development channel

Good evening.
I may have packed myself, but I can't get a proper development of the channel in the image.
Should I close it with a welded wall?

in speed I would say:
or shorten the edges that overlap, if you made them with flange edge
or do a sheet extension, fill the excess with an extruded cut and then fill

so it is not developable. you have to change the joint of the two sides inside the curve....but you can never really do it...then one side will be welded or will be a fold of the other spondine.
so it makes no sense to be built.

Okay.
Thank you.
I saw right then, I wanted to be sure.
I will make a shorter fold with a rolled or riveted sheet.
Thank you all.
