What Is the Difference Between Spray Transfer and Globular 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. Short circuiting metal transfer occurs during rapid short circuits with the molten weld pool.

What is spray transfer mode?

Spray transfer As its name implies, the spray mode generates a spray of tiny droplets (smaller than the wire diameter) across the arc to the weld pool, which increases deposition rates, provides good fusion and penetration, and creates little spatter. The transfer mode also generates a good weld bead appearance.

Can you spray transfer in all positions?

Due to its highly directed stream, spray transfer can often be used in any position. That is, the workpiece is not required to be below the torch. Also, pulsing of the welding current (see Figure 2.5) is often used for spray transfer processes.
