Question: A Heavy Duty Equipment Technician needs to make an out-of-position repair weld on a track frame using SMAW. The material is mild steel, and the weld joint has poor fit-up with a gap up to 3 mm. Which electrode type is best suited for both out-of-position welding and bridging gaps effectively?
Answer options:
- E7024 ✅ E6010
- E7018
- E6013
Correct answer: E6010
Explanation: E6010 electrodes have a deeply penetrating, forceful arc and produce a fast-freezing slag, making them excellent for out-of-position welding, bridging gaps, and welding through rust or mill scale. E7024 is for flat/horizontal, E7018 is for all-position but not as gap-tolerant as 6010, and E6013 is general-purpose but less forceful arc than 6010.
