1 Application scope
This standard is formulated to:
make it independent of type of construction which is ready for welding
determine quality requirements for shop welding and field welding;
provide guide for expressing a manufacturer's ability of manufacturing welded construction that can satisfy specified provisions;
be used as foundation of evaluating welding ability of manufacturer.
When one or more of the following conditions is/are met, if it is required to display a manufacturer's ability for manufacturing welded construction and satisfying specified quality requirements, this standard can be used for:
contract of the parties concerned;
applied standard;
general requirement.
These requirements of this standard can be entirely adopted by manufacturer. It can be selectively deleted when it is not applicable to concerned structure. These requirements provide welding control with applicable frame under the following conditions:

Provide special requirements to fusion welding of contract (contract requires manufacturer having quality system accords with GB/T 19001 or GB/T 19002).
Condition 2
Provide fusion welding in contract with special requirements (contract requires manufacturer having quality system different from GB/T 19001 or GB/T 19002).
Condition 3
Provide fusion welding with special requirements as a guide for manufacturer to establish a quality system.
Condition 4
Provide special requirements for applied standard or reference in contract of the parties concerned. However, this situation may be fit for using standard GB/T12467.3 or GB/T 12467.4.
