Application of the Complete Material Balance Method to Estimate the Composition of Weld Metal in Manual Arc Welding

Abstract:

The article addresses the mathematical model of manual arc welding with coated electrodes, based on complete material balance, the model is a three equation system. The first equation describes the interaction between average and partial transition coefficients; the second equation shows the transition of an element from the metal phase; the third one characterizes the reduction of an element from the slag phase. The results of modeling for base and rutile electrode are given. The convergence of experimental data and calculations is shown. The regressionequations to calculate the parameters required for forecasting the composition of overlaying metal and weld metal in manual arc welding are listed.
