for those who dont notice the stinger on the left. that would be a stick welder as the power supply. good idea. never thought about using one of those as an induction coil power supply. just 1 more reason to get a multiprocess welder. something with a generator if possible so it can eventually create its own fuel
well buddy... thanks for posting that video... i wouldn't have thought you would have been that successful with that setup... . next time... make sure your camera man knows how profound a thing it is to witness Tungsten being melted in someones home garage...and have him focus well with the camera.... lucky son of a gun go to be there with you n your girl... hope you are all very well. thanks again, very inspiring
Hi there, I think it was meant to be, but as far as I know, it is not enough for tungsten... Pure argon is always used while welding using tungsten electrode (TIG method) because tungsten is highly reactive and oxideses even in CO2 atmosphere (correct me, if I am wrong).
Wow! Congradulations on melting one of the most refractory materials of all time! I think I will use your basic design in my own arc furnace project I am working on. It seems to work quite well... almost too well. :)
You could have melted the metal faster if it were in the direct stream of electrons. If you used high density graphite rods and touched the metal with both apposing leads (graphite rods or gouging rods) and slowly pulled one back to create the arc through one side of the metal, it would have melted in a couple of minutes.
professionally they use an arc, not unlike this one, and they use a chamber filled with argon, just like you did, but they don't use ceramic, because ceramic just isn't tough enough for this job. instead they use a water cooled copper hearth. think, like, a copper cup, but the whole inside is super cold flowing water.
The crucible was graphite, the bricks were aluminum oxide based refractory. They melted into a beautiful greenish glass. They are rubbish now, for sure
what about magma/lava? :) it consists of different molten ceramics (e.g. oxides of various metals). Another molten ceramic could be aluminium oxide (Al2O3) in a furnace during Hall-Héroult process (check Wikipedia).
Well, you could melt about anything then. At those temperatures more traditional metals put in furnaces would boil and or vaporize. I am not surprised the brick melted, you said it was rated for 2000C (3632F), tungsten melts at 3422C (6192F). Tungsten melts at an incredible temperature, how in the world do they cast it? I would love to see molten liquid tungsten being poured, you wouldn't want to be anywhere nearby!
Interesting setup. Using the argon as a shield gas is a good idea. I would suggest that you tie down the tank so it can't fall over.
that was impressive that you melted the firebrick...

Nice setup. Using argon to provide an inert atmosphere is a neat idea. I hated the fact that half of the video is out of focus though :(

Not bad for a first try at welding ceramic bricks!

How is it an effort with an electric arc?

Verry Interesting carbon arc footage.
Who was screaming in the background a scared pedestrian perhaps?
By the way thank you for the shout out sir.
woow . . . . amazing, but very simple
I'll try melting glass this way.
thank you
Did it work?
@MrForestGreen Yeah I thought about the same exact thing, but I was thinking like Boron Carbide, it has to be 1700-2300*C..
Is it possible to replace graphite electrodes by something more easy to find ? Does it work with iron electrodes or charcoal pieces ?
nice vid, luvd it

So for your next process, why don't you make a mold from the graphite and melt tungsten into a usable shape?
So the bricks were obviously rubbish or not rated for the temperature seeing as the crucible survived
The crucible was graphite, the bricks were aluminum oxide based refractory. They melted into a beautiful greenish glass. They are rubbish now, for sure
why use gas ??
would an micro wave poweer suplie worck for this
doesn't this go way past the duty cycle of your welder? This does give me ideas though.

Induction heating or vacuum arc thats the only commericial ways of melting tungsten
Can I please come over to play at your house?
Cool until you realise it gets so hot nothing can contain it!
7:28 That looks like my T.P. after Dell Taco's Taco-Tuesday.
the power rails are under-rated, you should be using thicker wiring, cause I've saw them smoking a bit, and thats not normal.
how do you add the gas??
the argon/c02 is to prevent oxidation?
No it is to help cook the metal
insane
What the hell was that yelling at the end?
His hick wife!
P'se draw for me the circuit well labelled for study purposes.
