Steve Alderman took me to a local welding fabrication shop in Fort Pierce this afternoon and they can do the repair. Is there one alloy that's standard for aircraft exhaust systems? Can one of this group say with certainty what alloy is used in our exhaust systems? It's most important to use the correct welding rod.
