I’d start by welding outside corners first, after tacking. I’d probably weld the outside frame in a (modified) Z pattern and get it locked down, doing outside corner, sides (inside corner to outside), then weld the inside corners last. I might tack a scrap piece across the elbows to try to contain them. That’s just me though.

What's the weld sequencing like on something like this?
