One end of the tungsten rod is tapered by dipping it into molten ... may be required to get the wire to the proper size. It’s right in the name. TIG welding uses sintered tungsten electrodes ...

but unlike the MIG process that uses a continuous wire electrode, TIG uses an external filler rod combined with the tungsten electrode to complete the weld. This "hand dance" is what makes TIG ...

One functions as the targeting and communications platform while the other carries numerous tungsten rods–up to 20 feet in length and a foot in diameter–that it can drop on targets with less ...

So why weren't they adopted? Ironically, despite their simplicity, the "rods" would be prohibitively expensive. That's because tungsten is very heavy. NASA estimates that today, it costs around $ ...

But when you've got a tungsten cylinder and a ceramic cutter, you're in for an extra treat. The video starts out with some lovely sparks, but it's not until the end that the river of molten metal ...

Chance of this dog generating enough juice to power a lightbulb? Chhhhhh.... Nope. Science boffins: exactly how much heat energy do you think a 6ft tungsten wire can hold?
