Inertia Friction Welding

Inertia Welding is a form of friction welding, in which parts are joined by pressing a rotating part against another component which is held stationary. The heat created by the friction allows the metals to flow, thus creating a very strong bond at the weld interface.

This process allows us to effectively and efficiently weld dissimilar metals that typically cannot be joined through traditional welding. This innovative process allows the use of expensive materials only where essential to significantly reduce cost while maintaining quality.

Pierce┬ácan weld parts up to 10″ in diameter and over 144″ long. Applications well suited for Inertia Welding include many types of rollers, such as those used in the printing and graphic industries, pistons, drill rods, and many other machine components. A variety of metals can be combined using Inertia welding. Pierce Industries Inertia Friction Welding processes are performed in accordance with the following standards: AWS C6.1; Recommended Practices for Friction Welding and MIL-STD-1252; Inertia Friction Welding Process, Procedure and Performance Qualification.

Advantages of Inertia Friction Welding

  • Allows both similar and dissimilar metals to be joined
  • Yields relatively small heat-affected zones so material properties are not affected
  • Friction Welding creates a robust bond with no additional weight
Inertia Friction Welding allows dissimilar metals to be joined, which reduces raw material cost.
By Inertia Friction Welding parts, we can replace the costly material with a less costly option while maintaining quality and adhering to all Customer specifications.
