Appication of the Complete Material Balance Method to Estimate the Transition of Elements in Flux Cored Arc Welding

The paper addresses mathematical models of element transition into overlaying metal and weld metal in different methods of arc welding: stir welding, welding taking account the transition coefficients, empirical, kinetic, and thermodynamic welding. Their comparative analysis is made, their advantages, disadvantages, as well as various applications, are demonstrated. The approach to creation of mathematical models of manual arc welding with coated electrodes and flux cored wire, based on the method of complete material balance, is grounded.
