Technical Tig brazing

Is “Easy Grind” mig wire silicon bronze? I remember that a few years back this stuff was recommended quite often.

 

Nope. That was a steel alloy, and appears to no longer be on the market.

 

Tighter fitting, cleaner joints result in less grinding.
That’s my ez grinding solution

 

ESAB seems to list it still

And it has been a long time since I bought wire, just looked at the prices!

 

I do header flanges the same way as Marty...TIG weld the inside and silicon bronze on the outside. It helps prevent burning through the pipe when welding to a 3/8" thick flange...which leads to cracking down the road. I also use it a lot for bungs and lap joints in steel to keep distortion down.

 

There is not a dang thing wrong with using silicon bronze. It is used day in and day out in todays custom car industry.
As long as you do not use it structurally for the most part. the only people who hate on it are those that have never used it. i wouldn't want to make a camo panel out of it for fixing rust . but dont be afraid to put it in small voids or whatever

 

Still readily available here in the PNW. Just bought a spool from my Buddy that owns a welding and industrial supply store.

 

Weird. All of my locals look at me like I have three heads when I ask about it.

 

Very interesting. Do you need a really thin bronze rod to tig sheet, like when you use a steel filler rod? (I've often used .8 mig wire) I've got some chunky rods at work (inherited) about 3 to 4 mm diameter, I think I need to play. If Id known, I could have saved my self loads of aggro with distortion.

 

It does melt at a much lower temperature than a steel alloy. That said a thicker rod will require more heat to melt it. Still and that will be a whole lot less than what it takes to melt steel.

And your case it's probably going to take some experimentation to determine just how much heat, and the exact technique for getting it to flow out the way that you wanted to given the size of the rod.

Anytime you use a rod that thick you're definitely going to have to grind off more filler material in order to get it smooth, and that just brings in more heat to the situation.

Heat on thin metal, as we know, is the enemy.

 

I'm going to post my build under traditional custom tonight, I think that's the place it belongs its a 24 model t door are welded trunks cut off ect. You will see the horrible body work don't by previous owners and holes i will be filling with silicon bronze

 

I can get product info for you if you would like.
