ABSTRACT:
This invention is an annular or garter spring having a welded overlapping region. In this invention, the end tips of a straight spring fit within the spaces between coils at the opposite end of the spring. This result is reached by first hooking an end tip of the spring through the first whole coil at the opposite end of the spring, then placing the opposing end tip between the first and second full coils of the first side of the spring. The coils at the ends of the spring are then clamped to so that each end tip aligns alongside the first full coil of the opposite end of the spring. When that position is reached, the spring will form a virtually perfect ring, and the intertwined coils may be welded together to maintain the garter spring shape.
