What Is Inertia Welding?

Are you looking to reduce production time and material cost? Don’t risk losing a competitive edge in the marketplace by overlooking inertia welding.

Categorized under friction welding, inertia welding joins metal parts together by force: a rotating component is pressed against a stationary component. This friction creates heat that allows the metals to flow and bond at the weld interface.

Benefits of Inertia Welding

How can you be sure that inertia welding will benefit your application? Below are some ways you can take advantage of inertia welding.

• 1. Combines a variety of metals

  This process is able to weld a variety of metals that can’t be joined through traditional welding. For example, your application may require (expensive) corrosion resistant materials. However, it might be unnecessary for your entire component to be resistant. Inertia welding allows you combine corrosion resistant materials with less resistant materials where there is no need. (Of course, inertia welding can also combine similar metals as well.)

• 2. Reduces need for expensive materials

  As a result of reducing the amount of expensive materials used, inertia welding can significantly lower cost without sacrificing quality.

• 3. Minimizes heat affected zones (HAZ)

  Inertia welding minimizes heat affected zones. In other words, material properties are less affected, leaving you with a cleaner finish that’s ready-to-go (thus, decreasing production time).

• 4. Creates strong, airtight bond

  Inertia welding joins materials together in a way that allows the full surface of the cross section to consist of both metals. The mechanical intermixing and solidification of the two metals is robust, airtight, and absent of voids and porosity.
