Abstract
A weld monitor system measures and records physical conditions under which welds are made between parts weld fused by an automated welding machine. Analog data of pressure in hydraulic circuits of hydraulically driven operations of an automatic welding machine, and analog data of weld current amperages applied to welding electrodes of the welding machine is acquired and stored by the weld monitor system to provide an archival record of the physical conditions of the formation of all welds made by the automatic welding machine. The weld monitor system compares the data to a predetermined range of values and sends a control signal to a welding machine controller indicative of the results of the data comparisons. An automatic part identification unit of the weld monitor system sequentially applies permanent unique indicia to parts weld assembled so that weld assembly data for uniquely identified parts can be readily retrieved from the stored data. Welding condition data acquired by the weld monitor system provides a broad range source of production process data on which to perform statistical process control analysis.
