1982 CB750F...Better Devil

No need to weld the whole seam. because the panel is so flat it likely will warp to shit and make dressing the weld more difficult. A couple solid tacks on each corner, and maybe one in the middle will do it. then grind those back and lay in some filler of your choice.
 
Thanks for the advice Doc. Everything I know about welding I learnt on a day course over a year ago, so I appreciate the pointers. After the epoxy fail I was planning on welding the intake scoop onto the panel from the inside to keep things clean, but I was going to run a bead down the whole seam. I'm going to can that idea after your suggestion, and try tack welding the corners and maybe one along the length.
 
What is your weld setup like?
Definitely don't do the whole thing. There is no need for it. Few tacks will be plenty. It's just to hold it together. Nothing structural, really.
 
I bought a 220V MIG gas welder on the cheap last year, but not really set up to use it. My mate next door has a 120V MIG set up (no gas) and but is learning how to use the thing. Between us hopefully we can bodge something together.
 
110 and 220 would be fine for what you're doing, but i'd definitely recommend getting a bottle of gas, instead of just flux core.

Flux core on 110 is always kind of crappy for us non professionals.
 
Man, that's it. I'm going to drop a few $$ on the kit I need (mask, gloves, few tools etc) and get busy with my 220v rig. My mate is amping to have at it with his 110v rig but, well, shit. His welding is pretty ghetto (which I admit is rich coming from me who's only done it once!) but I don't think I can be much worse. One sure way to find out.
 
May I suggest a good number of practice welds on the identical material before blowing holes in what you've worked so hard on so far?

I want to do something like this and learn how to weld.
 
Picked up a helmet, gloves and a bunch of misc parts and tools. Not entirely sure what my gas situation is like (poor, I think) but assuming there's some in the tank then I'm gonna get to welding on the morro. Weather's cheering up a bit too so the KLR's been clocking up some good miles. Shit it's good to be back in the saddle.
 
I've just discovered the next big thing in my life. Welding. Fucking love it.

Big shout out to @Hurco550, who helped me get from this -

Thanks man, really appreciate it. I know jack about this fine art but it's a ton of fun learning. Balls to the epoxy, this is for sure the way to go. I'll practice a bunch more before having a go at the side panels, but damn I feel like I've levelled up. The auto-darkening helmet is the business too, especially when it's on sale. And it has a skull and pinstripes on it, so you know it's the real deal :p
 
that's progress. You'll only need like 1/4 of one of the good beads or less in each corner then one mid way between, then fill the rest of the seam with epoxy so you don't warp em. That really is a lot of improvement from pic one to pic 2
 
That's the plan - after binning the epoxy route and teeing up the welding and getting some feedback here, I'll tack weld the corners and a couple spots in between. I whaled on a couple of tack welds yesterday, damn they're strong.

Ok so it's ugly as sin on the inside, but it's solid and from the outside it's clean. Bit like a girlfriend I once had Ba dum tss. Welded on a few captive nuts, bit more of a sand and these things are ready for paint -
