Foreword

This Document was drafted as per the rules specified in GB/T 1.1-2020 Directives for

Standardization - Part 1: Rules for the Structure and Drafting of Standardizing Documents.

This Document replaced GB/T 2652-2008 Tensile Test Methods on Weld and Deposited Metal.

Compared with GB/T 2652-2008, the major technical changes of this Document are as follows

besides the structural adjustments and editorial modifications:

--- Change the requirements of "Scope" (see Clause 1 of this Document, Clause 1 of the

2008 Edition);

--- Add the requirements for continuously increasing the test force (see Clause 5 of this

Edition);

--- Add marking requirements (see 6.2 of this Edition);

--- Change the processing requirements of "other metal materials" (see 6.4.3 of this Edition;

2008 Edition).

This Document equivalently adopts ISO 5178:2019 Destructive Tests on Welds in Metallic

Materials - Longitudinal Tensile Test on Weld Metal in Fusion Welded Joints.
