A multi-ply sealing ring and method of manufacturing same. Two annular members are nested one within the other and then welded together at equi-distant intervals to form a plurality of annular weld zones. The two annular members are then cut along the weld zones to form a plurality of multi-ply cylindrical bands having weld-sealed opposite axial ends. Each cylindrical band is then formed to include a sealing profile.
