What is the difference between globular and short-circuit transfer? Short-circuit is a mode of metal transfer in GMAW in which metal is transferred from the electrode to the weld pool via a series of electrical shorts. When the electrode (wire) touches the base material a short occurs and the arc goes out. At this point […]
Spray is a mode of metal transfer in which a fine spray of metal droplets are projected axially from the tip of the electrode to the work. These droplets are smaller in diameter than the electrode. This mode of transfer is characterized by high wire feed speeds (high amperage), high voltage and consequently high heat […]
In our last post we explained short circuit transfer; if you missed it you can go back and read Modes of Metal Transfer: Short Circuit. In this post we’ll spend some time going over globular transfer by covering its basics as well as its advantages and limitations. Globular transfer occurs in GMAW and MCAW processes […]
