The Benefits


Stress Corrosion Cracking – UIT can be used to mitigate the effects of Stress Corrosion Cracking (SCC) The UIT process can be used on most materials susceptible to SCC to minimize and/or arrest the propagation of SCC.


Distortion Mitigation – When UIT is applied to welded surfaces, it neutralizes the tensile stress created during welding and relaxes the welded structure reducing and or eliminating distortion/


Fatigue Life Extension – Upon application of UIT to the weld toe, the weld toe geometry is modified creating a fatigue friendly geometry. Compressive residual stress is imparted into the heat affective zone (HAZ) improving grain structure ad strength.
