welding differing stainless alloys together??

For years I thought 316L was the butter of stainless tig welding and was applicable to all stainless tigging.

Wrong! At least I think...

I have a few stainless sheet metal jobs, for commercial kitchens, and will be welding 304 18ga. sheet to 304 bar and 308 bar. What is the proper filler rod to use?

----------------------------------------------

308L is the most common filler rod for 304 ss.

a lot of folks swear by 308L high silicon saying it flows much better than plain 308L

thanks for the post,

jody
