Soldering to Stainless Steel?????
Brian Snyder
The solder dosen't want to stick??? Is there a special type of flux that
I need to use or am I fighting a losing battle.
Any help would be greatly appreciated,

Try DUZALL flux from Esab group inc. Tel 800 638-1647
or http://www.esab.com/esabna.html
I have used it successors on stainless but iI just do not know what kind of
stainless it was. Try silver solder also.

If you are just trying to make a ground connection or
something like that then consider just drilling a hole
in the steel, installing a nut and bolt and solder tab
and lock washer through the hole, and then use the
solder tab as your connection.

I do it all the time. (Beer brewing a hobby)
You need silver solder with silver solder flux and more heat. the SS needs
to be very clean.
Good Luck,
Tom

flux in a core solder. You might try using a good acid paste flux. There are
fluxes specifically made for stainless steel. Are you soldering stainless to
stainless? It is important to get the temperature up high enough and if the
piece of steel you are soldering to is very large (as in even several square
inches) that can be difficult - often times a gas/oxy torch is needed (which
makes it pretty easy).

(like beer brewing) you would need it because you must use lead-free solder.
But for mechanical components lead-based solder works fine.

You can use regular acid core plumbing solder and a propane torch.
The thing is to get the steel just hot enough for the solder to flow
and adhere. If it gets too hot, the solder "unwets" and rolls right
off.
I've soldered stainless to stainless several times, and the right
temperature seems to be just above where the melted solder turns into
a paste. Once you have solder on the stainless, add more to make
whatever joint you're soldering- but make sure you're only melting the
surface of the solder you've already deposited. Too much heat, and
the whole pile melts and pours right off the joint. Wear long pants!
I used sandpaper to get the surface clean and rough, and plain old
plumbing flux. The key seemed to be getting the right temperature on
the stainless.

Nice one, Tom :)

T304 Stainless. Would it be better to use a mini spot welder????
Thanks a lot for all the great input!!

It might be easier to drill & tap a stud (if thick stainless), or use
a nut& bolt if thin- or solder a lug onto the stainless if a bolt is
impractable. Or, solder a screw onto the stainless, which receives a
lug & nut.
From the experience I had soldering to stainless, the process would
quickly destroy electronic parts.

If I needed a small solderable spot on stainless, I think I would apply
a dot of silver solder (with silver solder flux and a torch) and then
use regular tin-lead solder to attach the lead to that spot. To do
this, you may have to put some flux on a piece of wet-or-dry sandpaper,
and abrade the steel while it is covered with flux, before heating.
Spot welding might work if the transistor leads are a steel alloy
(common when transistors were in metal cans) but many transistor leads
are copper alloy punched frames, now. I think all transistor leads are
designed to be soldered.

If you're going to drill SS, you should use a carbide tipped drill. If
you don't, you're liable to burn up the drill. Stuff is TUFF!
There is a fluoride based flux that will allow you to solder to SS and
aluminum, but I forget what the name was.

While the solder and flux is important, the most important thing is to make
sure the surface of
the metal is -clean-. Use a fine emery cloth to rough it up well, then clean
it with a solvent such
as alcohol or acetone. Standard 63/37 eutectic solder will work with the
proper flux. I've even
had pretty good luck with Ersin and rosin core.
