How Tough is a Solid Block of Tungsten?!?!
Let's test a few different different calibers.

Thoriated tungsten is radioactive and will set off the monitors at my job.

It provides current to the welding arc. Most of the time you’ll add a filler rod like ER308 but you can just ‘wash’ over your bead if the need arises.
The tungsten is not consumed during the welding process as it is with stick welding. It also requires a shielding gas. Usually argon. |

It can also be alloyed with other metals or chemically altered (think tungsten carbide) to toughen the alloy. |

Tig isnt really nuke specific. its often the process used for welding stainless piping in pharma, chip manufacturing and other clean type facilities piping systems. even though the tungsten isnt technically a consumable, it does wear and get sharpened or replaced frequently by the welder.

Most of the clean room facilities are piped with small bore tubing and the welding is done with a process called orbital welding. Regardless, you still need certs to do this even though it's really an automated process. |

Tungsten Grinder. Most people just chuck it up in a drill bit and use a belt sander.

Some of those jobs, the minute I stepped on to them I was planning my exit strategy.
The worst from a safety standpoint was 3M. We were relocating Hydrofloric Acid tanks. Get that shit on you and it chews right down to your bone marrow. What a ****in’ nerve-wracking job that was. |

Over the years when i was with the tools, i worked in some of the nastiest places around. someone has to do it. you learn how to be safe, and also how to be prepared for those moments when stuff happens. I actually prefer working in those crazy places. usually but not always, it means better safety, better conditions, and the opportunity to make money. anyone can run 24 inch pipe across a mechanical room, but being able to do varied tasks often means you can make a home. its all in what makes you comfy. I preferred pharma and refineries over nukes, mainly because the nukes were such a pain in the balls to get in/out.

Tungsten is added to carbide to allow machining of different metals. Regular steel you could get away with just high speed steel but as soon as you get into different alloys, especially the exotic stainless steels, it would be next to impossible to machine it.

What the hell kind of protection gear do they even have against something like that?
