Welding Tips and Tricks

trying to learn about tig-ing 409 ss for a exhaust project.....looked through a lot of videos...looks like I have my work cut out for me...I appreciate the info out here...

slacker,
Welcome to the forum.

If you're using 409 in an exhaust you'll need to use ER430 filler and you can also butt weld it without filler if fit up is good. If it's going to tie into any Carbon steel components it will need to be welded with ER309 filler. You'll be better off i you pre-heat it to about 300* F. You'll also get better results if you purge it with Argon, but not 100% required.

slacker1965,
Welcome to the forum! There are several of us that do exhaust work and can help in many ways, others are better suited to help that me though. Post up some pics of what you will be working on when you get the chance.
