AK-ER55-D2
Standard:
GB/T 8110 ER55-D2
Description: AK-ER55-D2 is a CO2 gas shielded welding wire with H10Mn2SiMoA disc element and copper-plated surface. The welding wire can be gas shielded by CO2 or Ar-CO2, and the welding process is good.
Application: It is suitable for welding low-alloy high- strength steel structures with a tensile strength of 550MPa, such as vehicles, ships, bridges, pipelines, power stat-ions, and containers. Highrise buildings, petrochemicals, Chengong machinery, lifting and transportation equipment, boilers and pressure vessels, etc..
