Welding Metal Transfer. Detaching Force - electrode pointed downward Retaining Force electrode pointed upward 7. Metal transfer with CO 2 welding is considerably improved by the addition of alkali metal compounds like cesium and sodium to the welding wire.
Short Circuit Transfer is typically used for metals of thinner thickness whereas Spray Arc Transfer is used for thicker metals. Metal transfer from additional filler wire takes place when such a wire or rod is used as in gas tungsten arc welding plasma arc welding and the oxy- fuel gas welding. To improve quality flexibility and productivity of the welding performance the process automatization using welding robots is important.
This welding technique is commonly known as globular transfer with metal transferring through the arc.
Metal transfer from additional filler wire takes place when such a wire or rod is used as in gas tungsten arc welding plasma arc welding and the oxy- fuel gas welding. The transfer of molten metal from the tip of electrode to base metal. Short Circuit Transfer is typically used for metals of thinner thickness whereas Spray Arc Transfer is used for thicker metals.
