Abstract
Welded metal porosity significantly influences the mechanical properties of dissimilar metal joints. In this study, the comparison of porosity evaluation methods was held using the sample of welded-brazed zinc coated steel and Al-Mg-alloy plates joint. Relative porosity was measured through cross-sections’ images area analysis, as well as it was evaluated through 3D-fitting of spotted on these images pores. Area and size of pores was measured, volume and distribution were evaluated. It was found that relative porosity values estimated by 2D and 3D methods are equal.
