foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules for Standardization Documents"

drafting.

This document replaces GB/T 10044-2006 "Cast Iron Electrodes and Wires". Compared with GB/T 10044-2006, except for structural adjustments and

In addition to editorial changes, the main technical changes are as follows.

a) Changed the classification principle and model compilation method of cast iron electrodes and welding wires. According to the homogeneity or heterogeneity of the weld metal and the

Classification by alloy type or chemical composition (see Chapter 4, Chapter 3 of the.2006 edition);

b) The dimensions of the clamping end of the electrode, the strength of the electrode coating and the moisture absorption resistance requirements are deleted, and the corresponding content is in accordance with the provisions of GB/T 25775 (see

4.1.1, 4.2.3 and 4.2.4 of the.2006 edition);

c) Added alloy type classification or chemical composition classification (see Chapter 4, 5.3, Chapter 3, 4.6 of the.2006 edition);

d) Changed the chemical composition requirements (see 5.3, 4.6 of the.2006 edition);

e) The technical requirements and test methods for the mechanical properties of welding electrodes and welding wire deposited metals with heterogeneous welds are added for use by agreement (see 5.5

and 6.5);

f) Changed the sample preparation and sampling requirements for the analysis of the chemical composition of the deposited metal for electrodes and flux-cored wires (see 6.3.1,.2006 edition

5.1.1, 5.1.2).

This document is modified to adopt ISO 1071.2015 "Welding consumables Welding rods, solid wires, filler wires and flux-cored wires for cast iron fusion welding

Classification".

Compared with ISO 1071.2015, this document has more structural adjustments. For a list of structure number changes between the two documents, see

Appendix A;

Compared with ISO 1071.2015, this document has more technical differences, and vertical single

Lines (|) are marked. See Appendix B for a list of these technical differences and their causes.

The following editorial changes have been made to this document.

--- In order to coordinate with existing standards, change the name of the standard to "Cast Iron Electrodes and Wires";

--- Added Appendix D (informative) "Contrast of Electrodes and Wire Models".
