ActiveArc-welded joints in steel--Guidance on quality levels for imperfections
钢的弧焊接头 缺陷质量分级指南
Application Summary AI generated
This standard provides a classification system for imperfections in arc-welded steel joints, defining three quality levels (B, C, D) to guide acceptance criteria. It is applied in manufacturing and construction industries for quality control of welded steel structures, such as pressure vessels, bridges, and building frameworks, during inspection and testing. The standard helps engineers and procurement professionals specify acceptable weld quality for different service conditions and load requirements.
