FAQ
FAQ
Q: What base metals can BLUME® E9015-B3 be used on?
A: Designed for low-alloy, high-strength steels, ideal for structural, pressure vessel, and heavy machinery applications.
Q: Can it be used in all welding positions?
A: Yes. BLUME® E9015-B3 is excellent for flat, horizontal, vertical, and overhead welding.
Q: How does BLUME® E9015-B3 differ from E8018-G?
A: E9015-B3 is formulated for higher tensile strength and low-hydrogen performance, while E8018-G is optimized for productivity and deep penetration on HSLA steels.
Q: Is it suitable for low-temperature or cold-weather welding?
A: Yes — it maintains high toughness and ductility even in sub-zero environments.
Q: How should the electrodes be stored?
A: Store in a dry, temperature-controlled environment. If exposed to moisture, rebake at 650°F (340°C) for 1 hour before use.
