Title

Utilization of Special Characteristics in the Manufacturing of Additive Manufacturing Parts for Precise Calibration of Ultrasonic Test Equipment

Pages

  27-40

Abstract

 In order to utilize NDT methods to evaluate manufactured parts via Additive Manufacturing (AM), scales are needed to represent probable defects in the produced part. In light of common defects in AM produced parts (gas porosity, powder porosity lack if fusion, etc. . . ) and difference in their forming mechanism with probable defects in parts manufactured via traditional means, using present Calibration Blocks are not very effective. In the presented paper herein, an innovative reference block with designated internal characteristics for the calibration of ultrasonic equipment has been designed and manufactured by SLM method. Then, it was tested by pulse-echo ultrasonic test method. To attain confidence in the precision and accuracy of designated characteristics, cutting of the part took place and their dimensions was measured by light microscope and their distance from free surface by micrometer. To obtain results indicated affirmation in dimensional accuracy and precision and hence their utilization as a reference block in BDT measurement was confirmed.
