    The last time I saw anything on Friction welding was about ten years ago at least. One of the aircraft manufacturers(boeing??) was putting it to use in the contruciton of 747's. They were smearing large sheets of aluminum together in order to make wing sheathing and fuselage sheathing. I thought it was pretty cool how they could join two sheets without using any heat.
    Will it weld? I loooove electricity!

    It's also used to weld the frame of the Ford GT 500. Why's depleted urainium so nasty?

    Good question. I think it's because of the word radioactive.
    Uranium is a naturally occuring substance. Outside of Golden Colorado are hillsides that show the marks of the old uranium mines that have been played out and (purposely) collapsed.

    The tailings are still there.

    DU is only 60% as 'radioactive' as those tailings. They don't call it 'depleted' for no treason. People hike and walk their dogs over uranium every day.

    U-238 (depleted uranium) is just fine to handle. It is dangerous in the sense that it is a heavy metal and is a TOXIC substance. If you had enough of it enter your blood stream or resperatory system then you might want to seek medical help ASAP! But other then that it's just metal. It has the same hazards as lead nothing more. U-235 however is unstable and highly radioactive. The reason U-238 is used for armor and armor peircing amunition is because it's heavier aand denser than lead.

    If you shoot a D/U tipped round it will catch fire as it leaves the barrel of your rifle or big gun or why. It will also explode on impact sending Uranium dust everywhere.. It IS dangerous no matter how you slice the pie. I'll have to go look for the link I found and post it here.
    Its a wild vid to watch...

    are you asking what makes the round glow as it is shot? on crew service weapons, like the .50 cal machine gun, there are tracer rounds that light up when traveling down range. these rounds are capped with phosphorous. usually it is every fifth round that is a tracer, so that the soldier can see where his aim is at night.
