i am looking for some ss rods to do some stick welding with. can any one recommend a good rod to use on 316. Thanks for any help.
Reply:I use 308 and 309 rods for most of my stainless work, most of the citrus machinery we do is 316 stainlessLast edited by dabar39; 06-06-2008 at 10:53 AM.I am what I am, Deal with it!If necessity is the Mother of Invention, I must be the Father of Desperation!
Reply:I used the same, mostly 308, and we only used 316 pipe. Used it in waterflood applications and oilfield produce water can be really nasty. Never had a problem with the welds.
Reply:For welding 316-variant stainless steel, the right filler to use is a 316-variant filler.308 filler is NOT the right filler for welding molybdenum grade austentic stainless (316, 316L, 317, 317L, etc). 308 filler is the generally the appropriate filler to use when welding 302 and 304 stainless. But watch out if you are working with with the low-carbon 302/304 variants (302L and 304L), then the proper filler is a 308L filler. Some 308-class filler is multi-listed. I have some ESAB 308/308L I use so I don't have to worry about the carbon level in the filler.You can get a lot of this information yourself by getting a copy of the filler metal guide books from your LWS or by downloading them from the manufacturer/distributor websites. Like ESAB, or Lincoln, or Miller.www.esabna.com (ESAB North America)www.lincolnelectric.comwww.millerwelds.comAnd I'm sure there are many others as well.Lincoln lists BlueMax-316/316L AC/DC and RedBaron-316/316L-V MR and RedBaron-316/316L as applicable SMAW rods for welding 316 stainless. The RedBaron316/316L-V MR (3/32 and 1/8 dia, 8 lb cans) is listed as all position and specifically designed for vertical down use.The RedBaron-316/316L MR (3/32 dia in 8 lb cans, 1/8 and 5/32 and 3/16 dia in 10 lb cans) is listed as all position EXCEPT vertical down.The BlueMax (3/32 and 1/8 dia in 8 lb cans, 5/32 and 3/16 dia in 10 lb cans) are listed as all position EXCEPT vertical down. The BlueMax-316/316L is not intended for "joints in service in the urea manufacture industry"
Reply:309 will work for welding 316. It always seems alot less expensive as the 316.The problem with using it is that 316 stainless is widely used for its corrosion resistance properties and when you use 309 on it, you loose that property in the weld area.it runs similar to low hydrogen rods. I have found that the 3/16 rod is the easiest size to run in stainless.
Reply:i would be using it on my ss exhaust system on my car, i was wrong about it being 316. I called them up Friday and they told me it was SUS-304. Do they make a rod that would let me keep the corrosion resistance?
Reply:316 Electrode is best for 316 Material. JohnSMAW,GMAW,FCAW,GTAW,SAW,PAC/PAW/OFCand Shielding Gases. There all here. :
Reply:Lots of them.Stoody company is the KING of stainless wire and electrodes.
Reply:Weldgualt, I agree you should match the rod to the alloy if possible. When I first had to weld 316 SS 308 rod was all that was available. Leaving the system down for a week while waiting on the proper rod wasn't an option. I found the welds make this way were perfectly satisfactory. I was in a position to observe these welds for a number of years and they never gave a problem. They operated at 2500-2700 psi in some very corrosive conditions.

Reply:AWS Welding Handbook lists 308 or 308L as acceptable as well as 316.I r 2 a perfessional
