BS EN ISO 5817:2014,Welding – Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded) – Quality levels for imperfections.
This standard should be used as a reference in the drafting of application codes and/or other application standards. It contains a simplified selection of fusion weld imperfections based on the designations given in ISO 6520-1.
The purpose of this standard is to define dimensions of typical imperfections which might be expected in normal fabrication. It may be used within a quality system for the production of welded joints. It provides three sets of dimensional values from which a selection can be made for a particularapplication. The quality level necessary in each case should be defined by the application standard orthe responsible designer in conjunction with the manufacturer, user and/or other parties concerned.
BS EN ISO 5817:2014 provides quality levels of imperfections in fusion-welded joints (except
for beam welding) in all types of steel, nickel, titanium and their alloys.
