GB/T 19868.4-2005
ActiveWelding procedure qualification based on pre-production welding test
基于预生产焊接试验的工艺评定
Application Summary AI generated
This standard specifies the requirements for qualifying welding procedures by conducting welding tests on actual production components or representative test pieces under pre-production conditions. It is applied in manufacturing industries, such as pressure vessel, pipeline, and structural steel fabrication, to validate that a welding procedure will produce sound welds before full-scale production begins. The standard is used by engineers and quality assurance personnel to ensure weld quality and process reliability in high-integrity applications.
