Which statement about globular transfer is true?

• A. Globular transfer uses small droplets.
• B. Globular transfer uses large droplets.
• C. Globular transfer requires very high shielding gas flow.
• D. Globular transfer is never used in any position.

Answer: (B)

Globular transfer is defined by the size of the molten metal droplets that form at the wire tip. In this mode, the droplets are large and globular, detaching under gravity and entering the weld pool. That large droplet size makes the arc less stable and produces more spatter, which is a hallmark of globular transfer. This is why the statement that globular transfer uses large droplets is true. In contrast, small droplets are characteristic of short-circuit transfer, and very fine droplets are associated with spray transfer, which also relies on higher shielding gas flow. The idea that globular transfer requires very high shielding gas flow isn’t accurate, and globular transfer can be used in some positions (it isn’t limited to no positions at all).
