FSW head for NC machine tool

Stirweld’s FSW head uses a NC machine tool for FSW. This innovation reduces drastically the investment cost to access to FSW while offering performances identical to a special FSW machine.

Our products:

FSW head for NC machine tool: low investment cost, adaptability, ease of use and installation

FSW tools: low cost, higher quality, more efficient

Turnkey solution: parameters, jigs, training


  • Low investment cost: compared to FSW special machines or robotic stations
  • Adaptability: Despite the lack of standard machining centers, the StirWeld FSW head can be adapted to all MOCNs.
  • Ease of use and installation: After the first installation, the user can assemble and disassemble the FSW head in a few minutes from machining to welding and vice versa.

Head features:

  • Matching on 3 to 5 axis CNC machine
  • Assembly or disassembly in 15 mins
  • No hard or soft change of CNC machine
  • Force control to secure the weld quality from 1 to 18 kN
  • Water and air pressure cooling
  • From welding to machining without head disassembly
