The Procedure for Quantitative Analysis of Welded Joints in QE22 Alloy

Abstract:

The work presents the procedure for a quantitative description of the structure of a welded joint of QE22 alloy, welded with TIG method. The developed procedure includes a sampling strategy, methodology of revealing the structure and a set of image conversions necessary to conduct the quantitative assessment. One been observed a repeated fragmentation of the a(Mg) grain and fragmentation of the eutectic areas in the fusion weld, compared to the post-casting material. It results from the conditions of the fusion weld crystallization. The statistical analysis has shown that the developed procedure ensures repeatable and clear presentation of the structure of the QE22 alloy welded joint.
