초록
In this paper, we present a ultrasonic speckle suppression method for centrifugal-casted stainless steel sample by computer simulations of a flaw enhancement algorithm. Because of their practical importance in welds, the ultrasonic signal obtained from heat-affected zone or welds are investigated for computer simulation. The results for computer simulation present the more enhanced flaw-visibility and speckle suppression than the compared two techniques.
