SS Welding question

[Thedroid]

We're welding numerous pieces of 304L SS 3/8 together. We are using 308L-16 rod 1/8" to tack it, and I wanted to use the same but 5/32" to really stick it together. Turns out I can't get the 5/32" in time, but I do have 30lbs of 316L-16 3/16" that seems to be working good.

The environment is a very unfriendly place, and the 304 sheets usually last 2 to 3 yrs tops before they need replacement. I expect these welds to last 2-3 yrs at around 1200F in a high vibration, high abrasion environment.

Does any of you see any reason why the 316 rods won't work?

It will work fine. Always weld with a higher grade rod then the base metal you are welding. A 2-3 year life span is completely expected if prepped and welded properly.

It does seem to be ok, just a little runny. My main concern is the welds cracking.

insulate your welds after you finish so they cool slowly.. control your heat input to keep HAZ small... what are you fabricating?
