Reduction of material and energy welding and assembly of loss in limited experimental sample
Consumption of welding electrodes, power and performance and installation works to a large extent determined by the technical and operational characteristics of the electrodes: the deposition rate, the loss resistance of the arc. The article presents the results of experimental research and statistical analysis with the specification of indicators most widely used brands of electrodes ELN-21 Monolith RC and MP-3. Significance of differences of sample averages of each of the groups tested brands of elec-trodes allowed them to identify the optimal combination of matching the most powerful technical and economic characteristics that minimize material and energy losses, increase the accuracy of calcula-tions and the accuracy of the final results of the planned welding and assembly work to be performed by the electrodes of a certain brand, more appropriate for specific welding operations.
