METHOD FOR DIFFUSION BONDING NICKEL ALLOYS AND AUSTENITIC STAINLESS STEEL
The present invention discloses a method of diffusion bonding of nickel alloy and austenitic stainless steel materials. The method involves: heating a bonding interface of the materials by induction heating at a temperature range in an austenitic temperature region under controlled atmospheric pressure; applying a bonding pressure to maintain contact between materials during a bonding process of materials; cooling the bonded materials through specific time frames to ensure proper chemical interactions and minimize defects, and shielding a bonding environment using a controlled ambient atmosphere to reduce impurities, and prevent oxidation and corrosion. The method further involves forming and shaping subcomponents of stainless steel and nickel alloys.
Nickel-carbon and nickel-cobalt-carbon brazes and brazing processes for joining ceramics and metals and semiconductor processing and industrial equipment using same
A joining method includes placing a brazing element between an interface area of a first ceramic piece and an interface area of a second ceramic piece to create a joining pre-assembly and placing the components of said joining pre-assembly into a process chamber. Oxygen is removed from said process chamber and at least said brazing element of said joining pre-assembly is heated, thereby hermetically joining said first ceramic piece to said second ceramic piece. Said brazing element consists of Cobalt and Carbon.

Method and system for joining metal workpieces to provide a workpiece assembly
A method and a system of forming a workpiece assembly including an intermediate element between first and second workpieces. A ring element is included in or on the intermediate element. The ring element is for rotating the intermediate element about the intermediate elements axis. With heating elements positioned between the intermediate element and the first and second ends of the first and second workpieces, portions of the intermediate element and the first and second workpieces are heated to a predetermined hot working temperature, in an inert (non-oxidizing) atmosphere. While the heated portions are at the predetermined hot working temperature, and while the intermediate element is rotated about its axis, one or both of the first and second workpieces are moved axially, to engage the first and second ends with the intermediate element.

Automated portable friction welding system and method of operation
An automated system, method and tool for portable friction welding is disclosed for joining a rotatable workpiece to a substrate. A control system is disclosed receiving a start input to cause a motor to rapidly spin the workpiece and initiate a first thrust building cycle acting through an actuator to progressively force the spinning workpiece against the substrate. The materials at this intersection heat and plasticize and the actuator translates toward the substrate until the end of the desired actuator stroke operates to cut the motor off and to initiate and then hold a second axial thrust cycle on the actuator and there through to the interface of the workpiece and substrate. A reset input at the end of a cool off phase releases the thrust in the actuator.
