Welding technologies for CFRTP`s offer the possibility for clean, high-strength, structural connections without weakening the initial fiber structure. Joining methods such as implant resistance welding are capable of producing a closed and fiber-fair structural connection of thermoplastic component parts. This paper deals with the implant resistance welding of carbon fiber-reinforced polyetherketoneketone (CF/PEKK). Welding elements were optimized as well as destructive and non-destructive investigations were made to improve the process performance of resistance welded specimen. The influences of different currents were investigated and welding strengths of 58 MPa were achieved.
