GB/T 44840-2024Welding procedure qualification test for upset(resistance butt) and flash welding (English PDF)

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 is modified to adopt ISO 15614-13:2023 "Welding procedure specifications and qualification assessment for metallic materials – Welding procedure tests" Part 13: Resistance butt welding and flash butt welding.

The technical differences between this document and ISO 15614-13:2023 and their reasons are as follows.

To adapt to my country's technical conditions, the scope has been revised (see Chapter 1); -the normative reference GB/T 228.1 replaces ISO 6892-1 (see 6.2.2, 7.3.1); the normative reference GB/T 2651 replaces ISO 4136 (see 6.2.2); ISO 5137 is replaced by the normative reference GB/T 2653 (See 6.2.3, 7.3.2, 7.3.4); replace ISO 6520-2 (see Chapter 3) with the normative reference GB/T 6417.2;

The normative reference GB/T 8366 replaces ISO 669 (see Chapter 3); the normative reference GB/T 11345 replaces ISO 17640 (see 7.2.6); replace ISO 14732 (see Chapter 5) with the normative reference GB/T 19805; replace ISO 14732 (see Chapter 5) with the normative reference GB/T 19805 GB/T 19866 replaces ISO 15607 (see Chapter 3) with the normative reference GB/T 19867.5.

Replaced ISO 15609-5 (see Chapter 4, Chapter 9); replaced ISO 23277 with the normative reference GB/T 26953 (See 7.2.3); replace ISO 17639 with the normative reference GB/T 26955 (see 7.4...

GB/T 27552 replaces ISO 9015-2 (see 6.2.5, 7.5); GB/T 29711 is replaced by the normative reference ISO 23279 (see 7.2.6); ISO 11666 (see 7.2.6) is replaced by the normative reference GB/T 29712 to apply to our National technical requirements;

Deleted ISO 15620:2019 and adopted the form of direct reference to the diagram (see Figure 1). Deleted the "for example" in 7.2.1.

content;

Added GB/T 26951 (see 7.2.4), GB/T 26952 (see 7.2.4), GB/T 26954 (see 7.2.5) and GB/T 32259 (see 7.2.2) is cited for ease of application.

The following editorial changes have been made to this document.

The name of the standard is changed to "Welding procedure qualification test for resistance butt welding and flash butt welding";

Deleted the footnotes of clauses 6.2.4 and 7.3.3 of ISO 15614-13:2023.

ISO 4063:2023 is replaced by the informative reference GB/T 5185 (see Table A.2, Table A.3).
