FeCo-V alloys are one of the most important groups of magnetic material which currently used in high speed engines due to their excellent magnetic and mechanical properties. Welding of these alloys is a great challenge since various phase transformation result in significant changes in magnetic and mechanical properties. In this research ultra-thin FeCo-V magnetic foils were welded using laser and electron beam welding processes. After development of mathematical models, working limits of process parameters were chosen to obtain welded joints which have simultaneously appropriate maximum energy product and mechanical strength.
