An analytical model is developed to predict the temperature profile and weld pool geometry in double-electrode gas metal arc welding (DE-GMAW), which is invented to avoid unwanted side-effects resulting from the higher welding current associated with higher wire melting rate. For a case study, the DE-GMAW process employs the wire melting current of 250 A while maintains the base metal current at half of that value. Through preliminary analysis, quantitative information is obtained for the deposition area, arc pressure, weld pool geometry, and the region at elevated temperature in the DE-GMAW.
