1 Scope
This European Standard collects and classifies the possible imperfections in weldsmade with pressure. A uniform designation is specified. Only the type, shape anddimensions of the different imperfections caused by welding with pressure areincluded. Metallurgical deviations are not taken into account. Imperfections producedother than by the welding operation, for example additional stresses, loads orenvironmental factors are not covered by this standard.
Information concerning the consequences of the mentioned imperfections and the useof particular structures is not given because this depends on the specific requirementsof the joint.
2 Normative references
This European standard incorporates by dated or undated reference, provisions fromother publications. These normative references are cited at the appropriate places in thetext and the publications are listed hereafter. For dated references, subsequentamendments to or revisions of any of these publications apply to this European Standardonly when incorporated in it by amendment or revision. For undated references the latestedition of the publication referred to applies.
EN ISO 6520-1 Welding and allied processes - Classification of geometricimperfections in metallic materials - Part 1: Fusion welding(ISO 6520-1:1998)
3 Classification
The imperfections are classified into the following six groups:
P1 - CracksP2 - CavitiesP3 - Solid inclusionsP4 - Lack of fusionP5 - Imperfect shapeP6 - Any other imperfections not included in groups P1 to P5
The letter P stands for welding with pressure.
As regards Table 1 it has to be noted that:
a) column 1 gives a three figure reference number for each principal imperfection anda four or five figure number for each sub term;
b) column 2 gives the designation or name of each imperfection in English, Frenchand German;
c) columns 3 to 5 give the explanations in English, French and German wherenecessary;
