1. Subject content and application scope This standard specifies the type classification, technical requirements, test method and test rules of carbon steel covered electrode. This Standard is applicable to carbon steel covered electrode for covered rod arc welding. 2. Normative References GB 700 Carbon Structural Steel GB/T 1591 Low-alloy High-tensile Structural Steel GB 223 1-223 24 Chemical Analysis Method for Steel and Alloy GB 2651 Tensile Test Method on Welded Joints GB 2652 Tensile Test Methods on Weld and Deposited Metal GB 2650 Impact Test Methods on Welded Joints GB 2653 Methods of Bend and Compression Tests for Welded Joint GB 3323 Methods for Radiographic Inspection and Classification of Radiographs for Fusion Welded Butt Joints in Steel GB/T 3965 Methods for Determination of Diffusible Hydrogen in Deposited Metal 3. Classification 3.1 Electrode type is classified according to mechanical properties of deposited metal, coating type, welding position and welding current categories (see Table 1). 3.2 Electrode type establishment method is as follows: letter "E" denotes electrode, the former two figures denote the minimum value for tensile strength of deposited metal, the third figure denotes welding position of the electrode, "0" and "1" denote that the electrode is applicable to all-position welding (flat, vertical, overhead and horizontal), "2" denotes that the electrode is applicable to flat welding and flat fillet weld, "4" denotes that the electrode is applicable to vertical down welding, the third and fourth figures combination denotes welding current category and coating type. Affix "R" at back of the fourth figure denotes moisture absorption proof electrode, affix "M" denotes electrodes with special regulations on moisture absorption proof and mechanical properties, affix "-1" denotes electrode with special regulations on impact property.
