Title: Welder Q
Post by: Munch on March 29, 2009, 02:50:57 PM
I have tiny hole in my Leo Vince Exhaust system where it rubbed the swingarm undeneath. I'd say the hole is 1mm by 1mm, so its tiny.

Would a high temp silicone RTV plug it, JB Weld, or do I need it welded?

If welding is the only answer, what type of weld? Trying to figure out where I'd have to take it.

I think the system is a full Titanium system??

Thanks!

High temp silicone would work better than JB Weld. JB Weld is great stuff, but exhaust temps probably wouldn't be the best application.

Most systems are stainless with Ti cans. Not saying yours isn't Ti.

If you've solved the clearance issues I'd take the piece to a weldor that is good at TIG.

Actually I'd "assist" the clearance problem first with a small hammer to make sure it doesn't happen again.  Then go weld (or get a local welder) to fill the hold and polish out the weld to finish.  Super easy to do both and no more problems then.

if it were mine...

i would drill the rivets and pull the guts out, then us silicon and a little aluminum patch from the inside.  maybe a rivet through the hole to hold the plug better.

A welder with a stainless mig setup would take probably 5 seconds to fix it.  Same with a tig.  I think JB weld should be licensed and not sold to most people.  I've got some pretty good stories of fixing stuff that people have JB welded.  Up until about 5 years ago, I was a maintenance machinist, meaning I fixed broken stuff, some people should not be allowed to own big hammers or JB Weld.   Find a good welder.

  ;D ;D

Reading that made me pause for a rare moment of introspection.  But my weapon of choice for inappropriate repairs is Shoe Goo.  Some of your stories of JB Weld misuse would probably make a good thread if you find the time.
