    Default What's this coating that was underneath the paint of this welding table?

    Hey all,

    Beginner welder here, hacked together a table yesterday with a craiglist free coffee table and a couple garbage find pipes. It's not pretty, but better than hunching over.

    The coffee table top was painted black, and I ground off and sanded the surface to this copper-ish looking under coating. Underneath the coating is steel, you can see a few points where I ground past it in the photo.

    Just wondering what the coating is, maybe Cadmium? Copper? Any more details (why it's used, etc) are appreciated too.

    thx,

    oany

    could be copper plating if it is you are lucky in that they copper plate C clamp screws to help keep welding splatter from sticking

    Scrape a little off and burn it in an oxidizing flame. If it’s copper, it will be green, if it’s cadmium it will be bright blue.

    (Best to do it in a well ventilated environment)
