• …We can relief residual stresses without heat treatment
• …We can Stress relief at a 10% of the current cost
• …We can conduct on site stress relief of LARGE components
• …We can reduce stress relief time up to 95%
Picture a world where….

The equipment
• Accelerometer• Clamping• Exciter• Measurement and
exciter device.

The setup
The placement of the exciter will make a difference on the areas treated. So this process needs to be strategic.

– Prolong life time of molds
– Machining (process stability, quality, productivity)
– Before welding
– During welding
– After processing to prolong part life time
… and more…
Where to use VSR

- It has been used by more than 1000 Chinese companies
- It has been used in the US since early 2000
- It is used for US-navy parts
- …and Denmark has been the Nordic hub for this technology since September 2015!
It’s not a fairytale…
