Key Features of our Linear Friction Welding Machines

Below are some of the key features of our machines which makes them among the best in the world.

Energy efficient design
ETA has designed an optimized LFW process by a pre-heating stage to reduce the overall energy consumption for the process.
Forging of dissimilar Materials

LFW can be used to forge highly dissimilar materials like alloys of Aluminum and nickel.

Automation and Parameterization

ETA Technology has devised an automated and mathematical approach thereby ensuring that jobs are almost defect free and repeatable.

Complete Surface join

Full surface joining provides greater strength properties in critical areas.

Linear Friction Welding are widely used in Aerospace for manufacturing integrated bladed disks (blisks) for aero-engines. Linear Friction welding is seeing increasing adoption in other areas too, like Automobile, Medical Shipbuilding etc.

ETA follows a consultative engagement model with customers as we understand that each customer requirement provides unique challenges.
Such experiences makes us innovate and bring such technologies to mainstream.

Linear Friction Welding Machines

  • Max. forge force : 100kN
  • Max. linear rubbing frequency : 50Hz
  • Linear motion to slide : Through crank,driven by AC spindle motor
  • Amplitude : 3mm
  • Load control : By Servo hydraulics

Linear Friction Welding is a solid-state joining process similar to rotary friction welding.
