Abstract:

It studied that diamonds were encircle-melted by the thick metal alloy in the special methods, producing the diamond and tungsten carbide composite welding rod. Heap-welding tests indicated: the encircle-melted diamonds avoided high temperature burn loses, the good weld-ability, and the resisting wear of the diamond was used effectively.

Key words: Diamond, Encircle-melt, Heap-weld
