ISO 17927-2:2020 PDF

Scope: This document specifies acceptance criteria for fusion weldments on metallic components. It is to be applied provided it is referenced or approved by the responsible engineering/design authority. This document covers the following processes given in Table 1 and the material groups given in Table 2. Table 1 — Fusion welding processes covered by this document Process Process number (ISO 4063:2009) Oxyfuel welding 31 Gas shielded arc welding with non-consumable tungsten electrode, gas tungsten arc welding 14 Plasma arc welding 15 Electron beam welding 51 Laser welding, laser beam welding 52 Table 2 — Material groups covered by this document Material group Description A Unalloyed steel, low alloyed steels, high alloyed ferritic steels B Austenitic, martensitic and precipitation hardening steels C Titanium and titanium alloys, niobium, zirconium and other reactive metals D Aluminium and magnesium alloys E Materials that do not conform to other material groups (e.g. molybdenum, tungsten, cop- per alloys) F Nickel alloys, cobalt alloys. NOTE Material groups according to ISO 24394.
