AK-ER60SD
Standard:
EN ISO ——
AWS A5.28 ER90S-G
GB/T 8110 ER60-G
Characteristics and Applications: AK-ER60SD is low alloy steel copper-plated gas shielded wire, wire melting speed, arc stability, small spatter, beautiful weld shape, weld metal has good mechanical properties. Suitable for welding 600MPa steel structure. Commonly used in the same strength level of hydropower, bridges, petrochemical, engineering machinery, coal mining machinery and other structural steel welding.
Note:
1. The protective gas is rich argon or CO2 gas, the gas flow rate is 15-20L/min.
2. The impurities such as water, oil and embroidery must be removed from the welding place.
3. When the current is more than 250A, the wire dry elongation should be 20-25mm.
