TESTING OF ALUMINIUM CASTINGS WITH ADVANCED ULTRASONIC FLAW DETECTOR – AS414
Non-destructive testing using ultrasonic measurement is used to ensure the quality of Aluminium-casting products. The quality of a casting depends on the presence of discontinuities such as porosity and on the final metallurgical structure. Discontinuities occurring in the sub-surface of the cast structure mostly have irregular surfaces which scatter the ultrasound waves and make ultrasonic testing[…]

Bond Testing between FRP and Rubber in Power Grid Insulators
In power grid insulators, fibre-reinforced plastic/polymers (FRP) and rubberised materials are fused together. If the interface bonding is not uniform, the distribution of the electric field will be adversely affected, which accelerates the ageing of composite insulators and thus, affects the safe operation of transmission lines. Hence, it is important to inspect the bonding between the FRP[…]
