A method of welding brush filaments to a ferrule that includes the steps of providing a welding source that produces high frequency vibrations and/or heat, brush filaments, and a ferrule having an inner face, an outer face and an opening to receive the brush filaments, positioning the brush filaments at least partially into the opening of the ferrule, positioning the welding source proximate the outer face of the ferrule, and transferring the high frequency vibrations and/or heat from the welding source to one or more locations on the outer face of the ferrule.
