Best filler rod for joining dissimilar steels...

I recall, vaguely, that there is a particular type of stainless steel
filler rod that can join all dissimilar ferrous metals, like tool
steel to stainless, tool steel to steel, steem to stainless, all
stainless, etc. I wanted to double check if my memory serves me right
and that it is type 312 stainless.

Thanks

The rule is that you want more chrome and nickel in the filler if you
are joining stainless to non stainless. There is a nice chart at
http://www.brazing.com/products/Weld_Stainless/selection_chart.asp It
shows that 312 is one of the choices for joining mild steel to any
stainless, but other good choices are 309 and 310.

I had the same question a while ago and Ernie recommended 309L for mild
steel to stainless by OA. Worked a treat!

What is your opinion about nickel rod, the kind you get when you clean the
flux off of a stick electrode.  That is what I use as kind of half way
between a tig compatible bronze and steel wire as for heat input.  I think
it is a good choice for dis similar metals.  If you buy out someone's stick
collection you generally get some of this kind of rod.  I guess some is just
high nickel not pure nickel the original intention I expect is/was cast
iron.

I am no expert, so hesitated to answer this. But my guess is that the
nickel rod would work well. The only drawback is that it might not
have the strength or hardness of a stainless rod. I am not very
familar with nickel.

If welding to cast iron - nickel will be about the only rod to use.

Has mat the flux
Has mat the bare rod (some people are allergic, but 'they' are testing for
cancer... therefore more charge.
