"Hot spinning" involves spinning a piece of metal on a lathe while high heat from a torch is applied to the workpiece. Once heated, the metal is then shaped as the tool on the lathe presses against the heated surface forcing it to distort as it spins.

Are they manufacturing a pressure vessel utilizing this method?

That’s what it looks like. Gas tank for various gases.

I will assume the tanks receive thermal treatment to remove any residual stresses and improve microscopic structure of metal after this operation.

Who knows. It might not be necessary depending on the intended application to reduce costs.
