Thermal treatment and Stress Release


Small solid parts can be successfully stress-relieved in a very high intensity ultrasonic chambers. The following benefits of this technology are known:


  • Increase fatigue limits of metal, including welds by factor up to 2.5
  • Cracks are less likely
  • Artificial materials aging
  • Dynamic load bearing capacity is increased
  • Corrosion resistance can be increased
  • Residual stresses are released, very noticeable in welds
  • Increased weld strength enables overall material cost reductions in Structures. Use of high tensile strength steels and alloys with weld strength up to base material level become feasible
  • Operating and service life of constructions affected by dynamic loads and aggressive environments and mediums is increased
  • Stress relief effect maintains geometric accuracy during component manufacture and in operation
