Copper itself is a natural heatsink to begin with. I can't imagine why you would want to dissapate any more of the heat. I'm wondering if what you were told wasn't meant to hold the heat locally instead although I haven't heard of a heat sink compound being used this way.

Copper is normally difficult to weld simply because you lose your heat through the rest of the metal as it is quickly conducted away.
