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 formation and detachment of relatively large molten droplets from the wire tip. Because these droplets are large, the transfer tends to be less smooth and more prone to spatter, and it typically occurs at lower welding currents and voltages with modest shielding gas flow. This is in contrast to spray transfer, which uses many tiny droplets produced at higher current and usually higher shielding gas flow.

That’s why the statement about large droplets best describes globular transfer. The idea that it uses small droplets would align with spray transfer, not globular. The notion that it requires very high shielding gas flow is more characteristic of spray transfer as well, not globular. And saying globular transfer is never used in any position isn’t accurate, as it can be used in several positions, though it’s often less favorable for vertical and overhead welds.
