Question: A welder is tasked with joining two heavy steel plates in the 3G position using SMAW. The project requires high deposition rates and good mechanical properties for structural integrity. Which electrode would be the most suitable choice for this application?
Answer options: ✅ E7018
- E6010
- E7024
- E6013
Correct answer: E7018
Explanation: E7018 electrodes are known for their high deposition rates, good mechanical properties, and excellent out-of-position welding capabilities, making them ideal for structural applications in vertical positions like 3G. E6010 is good for root passes and deep penetration but has lower deposition, while E7024 is for flat/horizontal only and E6013 offers less strength and penetration.
