Measurement of Dynamic Resistance in Resistance Microwelding of Insulated Copper Wire

Abstract:

A measuring system of dynamic resistance in resistance microwelding (RMW) of insulated copper wire was developed. The system included a computer, data acquisition (DAQ) card, current sensor, digital trigger circuit and analysis software. Dynamic resistance patterns at the secondary circuit under both normal and abnormal welding conditions were successfully monitored by this system. The results show that the dynamic resistance during the RMW of insulated copper wire is a monotonously decreasing curve; a wave crest will appear when surface splash occurred. This peak characteristic can provide a sound approach to in-process monitor weld quality for RMW of the insulated copper wire.
