It is an object of the present invention to effectively suppress the overflow of brazing material from each joint of a sinter-brazed component, such as a planetary carrier, obtained by brazing a plurality of members together. According to the present invention, there is provided a sinter-brazed component obtained by mating and joining a first member having a first bonding surface and a second member having a second bonding surface to each other. Brazing material is provided between the first bonding surface and the second bonding surface. The first bonding surface has a first recess, the first recess having an inner peripheral wall and a bottom surface. The inner peripheral wall extends along and on an inner side of a profile line of the first bonding surface.

A method of forming a weld interface between a first workpiece and a second workpiece includes arranging a reactive braze material at a first joining surface of the first workpiece. The reactive material is selected to react upon being heated to a temperature below the solidus temperature of the first and second workpieces to form a liquid-containing reaction product. Furthermore, an assembly is prepared of the first workpiece and the second workpiece with the first joining surface of the first workpiece and a second joining surface of the second workpiece separated by the reactive material. The second workpiece is then heated with a first laser beam following a first path and with a second laser beam following a second path.

A heating apparatus for induction heating is disclosed. The heating apparatus may comprise a bearing ring, at least one bearing element disposed in the bearing ring, and a braze material adjacent to the at least one bearing element and the bearing ring. The heating apparatus may additionally comprise an inductor positioned radially adjacent to at least a portion of the bearing ring. A current source may be electrically coupled to the inductor. A bearing orienting member may also abut a surface of the at least one bearing element. The bearing orienting member may orient a surface of the at least one bearing element. A heating method is also disclosed.

To provide a pipe drilling tool for forming, in a pipe, a hole for injecting a non-oxidizing gas such as nitrogen, when joining pipes such as refrigerant pipes by brazing, wherein the pipe drilling tool has a compact configuration allowing work thereof to be performed by the drilling tool being gripped by the hand of a user, does not readily generate burrs, and prevents cutting residue and burr residue from remaining in the pipe.

A joint member includes a joint main body configured to include a flow path portion formed and an opening portion communicating with the flow path portion, and a tube member configured to include an end portion inserted into the opening portion of the joint main body and joined to the joint main body by brazing. The joint main body includes a step portion on which the end portion of the tube member inserted into the opening portion abuts. The tube member includes an annular recessed portion recessed from an outer peripheral surface of the tube member and formed on a flexible tube side with respect to an end surface on a joint main body side.
