Temperature measurement
Temperature is an essential parameter for the quality control of welding. You can now quality control your weldings at 100% while dividing by 5 your non destructive control tests. Discover our smart tool holder for temperature control the FSW welding.
Advantages of Stirweld Smart Tool Holder for temperature measurement
No battery for 24/7 availability
The tool holder is powered by the machine’s connections.
Use of numerical output
To avoid any signal perturbation.
Quality use for all
Installable on all existing FSW machines.
Temperature measurement offers you the best results in terms of repeatability.


StirWeld’s smart tool holder measures the temperature of the tool as the weld progresses.
This technology makes it possible to check that the temperature is constant during the Friction Stir Welding process, when measuring and recording the pin tool temperature.
As can be seen in the graph, although the tool rotational speed and traverse speed factors remain constant, the pin tool temperature increases significantly uponcontact with the weldsurface, when remaining almost constant throughout the entire FSW process.

Without this temperature control…
– Insufficient temperature would make it difficult to mix the parts, creating nugget
collapse or reducing mechanical properties.
– Too high temperature, approaching the melting point of aluminium, could lead to poor stirring or wormholes.
Sectors in which temperature measurement is key: aeronautics and space.
Temperature sensing system Features
– Accurate +/- 1 Deg C°, up to 600 Deg C°
– Continuous data transmission rate of 50 Hz


Our smart tool holders are available in fixed or retractable version:
SMART TOOL HOLDER FOR FIXED TOOLS
Interesting for it’s simplicity and cost.
SMART TOOL HOLDER FOR RETRACTABLE TOOLS
Useful for closing the keyhole at the end of the FSW weld.
