Validation of evaporation-determined model of arc-cathode coupling in the peak current phase in pulsed GMA welding

Validation of evaporation-determined model of arc-cathode coupling in the peak current phase in pulsed GMA welding

A first experimental validation of the evaporation-determined arc-cathode coupling (EDACC) model is performed by comparing the experimental and simulated current in the peak current phase of a pulsed gas metal arc welding process. For this, the EDACC model was extended to limit the cathode surface t...

Zusammenfassung:A first experimental validation of the evaporation-determined arc-cathode coupling (EDACC) model is performed by comparing the experimental and simulated current in the peak current phase of a pulsed gas metal arc welding process. For this, the EDACC model was extended to limit the cathode surface temperature to a realistic value of
