About this detail

Weld access holes are detailed for structural steel framing members with specific geometrical constraints relative to flange thickness. Bevel angles and root openings are defined in accordance with American Welding Society standards for complete joint penetration welds. Minimum radii and longitudinal clearances are specified for both top and bottom flange transitions at column connections. Surface roughness limits and mandatory grinding requirements are noted for thermal-cut surfaces. Detailer must verify minimum edge distances between bolt holes and the weld access hole.
