Burrs and flash occur
at the joint location,
affecting quality.
Probe wear is severe,
making tool costs a significant burden.
The appropriate tool and joining conditions
for new materials and new shapes
are unknown.
Efficient testing is not possible
because the joining mechanism has not been elucidated.
Due to many unknown factors, the number of parameters and tests increases.
I know improvement and investigation are necessary, but…
We don’t have enough time, staff, or equipment for testing…
We lack the equipment or know-how for evaluation…
We quantitatively measure and **visualize** tool wear, temperature of the probe tip and shoulder during joining, workpiece surface temperature, observation of defect status after joining, and spindle load, among others, to support the selection of optimal joining conditions.
Tool production
We can handle FSW tool production, leveraging our core technology in precision machining.
We also propose tool materials and shapes according to the joining material and application.
Tool material track record: SKD, Ni-base alloys, Cobalt alloys, Tungsten Carbide, etc.
Tool temperature
Real-time measurement of tool temperature and force during joining is possible using our proprietary product, MULTI INTELLIGENCE®i-stir!
Simultaneous measurement at three points can be utilized for heat input analysis.
Checking the joining quality
We can handle various light metal materials and confirm the quality of the joint surface after welding.
We are also actively researching dissimilar material joining.
Observation of defect state after joining
Defect status after joining can be confirmed using an X-ray inspection device!
By measuring the temperature during joining, the cause of defect occurrence can be investigated.
demonstration
Contract testing can be performed using Hitachi equipment.
Furthermore, experts knowledgeable in FSW are on staff, allowing for more efficient testing.
FSW testing after preheating the joining material with a high-temperature machine is possible.
*Up to 200°C
Preheating can eliminate the temperature difference between the joining metal and the base material, avoiding defects (cracks, distortion, etc.) caused by heat effects. This also allows for friction stir welding of castings, etc., where the above factors must be considered.
We will explain FSW (Friction Stir Welding),
focusing on our monitoring technology.
