Construction of a short circuit frequency map to define GMAW-S parameters during WPSs development

A short circuit frequency map was constructed for GMAW-S using a carbon steel filler metal class AWS ER70S-6 and 75%Ar-25%CO2 shielding gas. This kind of map is proposed as a tool for selecting GMAW-S currents and voltages that enable welds with higher stability and quality. The map was constructed...

This kind of map is proposed as a tool for selecting GMAW-S currents and voltages that enable welds with higher stability and quality. The map was constructed by analyzing current and voltage signals recorded during welding applications at 5000 samples/second. Adequate operation regions were defined over the map based on visual inspection results of bead-on-plate welds and the establishment of instability boundaries. Some examples were analyzed by locating two common parameters for industrial welding qualification (current and voltage) and drawing the limits established by AWS D1.1:2015 code for these essential variables (±7% PQR voltage and ±10% PQR amperage) on the frequency map. The results show that sometimes these limits may contain regions with poor stability related to electrode stubbing against the base metal and lack of arc re-ignition.Se construyó un mapa de frecuencias para GMAW-S usando un aporte clase AWS ER70S-6 y gas de protección 75%Ar-25%CO2. Este tipo de mapa es una herramienta para seleccionar corrientes y voltajes de soldeo con proceso GMAW-S con mayor estabilidad. El mapa se construyó analizando señales de voltaje y amperaje registradas durante la aplicación de soldaduras a 5000 muestras por segundo. Se definieron regiones de operación sobre los mapas basados en resultados de inspección visual de soldaduras sobre platina y ubicando los límites de inestabilidad. Se analizaron dos ejemplos de parámetros de calificación de soldaduras usados industrialmente (corriente y voltaje) dibujando los límites establecidos por el código AWS D1.1:2015 para estas variables esenciales (±7% en voltaje y ±10% en amperaje del PQR) en el mapa de frecuencias. Se mostró como estos límites pueden contener regiones de baja estabilidad asociada al “stubbing” contra el metal base y al no reinicio del arco.application/pdfspaUniversidad Nacional de Colombia - Sede Medellín - Facultad de Minashttps://revistas.unal.edu.co/index.php/dyna/article/view/69256Universidad Nacional de Colombia Revistas electrónicas UN DynaDynaHoyos-Arango, David Bernardo and Giraldo-Barrada, Jorge Enrique and Mejía-López, Oscar León (2018) Construction of a short circuit frequency map to define GMAW-S parameters during WPSs development.
