Foreword

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

Drafting.

This document is Part 3 of GB/T 46087 "Shop Primer Welding and Related Process Tests". GB/T 46087 has been published as follows.

Part 2.

---Workshop primer welding and related process tests, Part 1: General requirements;

---Workshop primer welding and related process tests, Part 2: Welding performance;

---Workshop primer welding and related process tests, Part 3: Thermal cutting;

---Workshop primer welding and related process tests, Part 4: Emission of smoke and gas.

This document is modified to adopt ISO 17652-3:2003.Welding shop - Primer welding and related processes - Tests - Part 3: Thermal cutting.

The technical differences between this document and ISO 17652-3:2003, and the reasons therefor, are as follows.

---The scope has been changed to conform to the drafting rules of Chinese standards (see Chapter 1);

---The normative reference GB/T 46087.1 replaces ISO 17652-1:2003 (see Chapter 3); the normative reference...

GB/T 700 replaced EN10025, and the normative reference GB/T 8923.1 replaced ISO 8501-1:1988.

GB/T 13452.2, a normative reference, replaces ISO 2808 (see 4.1); JB/T 10045, a normative reference, replaces [the previous standard].

EN ISO 9013 (see 4.2) is adopted to suit my country's technical requirements.

---Fiber lasers have been added to the laser types (see 4.6) to adapt to the domestic technological environment.

The following editorial changes have been made to this document.

---The standard title has been changed to "Shop Primer Welding and Related Process Tests Part 3: Thermal Cutting";

---Appendix ZA of the international standard has been deleted.

Introduction

Shop primer, as a key protective layer in steel pretreatment, is widely used in steel structures, shipbuilding, and automobile manufacturing, and its performance directly affects...

It relates to the quality and safety of subsequent processes such as welding and cutting.

GB/T 46087 "Shop Primer Welding and Related Process Tests" aims to establish a complete evaluation system for shop primer processes, including shop primer...

The impact of paint on welding performance, thermal cutting efficiency, and fume emissions is divided into the following four parts.

---Part 1: General Requirements. The purpose is to specify the basic conditions, terminology definitions, environmental and safety requirements for testing, in order to provide a basis for subsequent testing.

Provide a unified framework.

---Part 2: Weldability. The purpose is to assess the effect of shop primer on weldability by evaluating the severity of weld porosity defects.

The impact.

---Part 3: Thermal Cutting. The purpose is to clarify the test method for the maximum thermal cutting speed of the shop primer, using standardized test pieces.

Preparation and cutting parameters were set, and the impact of the primer on cutting efficiency and process stability was evaluated.

---Part 4: Emissions of Smoke and Gases. The aim is to establish an evaluation system for the emission levels of smoke and harmful gases from the primer workshop.

This system provides technical support for reducing occupational health hazards and environmental pollution.
