How would you weld this[/IMG]

How would you guys weld the long join on this panel I would normally mig it to keep the distortion down but wondered if gas welding would be ok or would it be to hard to control

Is that a butt weld or an overlap seam?

Babygee 10-21-2018 08:15 AM

Itís a joint

I generally TIG weld the long-side sections on Buses. I can tell you from experience that the repair you are doing is one of the most difficult to do correctly.

I always remove the floor as it usually needs replacement and it's the only way to access the back of the weld. Also, it's a good idea to planish as you go. That big, flat panel doesn't take heat well. I tack it up. Do a light planish then weld and dress as I go.

Here is the latest one I've done on my personal project. Not a split, but a similar process:

Cool Mango, semaphore Bus, by the way...

Itís not mine itís a mates I welded this one up a few years back the whole side was a mess but was on a tight budget so we just did what we had to I ended up tigging it it turned out ok but would like to get it a bit better
Itís actually the yellow bus in the back found Iíve got to do now

Take pictures. For me, T3 from 1981 is waiting in line.

All the legends on this site seem to prefer oxy welding.

Good luck!

long welds on flat panels

If I tiggyed it, I would use the .040 tung, #3 cup and 40-60A.
If I torched it, I would use a #0 tip,

Tack and planish full length, either method, until tacks are 1.5-2in o/c.
Then start at one end and weld 3in, and then hot planish - with a rigid straight edge on the panel every minute. Repeat until done.

Hint: I do not let the panel get ahead of me.

THIS IS NOT A LONG WELD. (Steel panel for an old XKE.)

I've had to weld a lot of flat panels, and have gone to file finished in most cases...

Sedans, coupes, vans, panel trucks - sides, roofs, hoods, floors, firewalls. Steel and aluminum.
This is what works for me, and is a variation on the different styles/procedures I have learned from the senior metal men, over the years.
Methods are generally the same - how you combine them is your style.

(p.s. - I have long arms w/6.5ft total, fingertip to fingertip):)
I'm not much good working inside trunks and engine compartments, though. :rolleyes:

Itís how I would have done apart from would have probably tried to run the weld in one go after tacking but I think your approach might keep it in check a bit more
