NON-DESTRUCTIVE TESTING METHOD FOR INCOMPLETE FUSION DEFECT, AND TESTING STANDARD PART AND MANUFACTURING METHOD THEREFOR

摘要

Disclosed are a non-destructive testing method for an incomplete fusion defect, and a testing standard part (10) and a manufacturing method therefor, which are used for non-destructive testing of an incomplete fusion defect of an additive manufacturing workpiece. The manufacturing method for an incomplete fusion defect standard part (10) comprises: step A, setting an incomplete fusion defect area (2) of a standard part (10), wherein in the incomplete fusion defect area (2), the proportion of an incomplete fusion defect in the incomplete fusion defect area (2) is set as a first proportion value; step B, selecting an additive manufacturing forming process for manufacturing the incomplete fusion defect area (2), and obtaining a first process parameter of the additive manufacturing forming process corresponding to the first proportion value; and step C, performing the additive manufacturing forming process on the basis of the first process parameter to form the incomplete fusion defect area (2). The non-destructive testing method for an incomplete fusion defect improves the accuracy and reliability of results of the non-destructive testing for the incomplete fusion defect of the additive manufacturing workpiece.
