In a short circuit transfer how is the metal transferred to the base metal?

• A. as solid wire
• B. as molten droplets
• C. as gas
• D. as flux

Answer: (A)

In short-circuit transfer, the metal that moves to the base metal is in the form of tiny molten droplets. The welding arc causes the wire tip to touch the work and melt, forming a small molten ball that is drawn across the arc to the weld pool. When the short opens, another droplet forms and repeats this cycle. So the actual material transferred is molten metal from the electrode tip, not the solid wire itself. Shielding gas or flux don’t carry metal across the arc, and the wire isn’t transferred as a solid piece.
