Abstract
This article discusses the influence of multipass welding with several electrodes of different brands on the chemical composition and microstructure of the seam. The objects of study were samples of pipe section made of stainless steel grade 12X18H10T. As a result of the conducted research, the values of the effective thermal power of the heating source were established, ensuring a uniform distribution of elements in the deposited metal, an austenitic structure, a minimum content of the ferritic phase and a uniform distribution of microhardness over the seam section.
