4:38 Why cannot the type of heads be manufactured from a singe flat head or peace? Will it be weaker?

[@maxk4324]

I imagine at larger diameters (like the example shown) the amount of deformation needed to stamp/draw a hemispherical head from a single plate would either exceed the elongation-to-break of most materials, and even if it didn't just think of how large a press would have to be to both be powerful enough and have a deep enough stroke in order to perform the stamping. It likely just becomes cheaper and easier to do it in sections.

The limit of sheet metals width is the standard capacity width of the rolling mill. Anything requiring a wider sheet than standard is custom made or welded from the smaller sheet width.
