Abstract

A pesar de haberse estudiado y aplicado electrodos con recubrimientos múltiples, en la literatura consultada no se ha referido suficientemente el efecto del cambio de posición de la carga de aleación, dentro del recubrimiento de electrodos destinados al relleno, sobre su comportamiento operativo. Como objetivo del trabajo se determinó la influencia de la posición relativa de la carga de aleación en la estructura del recubrimiento de los electrodos destinados al relleno superficial sobre la estabilidad del arco y el consumo de potencia, a partir del análisis, procesamiento y comparación de los oscilogramas eléctricos de los procesos de soldadura aplicados. Para ello, se realizó un estudio de los oscilogramas de voltaje y corriente de cada variante de electrodo preparada: mismas composiciones de núcleo, carga de aleación y recubrimiento; solo se cambió la posición en que se encuentran. Como resultado se apreció diferencias en la estabilidad y consumo eléctricos del proceso.

Palabras claves: electrodos doblemente recubiertos, oscilogramas eléctricos, relleno superficial, soldadura.

Abstract

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.

Key words: doubly coated electrodes, electric oscillograms, hardfacing, manual metal arc.
