No flex paste?
I’ll give that a shot!!You feed it into the weld puddle.
Another one is to fill a gap,lay it in and weld away. You have to control the rod, like brazing with oxy/acetelyne.

First, try to avoid welding on the rusted sections.I’ll give that a shot!!
Metal is clean but there are places where things get thin due to rust.First, try to avoid welding on the rusted sections.
I think thats what Franks was explaining. Try setting and running it as Frank suggested on some good metal.
Come back and fill for when there are holes.
Been there. it does make it tougherMetal is clean but there are places where things get thin due to rust.
Brand new metal, it welds perfect. Like I’d put those welds up for a cert test. It’s the old metal on the thing that’s a challenge. I try to clean both sides but some areas I just can’t get too. Another example of why I wish I’d just ponied up and chem dipped this sob.Been there. it does make it tougher
Chem dip would make it a challenge anyway. And likely find you a lot more work. Also, and this is huge,find a copper block. Use it for backing. Anywhere its thin. Thank me later.Brand new metal, it welds perfect. Like I’d put those welds up for a cert test. It’s the old metal on the thing that’s a challenge.

Sometimes I use silicone bronze wire for Tig if the metal is super crappy and thin.You feed it into the weld puddle.

I cannot stress enough read the part above about the copper plate for backing. I use some old salvaged bus bar. Note to self, it stays hot for a long time! Hah! Ask me how I know!Chem dip would make it a challenge anyway. And likely find you a lot more work. Also, and this is huge,find a copper block. Use it for backing. Anywhere its thin. Thank me later.
I've brazed with moderate success when its thin (Oxy-Acet)Sometimes I use silicone bronze wire for Tig if the metal is super crappy and thin.
Steel wont stick to the copper block. I have to buff it from time to time.I've brazed with moderate success when its thin (Oxy-Acet)
I've always assumed the copper block will not help with a torch. That it would just get burned and/or contaminate. True?
And can get it for the mig welder too. I have yet to try it.Sometimes I use silicone bronze wire for Tig if the metal is super crappy and thin.
If I am brazing with a torch a lot of times I use the heat sink paste vs the copper backing plate. Honestly I have found I can Tig thin stuff with less heat distortion than I can with oxy torch.I've brazed with moderate success when its thin (Oxy-Acet)

Try it Frank it has a much broader application range for alloys. Basically if it is metal it will stick! Hah! Works great on anything contaminated. “It will buff out”And can get it for the mig welder too. I have yet to try it.
I’ve been using a sheet of scrap copper and a pair of vice grips to hold it where I can. It’s the areas I can’t get behind that’s I’m struggling withChem dip would make it a challenge anyway.

When youre talking Si-Bronze your joining it like a weld right? As opposed to capilary action like soldering (which IIRC) is true brazing?Try it Frank it has a much broader application range for alloys. Basically if it is metal it will stick! Hah!

Hmmm is this special order or would any welding store have it?And can get it for the mig welder too. I have yet to try it.
CorrectWhen youre talking Si-Bronze your joining it like a weld right? As opposed to capilary action like soldering (which IIRC) is true brazing?
SI bronze is typically at any welding supply house most carry it in both 1/16 and 1/8 I typically just use the 1/16. Use it exactly as you would regular tig rod. It’s melting point is super low..Hmmm is this special order or would any welding store have it?
