Inclusion in casting is internal defect
Web2.Inclusion defects 2.1 Slag inclusion is a defect where non-metallic materials create pockets or ribbon-like entrainments in the casting. Slag is an important part of the melting process in the furnace, necessary for good quality castings, as chemical processes in silica and calcium-based slags change the viscosity of the metal. WebDetect Internal Defects in Castings by Ultrasonic Ultrasonic testing can find defects such as shrinkage cavities, shrinkage porosity, porosity, inclusions, and cracks in castings with simple shapes and flat surfaces, and can determine the size and location of defects.
