First.. I am not an expert. However, I have had excellent results many times welding most metals to a stainless using 308-16 welding rod. This rod sucks the heat up the rod well and doesn't need much current to do the job.. lays well in most any direction.. sticks to the product well... builds quickly. Speaking of AC Arc welding. /←randy→/ The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.

Thanks Randy!! I have used Inconel 182 many time for Stainless to Crome alloy welds and I have had a very good sucess rate. That is what I am leaning towards I just wanted some other opinions.

The selection of the filler metal alloy for welding stainless steels is based on the composition of the particular alloy. Various stainless steel filler metal alloys are normally available as covered electrodes and as bare solid wires. Recently flux-cored electrode wires have been developed for welding stainless steels. Filler metal alloy for welding the various stainless steel base metals are: Cr-Ni-Mn (AISI No. 308); Cr-Ni-Austenitic (AISI No. 309, 310, 316, 317, 347); Cr-Martensitic (AISI No. 410, 430); Cr-Ferritic (AISI No. 410, 430, 309, 502). I don't knoiw about any others. It is possible to weld several different stainless base metals with the same filler metal alloy. I sure you want to match your filler material to you base metal. BTW, you can specifiy a filler-less weld. THis is normally done to prevent any kind of contaminants entering the weld. Have you talked with a welding engineer?

I don't know if the following are still active... AWS Filler metal specifications and related documents: A5.4 - Specification for SS electrodes for SMAC A5.9 - Spec. for SS Electrodes and rods You might look at MIL-DTL-13080E - ELECTRODES, WELDING, COVERED: AUSTENITIC STEEL (19-9 MODIFIED) FOR ARMOR APPLICATIONS Modified by Kelly_Bramble at Wed, Mar 01, 2006, 17:30:11
