Can u Weld Ceramic Coated items?
I have a 1.5 inch merged header & hideaway exhaust that I was going to have Ceramic coated, but I have it all welded up as 1 item as it returns as
a centre mounted outlet like the Porsche Boxter & I find it easier to take on & off this way. I was told that I couldn't have the exhaust
coated the same way inside & out as the header as the baffles wouldn't take it. So I thought that I could just cut the muffler off , have it
done seperately, (outside only) then weld it back on after. It was mentioned by a friend that u couldn't weld something that has been Ceramic
coated. Is this correct?
regards
Jak

you will get more informed welding advice than I,
but I believe that if you just grind back ceramic for the weld then no worries.
-
Could you weld Flange joint on so bolt together later?
-
Could you overlap the pipes so that just a few small stitches are required to secure later.?

When I had my exhaust coated I was assured it could be welded afterwards. Never tied it though.

From what I understood, the ceramic coating actually improved the weldability.
Best to check with whoever is going to coat it, as I am sure not all coatings would be the same. I have welded a ceramic coated muffler to an uncoated
exhaust pipe before, and didn't have a problem.

Hi
My cermamic coated system has had a few leaks at the flanges and I welded them up no worries, it just destroys the coating in that area.

For a better welding job i suggest that you grind the coating off in the weld area first....
The ceramic coating will act like a slag and probally flow into the weld filler material and give a slag inclusion.
This will weaken the weld,
