Thermal management: liquid cold plates welded by FSW - Friction Stir Welding | Stirweld

The liquid cold plates are composed of a housing and a cover, to close the water channel. That is why it needs to be sealed, for which Friction Stir Welding is an ideal technique.
The advantages of FSW welding over other welding techniques are:
- Lower cost (Replacement of EBW or vacuum brazing)
- Higher resistance (up to 300 bar)
- Perfectly waterproof
- Excellent thermal conductivity
- Extremely user friendly, compared with EBW or vacuum brazing
In addition, with the Stirweld FSW head you will greatly reduce your investment cost as you will be able to weld directly from your CNC machine.
