Treatment of metal structures to remove residual stresses
Technology implements
Highly effective reduction (by 50–70%) of residual stresses in welded and cast metal structures and structural strengthening of the welded joint metal.
The essence of technology
It consists in treating metal structures with repetitive pressure pulses generated by high-voltage electrical discharges in water.
Advantages of technology
- Environmental friendliness of the method combined with processing success
- Provides improved structurally sensitive characteristics of metal structures (long-term strength, durability, resistance to stress corrosion cracking)
- Productivity up to 2–6 t/h
- Energy consumption is an order of magnitude lower than with heat treatment
- The metal does not weaken
- The fatigue limit of welded joints increases with 30%
Technology efficiency
- Possibility of reducing residual stresses in welded structures and parts made of metals with different expansion coefficients
- Scale formation is eliminated; mechanical cleaning is not required, preventing metal losses
- Combined use with EG casting cleaning technology allows combining cleaning and stress relief operations in castings
Implementation
At enterprises in Ukraine and the CIS countries.
