ISO 15614-7:2016 specifies how a preliminary welding procedure specification for overlay welding is qualified by welding procedure tests.
ISO 15614-7:2016 defines the conditions for execution of welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the range of variables listed in Clause 8.
ISO 15614-7:2016 applies to all welding processes suitable for overlay welding. In situations where qualification is carried out on a pre-production test piece, the qualification is performed in accordance with ISO 15613 except that, as far as possible, the testing is according to this part of ISO 15614. Building up and repair of parent metal is covered by ISO 15613 or ISO 15614‑1.
This edition of ISO 15614‑7 is applicable to all new welding procedure qualification tests. It does not invalidate previous welding procedure tests made in accordance with previous editions of this part of ISO 15614. Where additional tests are required by the present edition, it is only necessary that those additional tests be carried out on a test piece made in accordance with the existing WPS and this part of ISO 15614.
If buttering is used for welding between dissimilar materials, the welding procedure is qualified in accordance with ISO 15614‑1. This buttering may be required for weld combining different material structure or properties, e.g. joining martensitic steels or ferritic steels with austenitic steels.
Additional tests may be required by application standards.

This document gives requirements and recommendations on levels of imperfections in electron and laser-beam welded joints in steel, nickel, titanium and their alloys. Three levels are given in such a way as to permit application for a wide range of welded fabrications. Quality level B corresponds to the highest requirement of the finished weld. 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:
—     steel, nickel, titanium and their alloys;
—     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.
The purpose of this document is to define the dimensions of typical imperfections which can be expected in normal fabrication. It can 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 particular application. The quality level necessary in each case is defined by the application standard or the responsible designer in conjunction with the manufacturer, user and/or other parties concerned. The quality level is expected to be prescribed prior to the start of production, preferably at the enquiry or order stage. For special purposes, additional details may need to be prescribed.
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.
Metallurgical aspects, e.g. grain size, hardness are not covered by this document.
This document does not address the methods used for the detection of imperfections. 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 additional requirements for inspection, examination and testing.

This European Standard complements EN 1708-1 with regard to applications in industrial, chemical and pharmaceutical sectors. It specifies established examples on how to construct claddings, linings and dissimilar joints and complex connections relevant to the welding technology and with regard to pressurized components (e.g. vessels, boilers and piping). In the following text therefore the term pressurized components will be used.
These examples can also be used for other applications provided the relevant requirements are taken into account. For exceptional cases such as specific problems concerning corrosion or materials in need of special processes, other solutions can be necessary which are to be agreed upon between purchaser and manufacturer.
Appropriate national regulations and corresponding design specifications are to be followed when selecting design examples as well as, if applicable, different or further requirements.
This European Standard does not override conditions on dimensioning of welded joints regarding strength (e.g.   according to EN 12952, EN 12953, EN 13445 and EN 13480). It is to be applied in accordance with the specified application limits for pressurized components subject to compression stress with bearing wall thicknesses  30 mm. This limit is chosen for structural reasons and not for the heat treatment that may be required. The wall thickness limit applies to butt welds in the bearing vessel wall only and does not apply to flanges, torispherical heads, flat ends or other similar parts.
This European Standard applies to the following types of steel:
- non alloyed steels with a minimum tensile strength of Rm  450 MPa;
- P295GH and 16Mo3 according to EN 10028-2;
- fine-grain steels according to EN 10028-3 with a minimum yield point ReL  355 MPa;
- austenitic steels according to EN 10028-7.
This European Standard can also be applied to other steels and/or larger wall thicknesses, provided that an agreement has been made between the manufacturer and the purchaser/operating authority.

The purpose of this European Standard is to exemplify commonly accepted welded connections in pressure systems. It does not promote the standardization of connections that may be regarded as mandatory or restrict development in any way. Stress analysis rules should be considered if necessary.
This standard contains examples of connections welded by:
-   Manual metal-arc welding with covered electrode (111);
-   Submerged arc welding (12);
-   Gas shielded metal arc welding (13);
-   Tungsten inert gas arc welding; TIG-welding (14);
-   Plasma arc welding (15)
processes (process numbers according to EN ISO 4063) in steel pressure systems. Other processes by agreement.
This standard covers welded joint details in steel, but can be applied to other metallic materials. In such cases the shape and dimensions of the weld should be checked.
The estimation of the suitability of welded connections for special service conditions, for example corrosion and fatigue are not specially considered.

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.
