    Cool

    Its called cladding like the nickle and copper in coins. It is done underground outside Pittsburg with explosives. The force of the blast seals the different metals together....Bob

I'm going to go out on a limb and say theat the strength of this join was very high as it is used on load bearing transport trailers on public roads.
    I know what your talking about, I was also shown this on a drop deck trailer, didn't believe it until I saw it! I also was shown a coupon of 18ga cold rolled welded to a similar thickness aluminum coupon using a Fronius machine. It's cool to see constant devolopment in this great trade!

    A few months ago while I was healing from surgery I watched a show about this process( Explosion ** welding on the discovery channel, you may be able to contact them and buy the episode and as I remember the process was very successful.

    Hope this helps

    Here is a link from the Fronius website that explains CMT. Looks like a pretty cool process!

    Default here's a piece

    JM,
    Heres a piece of "cladding" as Bob calls it. I have had this piece since i was 12 years old. My grandfather brought it home from a ship yard. It is used to join the steel hull (where strength is needed) to the superstructure (where light wieght is prefered).

    The process as to how its made, i havent the foggiest. So Ill go with Kaboom!!! It sound exciting enough though not the educated answer I would rather have given.

    Enjoy.

    Default Oh boy here we go..

    Melting steel and fabricating things that were useful was the reason I believe I went into welding. The electrical arc and watching steel melt before my eyes was as good as se%! Now imagine blowing crap up! Oh man, someone please approve this process now.

    I saw that. It has been observed for some time and noted in the military where examples of unlike metal to metal welding takes places in combat situations. Tanks getting hit with with extreme high speed rounds that cause the inside metal to melt and explode in a process called spalling. It was noticed that in testing that welding was taking place. This led to:

    They take to plates that want welded together, lay one atop the other and cover it in plastic explosives. Not sure what kind, but it has to be high speed like det-cord.

    In spite of it sounding crude it is far from it. It is a very precise process. Too much C4 and the metal no longer is with us, too little and nothing happens.

    here is some more info:
