Which of the following is NOT a type of arc transfer?

• A. Pulsed Transfer
• B. Short Circuit
• C. Continuous Transfer
• D. Spray Transfer

Answer: (C)

Continuous transfer is the correct answer because it is not classified as a type of arc transfer used in welding processes. In welding terminology, arc transfer refers to the various methods by which the welding filler material is transferred across the arc to the base metal. Pulsed transfer, short circuit, and spray transfer are all established methods. Pulsed transfer involves controlling the heat input and is characterized by a periodic increase and decrease in the welding current, allowing for better control over the weld pool. Short circuit transfer occurs when the electrode touches the workpiece, creating a circuit that momentarily shorts out the arc, which is typical in lower current welding for thin materials. Spray transfer, on the other hand, involves a continuous stream of molten droplets of filler material propelled across the arc due to high welding current, leading to a high-speed transfer suitable for thicker materials. In contrast, continuous transfer is not an accepted term in the context of arc transfer methods. By understanding these distinctions in terminologies and techniques, one can engage with welding processes more effectively.
