Scope

This CWA states a set of guidelines to control the quality of metal Additive Layer Manufactured (ALM) parts in terms of existence of defects by using ultrasonic technique. With the aim of characterizing the material in the aspects most relevant to the inspection, the measurement of some relevant acoustic parameters of the layered material is proposed first. Secondly, the most important configuration parameters are gathered together with a range of example values. After that, a set of specific guidelines for the automatic inspection under in-line conditions is provided. Finally, the specific highlights and restrictions coming from in-service conditions are explained.
This CWA does not include the basic vocabulary and general configuration and calibration steps for ultrasonic inspections, which are specified by the referenced general standards.
This CWA is not a testing procedure, because the specific parameters and scanning steps depend on each particular material and geometry of the part.
The information provided in this document is based on the results of the BIONIC AIRCRAFT research project.
