This video highlights MTI’s Model 90B, a 69kN inertia friction welder. It’s designed to support the production of bi-metallic automotive engine valves. This model is built around the principles of inertia welding, a specialized type of rotary friction welding. It uses a controlled solid-state welding process to create strong, repeatable welds between selected bimetal materials.
The Friction Welding Process
For automotive applications, friction welding is valuable. It joins transition materials or dissimilar metal combinations, such as steel, stainless steel, or other advanced alloys used in engine valve production. Instead of melting the base materials, the inertia friction process uses stored rotational energy, pressure, and heat generated through friction to create a dependable welded joint.
The video demonstrates how MTI’s inertia friction welders are engineered for precision, consistency, and production readiness. As part of MTI’s broader lineup of friction welding technologies, the Model 90B provides manufacturers with a reliable means of producing inertia-welded automotive components where strength, material performance, and repeatability are critical.
