Inductive thermography is a non-destructive testing method, whereby the specimen slightly heated with short heating pulse (0.1–1 s) and temperature change on surface recorded an infrared (IR) camera. Eddy current induced by means of high frequency (HF) magnetic field in ‘skin’ specimen. Since cracks disturb eddy distribution heat diffusion, they become visible IR images. Head checks squats are ...

stress and residual stress are the main problems in the operating performance of materials. they are the principal causes of material failure and can affect life time of component. however measurement or predictions of them are typically difficult. two common non-destructive methods, x-ray diffraction and ultrasound are not reliable methods for subsurface residual stress measurements and destru...

Installation of concrete pavement at the curb travel lane bus stop is a common way to improve resistance pads environmental and petroleum deterioration in Canada. The Satisfactory condition pavements remains key consideration development infrastructure, especially countries with an aggressive environment. Innovative materials that could remarkably increase service life infrastructure are being ...

High-temperature pressure pipelines are extensively used in petrochemical plant and power stations. Severe pits or wall loss defects can be internally produced after a certain period of time due to media corrosion and cavitation erosion. These defects finally lead to leakage of the pipes. In order to search for a good non-destructive method for these defects, a large pipe testing installation w...
