WebThe gas metal arc welding process has been used since the mid 1950′s with spray, globular, and short circuiting metal transfer. Spray transfer is characterized by spatter-free axial droplet transfer in an argon-rich shielding gas. The globular transfer mode uses gravity to transfer large globules of molten electrode. WebNov 12, 2009 · Literature recognizes four distinct modes of metal transfer when using GMAW. They are: a) Short circuiting transfer characterized as low heat input, low voltage, low amperage typically using a CO2 Argon mixed shielding gas. Capable of welding in all positions, but fusion type defects are common.
