Abstract
Experiments are described on determination of voltage drop in the area of electrode wire contact with the welding torch nozzle. Results of computer processing of experimental data were the basis to suggest empirical formulas of contact voltage drop dependence on different welding parameters.
Keywords: arc welding, contact voltage drop, contact resistance
