Abstract

Las correcciones de arco y de pulso del proceso de soldadura con transferencia metálica fría modifican el voltaje y la corriente. El efecto de su combinación no se ha estudiado suficientemente sobre la geometría de la unión. El objetivo del presente trabajo es determinar el efecto de las correcciones de arco y de pulso y de la velocidad de soldadura del proceso con transferencia metálica fría sobre las geometrías de las uniones realizadas en aluminio 5083.Para ello, se realiza un diseño experimental, con tres factores independientes a dos niveles, empleando los parámetros geométricos de las uniones como factores independientes. La función corrección del puso influye directamente sobre la altura y la profundidad, mientras que la función corrección de la longitud de arco influye inversamente. Ambas funciones no manifiestan influencia significativa sobre el ancho del cordón. La velocidad de soldadura influye inversamente sobre la altura, el ancho y la profundidad de los cordones de soldadura.

Palabras claves: corrección de arco, corrección de pulso, transferencia metálica fría, geometría de la unión.

Abstract

The arc and pulse corrections of the cold metal transfer welding process modify the voltage and current. The effect of their combination has not been sufficiently studied on the joint geometry. The objective of the present work is to determinate the effect of the arc and pulse corrections and the welding speed of the cold metal transfer welding process on the 5083 aluminum joints geometries. For this, an experimental design is made, with three independent factors at two levels, using the geometric parameters of the unions as independent factors. The correction pulse function directly acts on the height and depth, while than the arc length correction function has inversely influence. Both functions do not manifest significant influence on the welding width. The welding speed inversely acts on the height, the width and the depth of the welding joint.

Key words: arc correction, pulse correction, cold metal transfer, joint geometry
