sheet metal flatten a cone/dome

Morning,

Attached are two models I've started.  The final design calls for 6, pie shaped pieces to form a shallow dome with a tapered edge.  I wanted to make this out of two pieces, is there a way to covert these pieces to a flat patter so I can add cut-outs to all faces?  Then I want to weld them together to complete the final assy.

Thank you,


Steve
