Inertia Welding, also referred to as Rotary Friction Welding, creates a 100% bond of the contact area – such as a full-section weld around a diameter on the OD or ID of a tube – creating joints of forged quality. The weld properties are superior to welds created with fusion processes, such as MIG or TIG welding. This results in a higher strength bond and greatly increased design flexibility of part.
Inertia Welding is an environmentally friendly process that requires no consumables, flux, filler material, or shielding gases to run. Plus, there’s no weld splatter. It’s also energy efficient because it uses the least energy consumption of all welding processes.
Weld Cycle production times can be reduced, meaning that more parts can be joined in less time, since the inertia welding process is significantly faster than more conventional methods of welding. Many rotary friction welds are accomplished in mere seconds.
The machine-controlled inertia weld process is consistent and repetitive, eliminating human error while producing weld quality that is independent of an operator’s skill level. The process parameters are easily controlled, repeatable, and monitored, allowing for real-time and statistical monitoring of the parameters.
Metal combinations not normally considered compatible using conventional welding methods can be joined by inertia welding, such as aluminum to steel, copper to aluminum, titanium to copper, and nickel alloys to steel. This creates significant cost savings because engineers can design bimetallic parts that use expensive materials only where needed. Industries like automotive and aerospace will friction-weld dissimilar materials as a way of light weighting components for their applications.
