Firebox weld joints?

Post by akjeff » July 6th, 2018, 9:26 pm

Getting ready to MIG weld up my firebox(1/4" plate), and was wondering what type of joint I should use, open or closed? If closed, do you bevel the edges, to get better penetration(and a flatter weld), or just but them up and weld away? Lastly, do you weld them inside and out, or just outside?

Thanks,

Jeff

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 welded both sides...lot of welding but the box hasn’t had any issues so guess it’s worth it.
