AWS A5.28 ER80S-Ni1 Solid wire
TEMO WH55Ni1, GB/T 8110 G55A4HM21SN2 NB/T 47018.3 ER55Ni1
Description:
ER80S-Ni1 is a 550MPa grade fine-grained steel gas shielded solid wire, which uses rich argon gas protection and has excellent welding process performance. It has stable arc combustion, small spatter, and beautiful weld formation. Due to the presence of a certain amount of Ni element in the welding wire, the weld metal has excellent low-temperature impact toughness.
Diameters: Packaging:
0.6mm-4.0mm 1kg, 5kg, 15kg, 250kg, 300kg, 350kg
Applications:
Mainly used for welding low-alloy steels with high requirements for low-temperature toughness (-45 ℃).

Notes:
1. Using mixed gas protection, gas code M21 (Ar+(15-25%) CO₂).
2. The dry extension length of the welding wire should be controlled within the range of 15-20mm.
3. Before welding, impurities such as rust, oil stains, and moisture must be removed from the welded parts.
4. After unpacking the wire, attention should be paid to taking moisture-proof measures and using it up as soon as possible.
5. When welding on site, if the wind is too strong, windproof measures should be taken.
