Why not use 316L SS wire as filler ?

Interesting stuff.
Might be worth trying

Thanks for the feedback. If I learn to tig braze-weld and ever try
the braze 655, I'll post the results here. If I decide to learn tig
welding and braze-welding, it'll long after the summer is over. Good
wishes to all!

Why not use 316L SS wire as filler ?

Martin

If you do a google group search on tig braze-welding, you'll find the
details. TIG-Braze Welding - Chapter 3 would be a good thing to
search for (sci.engr.joining.welding newsgroup), but there are a lot
of messages about tig braze-welding.

Using 316L ss wire as filler would be regular welding, and the base
metal would melt or be distorted.

Using the silicon bronze, which has a lower liquidus point, the base
316L ss would not be melted or heat distorted very much, depending on
the amount of heat applied. The result would be a "braze weld" or
whatever you want to call it - I don't want to get in semantics
argument.

316L physical properties:
Physical Data

Electrical Resistivity (microhm-cm (at 68 Deg F)) 444

Melting Point (Deg F) 2550

Modulus of Elasticity Tension 28

For what I plan to do, considering my non-skill level, brazing with
oxy-acet and the Meco torch and the appropriate filler is a probaly
the way for me to go, from what I've learned from the folks in this
newsgroup. But, tig has been mentioned as a good alternative
and....so I've been reading.

Oh! I just remembered something I did a while ago. I needed to stick a
bunch of nickels (25% Ni, 75% Cu) together, with a similar metal. Not
brass. So I grabbed a length of copper wire and some gouging rods (for
carbon arc) and non-TIG-braze-welded them together. G Doesn't work that
bad, just needs some control over oxidation.
