The present invention generally relates to corrosion protection of continuous sucker rod weld zones. In one embodiment, a method of manufacturing a continuous sucker rod is provided. The method includes acts of fusing adjacent free ends of adjacent rods together to form one continuous length of rod, said fusing creating a weld zone; treating the weld zone to resist corrosion in a wellbore environment; and winding the continuous length of rod into the continuous sucker rod coil.
