Foreword

GB/T 25343 "Railway applications - welding rail vehicles and their components" is divided into five parts.

--- Part 1. General;

--- Part 2. Welding manufacturer's quality requirements and certification;

--- Part 3. Design requirements;

--- Part 4. Production requirements;

--- Part 5. Inspection, testing and documentation.

This section GB/T 25343 Part 1, corresponding to EN15085-1:2007 "Railway applications rail vehicles and their components Welding - Part 1. General. " The partial modification using EN15085-1:2007, the main changes are as follows.

1 Scope

This series of standards for the field of rail vehicle provides assume a new creation and maintenance of welding manufacturer's qualification and quality requirements.

Thus this series of standards to the design process performance requirements, the production process to achieve high-quality welds, as well as through show satisfaction Quality together.

This link is defined by security and by load factor determining the grade of weld quality in the design process and get. Quality defects the amount of grading and grade of weld quality is linked, in order to guarantee the achievement of the desired quality level design. According grade of weld quality, provides enterprise Authentication level, welding and weld inspection level qualification.

This series of standards applies to welding rail vehicles and parts manufacturing, and maintenance of metallic materials.

GB/T 25343 in this part of the welding rail vehicles and their components gives the definition of general recommendations and related terms. In addition to co with special provisions to the provisions of this section apply to all welding methods, including manual welding GB/T 5185 defined, semi-automatic welding, Fully mechanized welding or automatic welding.

This section applies to the welding of steel and aluminum, as well as casting welding.

Note. The principle of this section is also applicable to other materials (such as copper and magnesium) welding.

This series does not involve certification standard.

This series of standards do not apply to special regulations piece of equipment such as pressure vessels.
