GB/T 12470-2003
AbolishedLow-alloy steel electrodes and fluxes for submerged arc welding
埋弧焊用低合金钢焊丝和焊剂
Application Summary AI generated
This standard specifies the classification, technical requirements, test methods, and inspection rules for low-alloy steel welding wires and fluxes used in submerged arc welding. It is applied in the manufacturing and fabrication of pressure vessels, steel structures, and heavy machinery where high-strength or low-temperature service welds are required. The standard ensures consistent weld metal mechanical properties and chemical composition in automated or semi-automated welding processes.
