I either cut the plates a little short so that it's not a closed joint or I bevel the edges. I try to weld the FB inside and out because of the stress from the heat cycles but sometimes I'm lazy and i just weld the outside solid and all of the inside corners with a few stitch welds through out the inside.
Thanks for the feedback Big T. I already have the plates cut to size, so I guess I'll be beveling! Welding the inside sounds like a good idea, and will do that as well.
Yep, as BigT said. As you have cut them to size, bevel them and leave a small land. Good luck.

I know this is an older post but I recently ran into this. It's funny how you think you thought of everything in advance until you realize you didn't lol. I simply staggered my joints using the edge of the material. I was too lazy to grind the edges and the butt welds are gnarley to grind down. It saved time but it also means my box is now about a 1/2 inch wider than expected. No big deal in this case but definetly should have thought it through ahead of time. Great idea on stitching the inside too. I was kind of wondering if I should do anything with the inside.
When I build a 24” x 24” firebox and I’m using 1/4”
Plate. I just cut the plates at 23.5” x 23.5”. That way when I make each corner a 1/4” fillet weld the overall dimensions of the box will be 24” x 24”.
