Abstract
A method of joining a member (A) which is difficult to fushion-weld made of, e.g., a hard alloy or ceramic, to another member (B) is described. The method includes the steps of: (1) fitting an insert ring made of a material fusion-weldable to the member (B) onto the member (A) by the application of pressure; (2) placing the member (A) with the insert ring fitted thereon in a predetermined position of the member (B) with a solder material interposed therebetween; (3) joining the insert ring to the member (B) by electron beam welding; and (4) melting the solder material by heating the member (B), thereby soldering the member (A) to the member (B). This method is applicable to, for example, the attachment of a tip made of a hard alloy or ceramic to a die of a pelletizer.
