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 […]
The modes of metal transfer refer to the different ways in which the filler metal (electrode) is transferred through the welding arc and into the weld puddle. We can write a book on this topic but we’ll keep it simple to provide an understanding of the different modes of transfer, what they require and what […]
We are frequently asked if there are any real benefits of using pulse over CV in the MIG process. The short answer is “absolutely.” But before we can answer we need to ask: “what is the application?” To really appreciate the benefits of pulsed GMAW compared to traditional CV (short arc or globular) it is […]
