    Michael, I've taught myself to weld sizings. Whether or not you
    get porosity in the joint seems to be in how fast you can
    recognise that the joint has fused. That is, it's all in the heat
    of your flame. Too oxidizing (too hot) and you boil the metal and
    pump Oxygen into the joint. Too reducing and you take too long to
    fuse increasing fire scale and maybe heating too large an area
    and slumping the weld. United's #57 Sterling also works with this
    technique. Try it, You'll like it. ( After a little practice)
