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.

ISO 15614-1:2017 specifies how a preliminary welding procedure specification is qualified by welding procedure tests. ISO 15614-1:2017 applies to production welding, repair welding and build-up welding. ISO 15614-1:2017 defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the qualification of this document. The primary purpose of welding procedure qualification is to demonstrate that the joining process proposed for construction is capable of producing joints having the required mechanical properties for the intended application. Two levels of welding procedure tests are given in order to permit application to a wide range of welded fabrication. They are designated by levels 1 and 2. In level 2, the extent of testing is greater and the ranges of qualification are more restrictive than in level 1. Procedure tests carried out to level 2 automatically qualify for level 1 requirements, but not vice-versa. When no level is specified in a contract or application standard, all the requirements of level 2 apply. This document applies to the arc and gas welding of steels in all product forms and the arc welding of nickel and nickel alloys in all product forms. Arc and gas welding are covered by the following processes in accordance with ISO 4063. 111 - manual metal arc welding (metal-arc welding with covered electrode); 114 - self-shielded tubular-cored arc welding; 12 - submerged arc welding; 13 - gas-shielded metal arc welding; 14 - gas-shielded arc welding with non-consumable electrode; 15 - plasma arc welding; 311 - oxy-acetylene welding. The principles of this document may be applied to other fusion welding processes. NOTE A former process number does not require a new qualification test according to this document. Specification and qualification of welding procedures that were made in accordance with previous editions of this document may be used for any application for which the current edition is specified. In this case, the ranges of qualification of previous editions remain applicable. It is also possible to create a new WPQR (welding procedure qualification record) range of qualification according to this edition based on the existing qualified WPQR, provided the technical intent of the testing requirements of this document has been satisfied. Where additional tests have to be carried out to make the qualification technically equivalent, it is only necessary to perform the additional test on a test piece.

Its principles can also be applied to partial-penetration butt welds.(Quality levels for beam welded joints in steel are presented in ISO 13919‑1.) Three quality levels are given in order to permit application to a wide range of welded fabrication. They are designated by symbols B, C and D. Quality level B corresponds to the highest requirement on the finished weld. Several types of loads are considered, e.g. static load, thermal load, corrosion load, pressure load. Additional guidance on fatigue loads is given. The quality levels refer to production and good workmanship. ISO 5817:2014 is applicable to non-alloy and alloy steels, nickel and nickel alloys, titanium and titanium alloys, manual, mechanized and automatic welding,all welding positions, all types of welds (e.g. butt welds, fillet welds and branch connections), and the following welding processes and their sub-processes as defined in ISO 4063: 11 metal-arc welding without gas protection; 12 submerged-arc welding; 13 gas-shielded metal-arc welding; 14 gas-shielded arc welding with non-consumable tungsten electrodes; 15 plasma arc welding; 31 oxy-fuel gas welding (for steel only).

ISO 17663:2009 provides quality requirements for heat treatment in air or controlled atmospheres carried out in workshops and on site in connection with welding and forming. It applies mainly to ferritic steels, but can be used for other materials, as appropriate. ISO 17663:2009 provides guidance for manufacturers that perform heat treatment or produce heat-treated products or components. ISO 17663:2009 can also be used as a basis for assessing the manufacturer in respect to its heat treatment capability. ISO 17663:2009 is intended to be a flexible framework for the control of heat treatment processes. The fulfilment of a requirement can be waived where justification can be provided that a specific requirement is not applicable to a specific process.
