Abstract:
A method of joining a plurality of parts to form a unitary body comprising the steps of providing at least two sintered parts, each of the parts being formed of cemented carbide or cermet; assembling the at least two sintered parts into a shape of a unitary body, wherein each of the at least two parts has a joining surface and when each joining surface is brought into contact, the joined surfaces form a bonding interface therebetween; and subjecting the assembled at least two sintered parts to a vacuum or gas atmosphere, without the application of external pressure, and to a temperature sufficient to fuse the assembled at least two sintered parts together at the bonding interface to form the unitary body.
