1 Scope
This part of GB/12467 provides the criteria to be taken into account for the selection of the appropriate level of quality requirements for fusion welding of metallic materials.
This part is applicable to the welding manufacture in workshops and on site.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 19000 and the following apply.
3.1 Design specification
Requirements for products specified by customers (or by the organization in anticipation of customer requirements, or by regulation). The design specification may include the associated requirements, for example, technical specifications, product standards, process standards, contractual agreements and regulatory requirements.
NOTE The requirements for products and in some cases associated processes can be contained in, for example, technical specifications, product standards, process standards, contractual agreements and regulatory requirements.
3.2 Qualified person
Person whose competence and knowledge have been obtained by education, training and/or relevant practical experience
NOTE In order to demonstrate the level of competence and knowledge, a qualification test may be required.
3.3 Construction
Product, structure or any other welded item
3.4 Manufacturer fabricator
Person or organization responsible for the welding production
3.5 Sub-contractor
Supplier of products, services and/or activities to the manufacturer in a contractual situation
3.6 Welding operator
Person who performs fully mechanised or automatic fusion welding processes
4 General Outline of GB/T 12467
GB/T 12467 specifies quality requirements suitable for fusion welding processes of metallic materials. The requirements contained within this part may be adopted for other welding processes. These requirements relate only to those aspects of the quality of the products, which may be influenced by fusion welding, without being assigned to any specific product group.
GB/T 12467 therefore provides a method to demonstrate the capability of a manufacturer to produce products of the specified quality.
It was prepared such that:
a) It is independent of the type of construction manufactured;
b) It defines quality requirements for welding in workshops and/or on site;
c) It provides guidance for describing a manufacturer's capability to produce constructions to meet specified requirements;
d) It provides a basis for assessing a manufacturer's welding capability.
GB/T 12467 is appropriate when demonstration of a manufacturer's capability to produce welded constructions, fulfilling specified quality requirements, is specified in one or more of the following:
ˉa specification;
ˉa product standard;
ˉa regulatory requirement.
The requirements contained within this document may be adopted in full or may be selectively deleted by the manufacturer if not applicable to the construction concerned. They provide a flexible framework for the control of welding in the following applications.
ˉCase 1: To provide specific requirements in specifications which require the manufacturer to have a quality management system in accordance with GB/T 19001;
ˉCase 2: To provide specific requirements in specifications which require the manufacturer to have a quality management system other than GB/T 19001;
ˉCase 3: To provide specific guidance for a manufacturer developing a quality management system for fusion welding.
ˉCase 4: To provide detailed requirements for specifications, regulations or product standards that require control of fusion welding activities.
