Resumen

GONZALEZ-CABRERA, Odonel; GOMEZ-PEREZ, Carlos R.; KAIRUS-HERNANDEZ-DIAZ, Héctor Arturo  y  VAZQUEZ-BADILLO, Elizabeth. Electric oscillogram's comparison when hardfacing with double coated electrodes. Ingeniería Mecánica [online]. 2016, vol.19, n.3, pp.128-136. ISSN 1815-5944.

In spite of having studied and applied electrodes with multiple coatings, in looked up literature the effect of the alloy change position, within the coating of electrodes destined to the hardfacing, on operating behavior has not been sufficiently referred. As objective of work determined the influence of the alloy charge position in the coatings of electrodes destined to hardfacing on the stability of the arc and the power consumption of the process, as from analysis, processing and comparison of electric oscilograms of the welding processes applied itself. For that, a study of the voltage and current wavesgive out by each variant of electrode prepared were accomplished: Same compositions of metallic core, alloy charge and coating; only has been changed the position of alloy charge. As a result, differences in stability and electric consumption of the processare appreciated.

Palabras clave : doubly coated electrodes; electric oscillograms; hardfacing; manual metal arc.
