The problem of defects in casting is widespread throughout the foundry industry and their detection is of paramount importance in maintaining product quality. Defects are caused because the metal is weak when it is hot and the residual stresses in the material can cause the casting to fail as it cools. Various defects observed are blowholes, misrun, drops and pores that greatly influence the material ability to withstand various loads. Defects act as region for stress concentration initiating crack. Ultrasonic testing is used to determine these defects. But this inspection method is slow and expensive. In order to minimize the cost and speed up the inspection process, acoustic emission technique is used.
