Tig Welding Brass

[@mattyl2297]

That crackling noise you hear is the brass burning, you shouldn't be doing that it brings out all the phosperity from the zinc. You end up with lots of little holes. Brass is joined melting the filler rod instead of trying to melt the metal. Try argon with a 2.4mm 2% tungsten @ 70amps DC. Much better

[@pixiepaws99]

So the goal is to stay in that super tight temperature range between the melting point of the brass and the boiling point of the zinc right? Melting the filler should melt it as soon as it reaches melting point and cool it off when it touches the base metal?

@@pixiepaws99 yeah you're basically brazing the material because brass doesn't fuse more sits on top but if you 'V' joining parts its quite strong even after grinding off to finish. I range from 70 to 100 on DC that's doing 1.5mm material to 5mm material I never go over 100 . I do it for a living. I been Tig welding for nearly 20 yrs.

@@mattyl2297 Thanks, that's quite helpful. What filler rod do you use? I use RBCuZn-C gas brazing rods for oxy acetylene brazing steel, but I haven't tried it with brass yet. I'll try to TIG braze with it using the technique you suggested.

@@pixiepaws99 filler rod C11 Aws/SFA 5.7 it's more copper than brass . I use 1.6 and 2.4mm rods. With Argon gas. It's all down to practice and confidence. Brass is by far the hardest I've ever had to weld. It's getting the right temp and speed without getting the phosperity. Good luck

Thanks man today I will try again cause I need a "glue" on some cas iron parts, just to stay in place. But epoxi was not enough and nickel is way too expensive and hard.

This is great demonstration of what NOT to do

[@juanignaciocaino]

too much heat input and you need your filler to have some cadmium. Look into smith's filler wires that have different melt/liquidous points and try them with the TIG and you'll get better results. Also use a thinner electrode.

용접봉은 어떤거 써야되나요?

Hi mr Lee I m tig steel welding wark bat not brass welding is wark plz help me

[@scottdeaussie]

What filler rod is this?

[@Mrleewelder]

Copper alloy tobin bronze 2.4mm

[@stefaniedmms]

Which filler wire is the vest for tig brass ?

[@Mrleewelder]

Copper alloy tobin bronze 2.4mm

[@carloscastaneda8302]

I use Silicon bronze

[@quartfeira]

L-Cu 40Zn

[@qwkkwp]

CuSi3

[@shebelehaggai2754]

What is the tungsten colour code and is it burning on ac or DC out put?

[@Mrleewelder]

Hi mate White and dc

[@rcbikesfabricacion3090]

brass is an alloy not a pure material all alloys should be welded with ac

[@jacobjames1171]

My chest hurts just watching.

[@Mengkomnap]

Nice

[@ThatOneOddGuy]

Well I guess it's time I get a TIG welder

[@JarekGmrcy]

VERY GOOD!!!

[@marlonckmayblog880]

Argon gass sir

[@rcbikesfabricacion3090]

damn how can so many people be wrong about welding brass you need ac not dc you should take vid down you not doing it right and showing people the wrong way to do it

[@gintautasa8135]

Wrong wire feeding. Been welding brass for a while, and in my company we do different, better way

[@Mrleewelder]

Thanks for the recommend reply Many company use different methods

[@skarandysovsky7575]

Can you show us ? Would love to see video

[@zuhalfast3388]

Define ‘different and better way’

[@Andrew-rk9il]

Looks fine to me it’s came out nice doesn’t really matter how you do it as long as the results the same
