GB/T 9460-2023 Specifies copper and copper alloy welding wires. The standard specifies the applicable categories of copper and copper alloy welding wires, specifies their classification and model preparation methods, and puts forward strict requirements on the chemical composition, dimensional deviation, Appearance mass, etc. of the welding wires. At the same time, the test methods and inspection rules of the welding wires are given. According to this standard, the mass of copper and copper alloy welding wires can be ensured, and reliable products can be provided for the welding industry to ensure the performance of welding joints. It is widely used in machinery manufacturing, electric power and other fields to help related industries improve welding mass and production efficiency.
