GB/T 19868.2-2005
ActiveWelding procedure qualification based on previous welding experience
基于焊接经验的工艺评定
Application Summary AI generated
This standard specifies the requirements for qualifying welding procedures by relying on documented previous welding experience, rather than conducting new destructive tests. It is applied in manufacturing industries, particularly for metal fabrication and structural welding, where a manufacturer has a proven history of producing sound welds under similar conditions. The standard is used to streamline qualification processes for repetitive or well-established welding tasks, ensuring consistency and reducing the need for redundant testing.
