Question What is up with Silicon-Bronze MIG wire?

What is up with Silicon-Bronze MIG wire? Noticed this in this version of MM255 for Auto Body shops. What is the SiBr wire used for in auto body? It looks like they include THREE guns, one for steel, one for Al and one for SiBr...

Brazing via MIG.

My experience: It's nasty, splatters all over, hard to set up, our pieces were so thick (2 inches) they needed preheat. We were welding steel sleeves to a bronze cam for one of the mines down here, 10 pieces maybe once a year. Never could get a nice looking bead, but never had one come back either.

Never tried it on body work.

First off, I'm not a welder. I can weld, oxy, stick, and primary mig. I'm fairly good at brazing, oxy, good quality flux and rods.

I'm too interested in the mig brazing concept. I thought this was not possible due to how short circuit welding works.

OP great post - looking forward to learning more.

Thanks

Google "Spray transfer" for mig welding.

That is also what happens when you use flux core wire (gas or gasless)

Will I appreciate your responses, but I do not get what you're telling me.

The discussion is about brazing using mig. Yes, I can Google until the world ends. I had hoped, like the OP, to hear from others. Ya know, practical hands on knowledge.

I understand the mig flux core wire w/wo gas. I'm just curious to the ability to mig braze...

You asked how can it work when the only style of MIG (solid wire) welding that you know of, short circuits the wire.

I asked you to specifically google certain terms.

Did you doo this as of yet ?

What did you find ?

Search "MIG welding transfer modes"

I have no idea if spray transfer mode works with Silicon-Bronze MIG wire.
