The weld cylinder will not provide the proper range of electrode force or motion.
The weld cylinder serves two primary functions:
- The cylinder stroke separates the electrodes to allow part access
- The cylinder closes the electrodes on the workpiece to provide the required welding force
- The following is a basic list of cylinder characteristics which must be considered for proper equipment function: bore, stroke, single or dual action, type (air, hydraulic, or hybrid), seal type, shaft length, overall length, mounting details, cushions, etc.
Detectable evidence may include:
Quality, Workplace Issues, Cost, Downtime, Maintenance, Throughput (cycle time; PPH), are all potentially affected by this condition.
- Correct cylinder unavailable
- Improper maintenance
- Incorrect nameplate
- Incorrect rework
Note: Similar considerations may be applied to servo motor systems.
