GB/T 39279-2020
ActiveWire electrodes, wires，rods and deposits for gas shielded arc welding of creep-resisting steels
气体保护电弧焊用热强钢实心焊丝
Application Summary AI generated
This standard specifies the classification, technical requirements, test methods, and inspection rules for solid wire electrodes, wires, rods, and their deposited metal used in gas shielded arc welding of creep-resisting steels. It is applied in the manufacturing and repair of high-temperature equipment, such as boilers, pressure vessels, and steam pipelines in power plants and petrochemical industries, where materials must withstand elevated temperatures and stress. The standard ensures weld quality and performance consistency for components operating under creep conditions.
