Fun fact, I'm a journeyman Welder 14 years. We use tungsten electrodes for T.I.G (Tungsten Inert Gas) welding. The tungsten electrode makes short contact with the metal to be welded, current then flows from the tungsten electrode to the metal to be welded, and filler material is hand dipped into the molten puddle, created by the electrical current. The Tungsten electrode is held by a special hand torch which also supplies an inert gas (argon) to protect the weld from our atmosphere. The tungsten electrode does not melt from the current, unlike stick (SMAW) welding. The polarity (way which the current flows) is opposite to other welding processes to prevent heat from melting the tungsten. If you have the polarity wrong, the tungsten electrode basically vaporizes 🤣

[@kokeskokeskokes]

Or just set the balance way down on AC and the tungsten will melt very quickly with 200 amps or so. I imagine 350 amp TIG machines would melt a thin tungsten electrode in less than a second with the balance low.

[@danajohnson5993]

In tig welding of aluminum, we used reverse polarity with the electrons going from the work to the tungsten electrode melting it into a shiny ball. The positive argon ions moving from the electrode to the aluminum blasted away the aluminum oxide film on the aluminum work piece and allowed it to flow together with the welding rod. High current was required to melt the aluminum quickly at the weld before the heat spread to the rest oh the workpiece causing the whole thing to melt due to its high conductivity and low melting point. The tig unit had a timer that kept the argon flowing after the arc was turned off until the tungsten cooled below its oxidization point.

When doing some semi-related research on ceramics for extreme heat resistant applications last year, I came across an article detailing the manufacture of Hafnium Carbide. The lab doing their due diligence didn't have a torch hot enough to actually melt their sample and resorted to lasers (!!) to get the job done. If memory serves, the melting point was eventually found to be at or slightly above 4K Celsius. Not sure it'd be too easy to obtain a sample, but I suspect it's out there somewhere. The proposed use of this metal was being tested for heat shields on spacecraft and in-atmosphere hypersonic aircraft panels.

[@Jtretta]

Hafnium is actually very useful in nuclear power. The combination of it's absorption cross section, chemical/mechanical properties and 6 stable isotopes make it an excellent material to make control rods out of. You can actually use them in a couple cores, as they remain "neutron black" over extended exposure to operating conditions.
