Earliest metal transfer mode gmaw
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. WebJun 1, 2012 · One of the most characteristic phenomena of gas metal arc welding (GMAW or MIG/MAG) is molten droplets transferring across the arc from the wire electrode to the liquid weld pool. Different transfer behavior, referred to as “droplet transfer mode”, can be observed Influenced by, e.g., growth time, dimension and detachment frequency.
