Areas of UP Application

The Ultrasonic Peening (UP) is the most efficient and economical improvement treatment as compared with traditional techniques such as grinding, TIG-dressing, heat treatment, hammer peening, shot peening and could be applied successfully for Different applications such as:

  • Increasing of the fatigue life of materials, parts & welded elements
  • Forming & straightening metal parts without inducing surface tensile stresses
  • Residual stress relieving
  • Increasing of the hardness of materials
  • Surface nanocrystallization etc.

The UP technology was applied successfully for fatigue life improvement of different parts and welded elements in a number of different areas/industries including:
