I always thought this was impossible. Granted, he says it's not for importa
nt structural welds, but still, this opens up a new world to me. I'm pretty
so-so machining, and 12L14 just makes it so much easier to do passable wor
k. Also, I've been holding out for an affordable AC capable TIG rig to do a
luminum. If I can do this kind of welding on leaded steel, I'm a very happy
camper, and the TIG welder is coming sooner rather than later.
I stick welded 12L14 to steel once, just for the kicks, not for any
use at all, simply because I had scrap pieces of both.
The weld looked beautiful, like in your presented youtube video.
Then I hit it with a hammer, and everything fell apart instantly.
That is the biggest problem leaded machining steels.
A hairline crack can propagate in a microsecond.
309L is a pretty amazing filler for dissimilar metals, but you have to
be very careful about not getting it too hot or it will crack every
I could also say that TIG brazing is far better than TIG welding on
leaded steels. Silicon Bronze filler and half the amps used for
Since it does not melt the base metal, there would be much less chance

OK, that sounds like something I could live with. I'm not expecting to make
anything highly loaded, or anything where failure would present a serious
threat to safety. If I were to do that, I would for sure use properly rated
materials and methods (or more likely, job it out).
I'm comfortable with the idea of brazing. Is it really simply a matter of "
half the amps?" Would you then reduce the size of the electrode & filler ro
d to match the amperage? What flux would you use?
Sorry for the newbie questions, but I *am* pretty new to this.
