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 ]
A successful orbital weld is 100% automatic and repeatable as long as the operator monitors variables and performs periodic inspections of the weld seam for complete penetration of the weld. Noticing that a variable has changed during the welding process is a necessary skill for orbital welding technicians and operators that can be easily missed.
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 ...
Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. [ 1 ] [ 2 ] Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool.

Science try to gets good quality welds. There are many scientific articles describing the weld test, e.g. hardness, [2] [3] [4] tensile tests. [3] The weld structure can be examined by optical microscopy [3] [4] [5] and scanning electron microscopy.
