This paper demonstrates a simple and effective technique for friction spot brazing of stainless steel (st37) to titanium (grade 1). We use aluminum foil as a filler that is placed between the base metals. We evaluate the joints when using different rotational speeds: 1800, 2000, 2200, 2400, 2600, and 2800 RPM. We characterize the joint using scanning electron microscopy, optical microscopy, energy dispersive X-ray analysis, the microhardness of cross-sections, and fractography. We found that the strongest tensile strength joint (6 kN) comes from friction spot brazing at 2000 RPM. The joint interface of the 2000~RPM sample contains intermetallic compounds such as FeTi, Fe3Al, FeAl2, and Ti3Al, which increases the tensile strength.
