GB/T 32260.1-2015Destructive tests on welds in metallic materials -- Cold cracking tests for weldments -- Arc welding processes -- Part 1: General (English PDF)

Foreword

GB/T 32260 Destructive Tests on Welds in Metallic Materials – Cold Cracking Tests

for Weldments – Arc Welding Processes is divided into the following three parts.

--- Part 1. General;

--- Part 2. Self-Restraint Tests;

--- Part 3. Externally Load Tests.

This Part is Part 1 of GB/T 32260.

This Part was drafted as per the rules stipulated in GB/T 1.1-2009.

This Part uses redrafting method to modify ISO 17642-1.2004 Destructive Tests on

Welds in Metallic Materials – Cold Cracking Tests for Weldments – Arc Welding

Processes – Part 1. General.

Compared with ISO 17642-1.2004, this Part has the following technical differences

and their causes are as follows.

--- For the normative references, this Part makes adjustment against the technical

difference, so that adapt to China's technical conditions. The adjustment is

mainly reflected in Chapter 2 "Normative References", which is as follows.

Increase the GB/T 3375 Welding Terminology;

Replace partial international standards and European Standards quoted in

ISO 17642-1.2005 by China's corresponding standards.

This Part was proposed by and shall be under the jurisdiction of National

Standardization Technical Committee of Welding (SAC/TC 55).

Drafting organizations of this Part. Shanghai Institute of Special Equipment Inspection

& Technical Research, Harbin Welding Institute, Dongguan Qiancheng Laser

Technology Co., Ltd., China Special Equipment Inspection And Research Institute,

Tianjin Golden Bridge Welding Materials Group Co., Ltd., and China Petroleum

Natural Gas Pipeline Scientific Research Academy.

Drafting staffs of this Part. Xu Bin, Su Jinhua, Ou Xiaojun, Wang Kenan, Shi Kun,

Yang Yongmei, Sui Yongli, and Pu Dongguang.

Destructive Tests on Welds in Metallic Materials –
