Embodiments of welding work cells are disclosed. One embodiment includes a workpiece positioning system, a welding power source, and a welding job sequencer. The workpiece positioning system powers an elevating motion and a rotational motion of a workpiece mounted between a headstock and a tailstock to re-position the workpiece for a next weld to be performed. The welding power source generates welding output power based on a set of welding parameters of the power source. The welding job sequencer commands the workpiece positioning system to re-position the workpiece from a current position to a next position in accordance with a next step of a welding sequence of a welding schedule. The welding job sequencer also commands the welding power source to adjust a current set of welding parameters to a next set of welding parameters in accordance with the next step of the welding sequence of the welding schedule.
