ISO 15610:2024 outlines the procedure for qualifying a welding process by utilizing data from tested welding consumables. It builds upon the requirements established in ISO 15607 and specifies the range of qualification.
This document applies to the welding processes listed in Table 1 and is limited to parent material groups 1.1, 8.1, 21, 22.1, and 22.2 as defined in ISO/TR 15608. These materials must produce acceptable microstructures and properties in the heat-affected zone that do not significantly deteriorate during service.
The scope of this document is restricted to:
- Butt welds and fillet welds in materials with thicknesses of t ≤ 40 mm (for groups 1.1 and 8.1) and t ≤ 20 mm (for groups 21, 22.1, and 22.2);
- Fillet welds with a throat thickness of a ≥ 1 mm.
This document does not apply when any of the following conditions are specified for the welded joint:
a) Hardness;
b) Impact properties;
c) Preheating;
d) Controlled heat input.
