Globular transfer produces a stable arc, excellent weld appearance, and little weld spatter.

Globular transfer produces a stable arc, excellent weld appearance, and little weld spatter.

• A. True
• B. False
• C. It produces an unstable arc
• D. Requires post-weld cleaning

Answer: (B)

Globular transfer in GMAW sends large droplets from the wire into the weld pool. Those droplets detach irregularly, which makes the arc unstable and tends to create a lot of spatter. The bead appearance is usually rough and harder to control. So the statement that globular transfer yields a stable arc, excellent weld appearance, and little spatter isn’t correct. Techniques that aim for a stable arc and cleaner welds, like spray transfer, rely on smaller, more uniform droplets and result in smoother beads with less spatter.
