GB/T 32533-2016Covered electrodes for manual metal arc welding of high-strength steels (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the re-drafting method to amend the use of ISO 18275.:2011 "welding materials high-strength steel electrode welding arc welding Class "(English version).

The main technical differences between this standard and ISO 18275.:2011 are as follows.

- to delete the normative reference documents cited in the international standards, direct reference to China has been the corresponding transformation of the relevant domestic standards;

--- model preparation using international standard preparation method, according to China's actual application, the heat treatment status code, the welding code from "A" is modified to "unmarked";

--- According to China's actual application needs, in the deposited metal tensile strength code, an increase of 73,88 and 98 three strength level;

--- According to China's practical application needs, in the chemical composition of the classification of metal classification code, an increase of N7CM1, 11MoVNi and 11MoVNiW and other categories;

--- According to China's actual application needs, an increase of E5915-3M2, E5915-N5M1, E5918-3M2, E6215-N2M1, E6215-N5M1, E7815-G and other electrode models;

--- increase the electrode eccentricity of the technical indicators.

For ease of use, this standard has also made the following editorial changes.

--- standard name changed to "high-strength steel electrode";

--- standard structure, according to the model, technical requirements, test methods, inspection rules, packaging, logo and quality certification to prepare.

This standard is proposed by the National Welding Standardization Technical Committee (SAC/TC55).
