The welding temperature with the FSW head is managed according to 3 parameters:
- the feed speed: the faster the FSW tool feeds, the colder the material will be
- the rotation speed: the faster the tool rotates, the hotter the material will be
- Z-force (which refers to the force exerted vertically during the welding operation): the more the FSW head presses on the parts to be joined, the hotter the parts will be.
It is important to control these 3 parameters to ensure a good and strong FSW weld.
To get an indication of the temperature during your welding operations, you can use Stirweld’s temperature measurement system.
