Abstract:
1. The method for applying a compensatory weight to a drive shaft having a longitudinal axis comprising: a. Securing said drive shaft in a known relationship to an imbalance sensor and a welding means, said welding means for welding having a pair of electrodes; b. Rotating said drive shaft in proximity to said imbalance sensor; c. Determining an out-of-balance condition of said drive shaft; d. Rotationally positioning said drive shaft in relation to said welding means; e. Positioning said pair of electrodes in longitudinally-spaced positions on said drive shaft, and positioning said pair of electrodes on substantially the same radial position on the circumference of said drive shaft; and f. Delivery of at least one compensatory weight to said welding means; and g. Welding said weight to said drive shaft.
