    It looks like this metal is used for Body Piercing. The two alloys
    that were mentioned in the article are iron and nickel. Both should
    be weldable. The first problem is the amount of the argon gas the
    customer uses. 

    1. He should use 7-10 cubic feet per minute out of the central
    nozzle. He should not use the side nozzles. It is evident that this
    user was not trained on the laser.  

    2. The parameters are much too high.  I have never welded this
    material before but I suspect it should have similar parameters to
    stainless steel: 250 volts 2.5 - 3.0ms 10 beam diameter. (1/2mm
    spot).
