Abstract
The method includes providing a source of flat stock; forming the flat stock into a spherical shaped bead that includes connected semi-spherical bead halves with each half having opposed open recesses that are located in a circular edge that defines each semi-spherical half; providing a source of wire stock; forming the wire stock into a series of the interconnected links with each link having a middle section and contiguous opposed enlarged ends at respective ends of the middle section; positioning the formed links each between adjacently disposed spherical shaped beads for accommodation in facing recesses thereof; closing the connected semi-spherical bead halves to form the spherical shaped bead; and laser welding between the connected semi-spherical bead halves.
