Features of Radiographic Inspection of Castings from Aluminum Alloys of Silumin Cluster

E. I. Kosarina, O. V. Govyadovskaya, N. Ya. Matsan

Silumin aluminum casting alloys have a specific defect — porosity. A feature of the radiographic inspection of castings from alloys of this group is that the evaluation of the suitability of the product is carried out on the x-ray scale of the reference radiographs. The article shows that the selection of modes, parameters and means of radiographic inspection, especially the choice of radiographic film, must comply with the regulation of normative and technical documentation and the rules for using the scale of reference x-ray images. Failure to comply with these conditions may lead to an incorrect assessment of porosity and the omission of an unacceptable defect.
Keywords: alloys of the silumin group, porosity, X-ray scale of reference radiographs, radiographic film
