Abstract

A tandem welding system includes a plurality of spaced apart electrodes (12, 14, 16, 18) arranged to travel at a common travel speed. The plurality of spaced apart electrodes (12, 14, 16, 18) cooperatively perform a weld. A data storage medium (74) stores measured data for each electrode during the performing of the weld. A processor (110) performs a process comprising: for each electrode, recalling measured data corresponding to the electrode passing a reference position; and, combining the recalled measured data of the plurality of spaced apart electrodes (12, 14, 16, 18) to compute a weld parameter of the tandem welding system at the reference position.
