Friction stir welding

With friction stir welding a rotating pin is pushed in the butt joint of two cooling profiles and moved along the jointing line. The material is heated by friction and stirred by the rotation of the pin so that the materials bond in a hot forming process. As this process, in contrast to conventional welding procedures, happens at temperatures below melting point, negative jointing changes are prevented when the melting hardens.


Friction stir welding

Your advantages

  • No jointing changes
  • No additives and without large strength losses
  • Excessent and uniform thermal conductibility
  • Allows very large designs (by joining several cooling profiles)
  • Jointing of different aluminum and magnesium alloys possible
