Abstract
A welded bellows is formed by welding together a stack of annular elements such that spacer rings are located between adjacent elements at the inner and outer diameters and are the locations for the welds. The spacer rings eliminate very small clearances/contact between movable members which can be the locations for stress risers in the presence of dirt.
