Characterization of the Polyetheretherketone Weldment Fabricated via Rotary Friction Welding
Polymers, 2023 Polyether ether ketone (PEEK) is frequently employed in biomedical engineering due to its biocompatibility. Traditionally, PEEK manufacturing methods involve injection molding, compression molding, additive manufacturing, or incremental sheet forming. Few studies have focused on rotational friction welding (RFW) with PEEK plastics.

Rotary Friction Welding of Dissimilar Materials
International Journal of Recent Technology and Engineering (IJRTE), 2019 Friction welding (FW) is a solid state welding method invented in 1940s by the welding institute. Without genuine liquefying of the materials, a normally excellent weld joint is produced with this procedure. The method is quick, environment friendly and easy to carry out.
