BLUME® ER80S-Ni2 (TIG) Datasheet

Q: What makes BLUME® ER80S-Ni2 different from ER80S-Ni1?
A: BLUME® ER80S-Ni2 contains twice the nickel content (2.0%), offering higher toughness and ductility for ultra-low temperature applications such as LNG and cryogenic systems.

Q: What shielding gas is recommended?
A: Use 100% Argon for best arc stability and weld purity during TIG welding.

Q: Is post-weld heat treatment required?
A: It depends on the base metal and design requirements. However, BLUME® ER80S-Ni2 maintains excellent mechanical properties in both as-welded and stress-relieved conditions.

Q: Can it be used for both root and fill passes?
A: Yes. Its smooth puddle control and excellent penetration make it ideal for all welding positions.

Q: Why choose BLUME® filler metals?
A: BLUME® TIG rods are precision-engineered for maximum consistency, weld purity, and performance, helping welders achieve stronger, cleaner, and more reliable welds—every time.
