Hi all,

I'm after some advice as to the best way to achieve the best results welding up the part shown in the attached picture.

- The blue is mild steel rectangular section 40mm x 20mm x 2mm
- The green is mild steel plate 6mm thick

Would it be advisable to weld all the box section together in a rectangle first and then weld the plate on top?

Or better to weld each box section onto the plate, one by one?

I'm going to flatten it on a mill afterwards so doesn't have to be granite flat but the flatter the better really.
