Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [ 1 ]
Rotary friction welding is widely implemented across the manufacturing sector and has been used for numerous applications, [17] [18] [19] including: Parts in gas turbine such as: turbine shafts, turbine discs, compressor drums, [20]
Founded in 1964 as Swanson Plating Company, and later known as CWS Company, it was not until under new ownership in 1999 that the company was renamed to Swanson Industries, Inc. The new ownership felt the name change was necessary after merging with companies Morgantown Machine & Hydraulics, Laser Processing Company and Morgantown Technical ...
Vibration welding has numerous advantages over other conventional plastic welding processes. Since the heat is created at an interface, the molten polymers are not exposed to open air, preventing oxidation and contamination of the weld during the process. No filler material is required, and when welding components of the same material the joint ...
In friction stir spot welding, individual spot welds are created by pressing a rotating tool with high force onto the top surface of two sheets that overlap each other in the lap joint. The frictional heat and the high pressure plastify the workpiece material, so that the tip of the pin plunges into the joint area between the two sheets and ...
Friction stud welding is a solid phase welding technique involving a stud or appurtenance being rotated at high speed while being forced against a substrate, generating heat by friction. The metal surfaces reach a temperature at which they flow plastically under pressure, surface impurities are expelled and a forged weld is formed.
