气焊、手工电弧焊及气体保护焊焊缝坡口的基本形式与尺寸
Application Summary AI generated
This standard specifies the basic forms and dimensions of weld grooves for gas welding, manual arc welding, and gas-shielded arc welding. It is applied in the manufacturing and fabrication industries to ensure consistent groove geometry for steel joints, guiding engineers and welders in preparing edges before welding. The standard is used in contexts such as structural steelwork, pressure vessel production, and general metal fabrication to achieve proper weld penetration and joint quality.
