Purpose: In the paper there were presented possibilities of combining metal sheet with metallic foams using a Nd:YAG laser. Design/methodology/approach: The research were carried out over the properties of laser welded joint of micro-welds iron foam with superalloy HYNESH230®. Findings: The results indicated that there is a possibility of obtaining the satisfying quality joint between the Fe foam and superalloy Hynes H230®. Research limitations/implications: The studies mainly focused on the microstructural and some mechanical properties. Example of structural applications for metallic foams, utilizing benefits in weight, stiffness, energy dissipation, mechanical damping, and vibration frequency were summarized already by many authors. The authors chose to study selected properties of fusion of Fe foam and sheet metal with new approach. Originality/value: The studies used to determine basic quality parameters of the welded joint. Using EDS analysis, there were identified a types of alloying elements and the extent of diffusion from superalloy H 230® in the course of Fe foam. Also, there was investigated shear strength of obtained micro-welds.
