Globular transfer is often used for welding metal more than 1/2 inch thick.

Globular transfer is often used for welding metal more than 1/2 inch thick.

• A. True
• B. Partially true
• C. False
• D. Depends on material

Answer: (C)

Globular transfer relies on large molten droplets that detach irregularly, making the arc unstable and producing significant spatter. When welding thicker metal, you need a stable arc with good penetration and clean welds, which is best achieved with spray or pulsed-spray transfer and often with an argon-rich shielding gas. Because globular transfer is irregular and tends to have poor control over heat input and penetration, it isn’t typically used for metal thicker than about 1/2 inch. So the statement is not true; thicker sections are better welded with spray/pulsed transfer rather than globular.
