The present paper describe the progress achieved in an ultrasound system designed to scan cord welds by means of the Time of Flight Diffraction technique TOFD. An increase in the speed of the exploration will be show when comparing it to previous. With the application made ​​it is possible to generate a D-Scan image almost immediately. To achieve these images a program written in Matlab platform was designed and implemented, so that having this tool reduces computational task to move an array of transducers on a straight path parallel to the region you want to examine. Once the signals are stored, the program designed handles to their respective alignment and then builds with these two-dimensional image in which the profile of potential discontinuities embedded in the cord weld are displayed
