2205 & 316L compatibility

[SAE140]

I'm about to start fabricating some 316L s/s fittings which will be living in a marine environment, using both 316L to 316L and 316L to mild steel welds, and have taken out a second mortgage (!) to buy the appropriate 316L electrodes.

Having done this, I've now been offered a couple of boxes of 2205 rods for silly money, and I'm now wondering if someone with s/s experience could advise me whether these materials are compatible, and whether I might run into any problems by saving money this way.

However, if I can use 2205 rods on 316 base metal using multi-pass, would you suggest finishing with a 316 cap weld, or vice versa ?

Thanks in advance.

What is a 2205 rod & who makes it?

[boilerman79]

They sound like some SPECIALTY maint.rod.read the package,it should tell you what they are used for.a lot of allpurpose maint.rods can be used with stainless.but find out what they are before you use them,or it may cause you some problems.Who makes them if it is eutectic,you can pull up their web site for rod onfo. most companys have a web site with all the info you need.

Look on the package and see if it has an AWS classification. That will tell you a lot in a hurry. Not all proprietary or specialty rods have or meet AWS specs.
