NF EN ISO 15610

ISO 15610:2003 gives the necessary information to explain the requirements referenced in ISO 15607 concerning the qualification of welding procedures based on tested consumables. In addition, it gives the range of qualification. ISO 15610:2003 applies to arc and gas welding but other fusion welding processes may be accepted if specified. It is limited to application to parent metals that produce acceptable micro structures and properties in the heat affected zone and which do not deteriorate significantly in service. This International Standard is not applicable where requirements for hardness or impact properties, preheating, controlled heat input, interpass temperature and post-weld heat-treatment are specified for the welded joint. The use of ISO 15610.2003 may also be restricted by an application standard or a specification.

This document specifies how a welding procedure can be qualified by using tested welding consumable data. It expands on the requirements given in ISO 15607. In addition, it gives the range of qualification. Application of this document is limited to parent material groups 1.1, 8.1, 21, 22.1 and 22.2 in accordance with ISO/TR 15608, which produce acceptable microstructures and properties in the heat-affected zone which do not deteriorate significantly in service. This document is limited to: —     butt welds and fillet welds in material of thicknesses t ≤ 40 mm (groups 1.1 and 8.1) and t ≤ 20 mm (groups 21, 22.1 and 22.2); —     fillet welds with throat thickness a ≥ 1 mm. This document is not applicable when any of the following is specified for the welded joint: a)       hardness; b)       impact properties; c)        preheating; d)       controlled heat input; e)       interpass temperature; f)         post-weld heat treatment. The use of this document can also be restricted by an application standard, specification or other documents.
