Ultrasonic Impact Treatment Solutions (UITS)

Improving and Rehabilitation Technique for The Ferro-Magnetic Material Utilizing Ultrasonic Impact Treatment Solutions

Stress concentration and residual stress is the main reason to cause fatigue failure and damage. Residual stresses are stresses that remain in a solid material after the original cause of the stresses has been removed. It is divided into two different types of residual stresses which is known as desirable and undesirable residual stresses. For welded joint, residual stresses primarily develop due to differential weld thermal cycle (heating, peak temperature and cooling at the any moment during welding) experienced by the weld metal and region closed to fusion boundary i.e. heat affected zone. Presence of undesirable residual stresses in the weld joints can encourage or discourage failures due to external loading as their effect is additive in nature.

There’s a need for a systematic solution which utilised capability of technology in measuring residual stresses and treatment of residual stresses. Ultrasonic Impact Treatment Solutions (UITS) technique is a combination of two methods in the field of non-destructive testing before treatment utilizing Contacting Metal Magnetic Memory (MMM) and after treatment utilizing Ultrasonic Impact Treatment Solutions (UITS), which is effective for the diagnosis of the residual stresses experience by the ferritic material and a treatment method in reducing the residual stress level.

HOW UITS WORK


  • Involve power levels of hundreds of watts only
  • Amplitudes range from about 10 to 40 microns operating at 20 kHz creates a cyclic acceleration of around 50,000 g (g=9.8 m/s2).
  • B & C to transmit the ultrasonic oscillations to the treated material
  • D, strikers made of high-strength materials are used.
  • A combination effects of high frequency simultaneous exposure to ultrasonic oscillations of the treated surface produce unique beneficial effects to the treated metals and welded component.

BENEFITS TO THE ORGANIZATION

Extend material life exposed to fatigue failures, deferring RM millions of CAPEX for asset replacement.
Reduce unplanned operational downtime as problem areas detected and treated online
Preventing crack formation and growth at stress proned areas.
Require minimal energy requirement, small and versatile for application in remote and tight areas.
