Arc-welded joints in steel - Guidance on quality levels for imperfections (ISO 5817:1992)

This International Standard provides guidance on levels of imperfections in arc-welded joints in steel. Three levels are given in such a way as to permit application for a wide range of welded fabrications. The levels refer to production quality and not to the fitness-for-purpose (see 3.1) of the product manufactured.  This International Standard applies to:  -  unalloyed and alloyed steels; -  the following welding processes and their defined sub-processes in accordance with ISO 4063:   11  metal-arc welding without gas protection;  12  submerged-arc welding;  13  gas-shielded metal-arc welding;  14  gas-shielded welding with non-consumable electrode;  15 plasma arc welding;  -  manual, mechanized and automatic processes; - all welding positions; - butt welds, fillet welds and branch connections; - materials in the thickness range 3 mm to 63 mm.  When significant deviations from the joint geometries and dimensions described  in this International Standard are present in the welded product, it is necessary to evaluate to what extent the provisions of this standard can apply.   Metallurgical aspects, e.g. grain size, hardness, are not covered by this International Standard.

Lichtbogenschweißverbindungen an Stahl - Richtlinie für Bewertungsgruppen für Unregelmäßigkeiten (ISO 5817:1992)

Diese Internationale Norm ist eine Richtlinie für Bewertungsgruppen von Unregelmässigkeiten in lichtbogengeschweissten Verbindungen an Stahl. Die drei Bewertungsgruppen sind so festgelegt, dass sie eine breite Anwendung in der schweisstechnischen Fertigung erlauben. Die Bewertungsgruppen beziehen sich auf die Fertigungsqualität und nicht auf die Gebrauchstauglichkeit (siehe 4.1.1) der gefertigten Erzeugnisse.

Assemblages en acier soudé à l'arc - Guide des niveaux d'acceptation des défauts (ISO 5817:1992)

La présente norme internationale constitue un guide d'évaluation des niveaux des défauts dans les assemblages en acier soudés à l'arc. Elle prévoit trois niveaux de façon à être applicables à une large gamme de fabrication mécano-soudées.  Ces niveaux se rapportent à la qualité au sortir de l'atelier et non à l'aptitude à l'emploi du produit (voir paragraphe 4.1.1).
