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,
