Abstract. In previous studies, composite metal foams (CMF) have shown exemplary mechanical performance under impact which has made them prime candidates for protection of transported passengers and cargo. [1] Materials utilized in such applications often require joining to form structures and geometries that are far more complex or impossible to produce in an as-manufactured state. Welding methods are popular in the joining of metals with solid-state welding processes such as induction welding being of particular interest in the studies to be discussed. In this study, various thicknesses of 316L stainless steel CMF are manufactured through powder metallurgy technique and welded using Induction Welding. The mechanical properties of the weldments were studied through uniaxial tensile tests while microstructural characterization of the weldment within the joint interface and heat-affected zone (HAZ) are evaluated using scanning electron microscopy. The combination of these evaluations grant insight on the effects of various weld parameters (e.g., welding temperature, workpiece thickness, flux, and welding environment) as well as the suitability and restrictions of induction welding in the joining of 316L Stainless Steel CMF.
