BS EN ISO 5817: 2007 Welding - Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded) - Quality levels for imperfections (ISO 5817: 2003, corrected version: 2005, including Technical CCorrigendum 1: 2006) (Eng)
This Standard was approved by CEN on 18 July 2007. 36p. This Inteational Standard provides quality levels of imperfections in fusion-welded joints (except for beam welding) in all types of steel, nickel, titanium and their alloys. It applies to material thickness above 0,5 mm. It covers fully penetrated butt welds and all fillet welds. The priciples of this Inteational Standard may also be applied to partial-penetration butt welds.
