适用范围：1.1 This standard prescribes the requirements of solid filler rods and wires for welding structural steels by inert gas tungsten arc welding (TIG), gas metal arc welding (MIG) or CO2 welding processes. The chemical composition of filler rods and wires is also specified.1.2 This standard does not specify the chemical composition and the mechanical properties of the weld deposit, because these will depend on the shielding gas and the particular welding conditions.1.3 Certain rods and wires specified in this standard are not suitable for use with particular shielding gas. Suitability of their use with a particular shielding gas should, therefore, be ascertained from the manufacturer while purchasing.
