Friction stir welding

In friction stir welding, a rotating pin is pressed into the butt joint of two cooling profiles and moved along the joint line. The material is heated by friction and stirred by the rotation of the pin so that the materials join in a hot forming process. Since this process, unlike conventional welding methods, takes place at temperatures below the melting point, adverse structural changes are avoided when the melt solidifies.


Friction stir welding

Your advantages

  • No structural changes
  • Without additives and without great loss of strength
  • Very good and steady thermal conductivity
  • Very large designs possible (by joining several cooling profiles)
  • Joinability of different aluminum and magnesium alloys
