UIT is a relatively new post-weld improvement technique achieved by applying high frequency mechanical impacts in combination with ultrasonic oscillations in the treated welded joints. The fatigue strength improved by UIT is attributed to the improved weld toe geometry, micronized metal structures of the weld toe surface and induced beneficial compressive residual stress.
Metal components and structures treated with UIT benefit from superior fatigue life. Extending fatigue life gives the owner increased return on investment, especially on ageing assets. It does so while saving time and money spent on redesign, repair, or replacements.
Global Energy Ventures can offer clients the recognised benefits of steel structure life extension, especially on offshore vessels, with our portable UIT equipment and trained personnel.
