2022 - Present, work in progress| Steel

We spent a few days in the shop experimenting with hydroforming. where two or more pieces of flat metal are welded together at the edges, then inflated like a balloon. This process requires extremely high pressure and there is a high risk of catastrophic failure.

This process typically used in the manufacturing of motorcycle exhaust, some bicycles, and aerospace industry. In the shop, we've adapted this technique to metal sculpture, with many failures and many adjustments, we've been able to document behaviors of cold rolled steel when hydroforming, this will be usefull in the future.

Fitting adapter for high pressure pump


These two shapes were cut to the same size and shape, welded alike, and formed alike, the only difference is ~10psi pressure


After many attempts, we are beginning to see results


Failure = Education
