This document gives guidance on levels of imperfections in electron and laser beam welded joints in
aluminium, magnesium and their alloys and pure copper. 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 of the product manufactured.
This document applies to electron and laser beam welding of:
— aluminium and its alloys;
— magnesium and its alloys;
— pure copper (e.g. Cu-ETP1 CW003A, Cu-ETP CW004A, Cu-FRHC CW005A, Cu-FRTP CW006A, Cu-OF1
CW007A, Cu-OF CW008A, Cu-OFE CW009A, Cu-PHC CW020A, Cu-HCP CW021A, Cu-PHCE CW022A,
Cu-DLP CW023A, Cu-DHP CW024A);
— all types of welds welded with or without additional filler wire;
— materials equal to or above 0,5 mm thickness for electron and laser beam welding.
When significant deviations from the joint geometries and dimensions stated in this document are
present in the welded product, it is necessary to evaluate to what extent the provisions of this document
can apply.
NOTE For circular welds, a lower quality level can be specified for the fade-out zone.
Metallurgical aspects, e.g. grain size, hardness, hydrogen embrittlement (pure copper) are not covered
by this document.
This document is directly applicable to visual examination of welds and does not include details of
recommended methods of detection or sizing by other non-destructive means. There are difficulties
in using these limits to establish appropriate criteria applicable to non-destructive testing methods,
such as ultrasonic, radiographic and penetrant testing, and they can need to be supplemented by
requirements for inspection, examination and testing.

1.1 This European Standard covers the grades of wrought steels and alloys listed in Table 1 and Table 2, which are usually employed for components and equipment, for which the main requirement is their creep resistance under mechanical long-time stressing at temperatures above 500 C.
NOTE Heat resisting grades given in EN 10095 [9] may also be used for similar applications if so agreed.
1.2 This European Standard specifies the technical delivery conditions for semi-finished products, for hot or cold rolled sheet/plate and strip, hot or cold formed (cold drawn) bars, rods, wire and sections.
1.3 The general technical delivery conditions specified in EN 10021:2006 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard.
1.4 This European Standard does not apply to components manufactured by further processing the product forms listed in 1.2 with quality characteristics altered as a result of such further processing.
1.5 This European Standard shall not be used for aerospace and pressure purposes.
1.6 For steels and alloys with similar chemical composition, but intended for different applications, see the Bibliography.

This Technical Report constitutes an attempt to explain the numerical results of a statistical examination in the simplest possible way and to show how statistical results can be used in laboratory practice. This simplified method is applicable when the number of laboratories is not more than 20 and when the number of results per laboratory is not more than 10.

This part of ISO 3134 defines relating to materials special terms to aluminium and aluminium alloys and general terms such as alloy, alloying element, impurity, wrought alloy, casting alloy, master alloy, heat-treatable alloy etc. Magnesium and magnesium alloys will be classified to a later time.

The designations of metals and alloys shall be based on the chemical composition limits given in International Standards. International chemical symbols shall be used for the designation of the principal metal and the major alloying elements followed by numbers indicating the metal grade or the nominal alloy content.
