Abstract:
This article presents the results of research on the influence of acid-type welding electrode calcination methods by standard technology in electric furnaces and a new method of calcination in furnaces using functional ceramics radiation on the welding and technological properties of welding electrodes and determining the optimal modes of calcination when exposed to radiation on electrode coatings. The influence of exposure time T exp of radiation exposure on such welding and technological properties of welding electrodes as the breaking length of the arc L bla, the formation of the deposited metal ødp, the formation of a visor at the end of the electrode h v and pores in the deposited metal N pors, as well as the coefficients of melting αm, surfacing αs and loss of carbon and spattering Ψ was studied. According to the results of the research, the improvement of welding and technological properties during the piercing of welding electrodes by a new method, which consists in processing the coatings with an electrode in a furnace using radiation with functional ceramics at the optimal exposure time T exp. This method of calcining welding electrodes using functional ceramic radiation allows you to obtain high-quality welding and technological properties of coatings, while saving energy consumption and reducing the time of calcination compared to standard technology.
