Exhaust Welding
zilspeed - 24/12/08 at 02:12 PM
Now that I've finally finished the engine mounts, I thought I would have a wee go at the exhaust before closing up the garage for a couple of
days for Christmas.
I really am in the early days of ability when it comes to welding, so it really was a case of suck it and see.
Using the Mig on minimum power with the straight CO2 I figured I might as well give it a go.
Now, please bear in mind that I have dressed this weld, but that doesn't matter a jot to me. As long as it's sound.
Really pleased with the way it turned out and am looking forward to getting a day in again and getting the job done.
This has been one of those jobs which has been hanging over me for months now - it's so pleasing to see that it just works. Seeing as I'm on
a budget as tight as a coat of p0aint, this is major good news. Probably quite trivial to someone that knows how to do this kind of stuff, but not
me.
Wee pic. One unifinished stub still with the slots in it from when I thought that sleeving the exhaust might be the way to go. Next to that, the
welded section, dressed ready for coating.

Ive been loking at my exhast, seams to be a pin hole on one of the 4-2 joints showing through on the exhast wrap. Hesitent to have a go myself as it
might just get worse. But your work looks good to me only way to test it is to put it into service.

Cheers James, you can have a good close look next time you see it up close.

Yes, the top one has been welded and that is exactly the look I was going for, one piece which has been sanded.
Dhutch try this video for how to fill a hole

I made the fit as good as possible and where it had a slightly wider fit (like 1mm gap compared to 0.1mm at the good bits) I worked the weld across
from side to side along the front edge of the weld pool until I got back to the good fit again.
Believe this if you will, but it was watching programmes like American Chopper where all of their exhausts are cut and weld followed by polish that
convinced me I could go down this route.
Still to come, Zils guide to cutting a pre formed bend to maintain a constant radius and how to choose where to cut.
Oh, and have a Cool Yule everyone
