What is ISO 15614 - Welding procedures for metallic materials about?
ISO 15614 on welding procedures for metallic materials provides preliminary welding procedure tests designed to ensure that a given weld will perform as required. This part covers arc and gas welding of steels and arc welding of nickel and nickel alloys. It defines how the welding procedure test should be conducted and the range of acceptable results.
Who is ISO 15614 - Welding procedures for metallic materials for?
ISO 15614 on welding procedures for metallic materials can be adopted by the fabrication and manufacturing industries, especially those with critical safety requirements, includes:
- Structural engineering
- Oil and gas
- Energy
- Nuclear
- Pressure vessels and equipment
- Chemical plant
- Shipbuilding
Why should you use ISO 15614 - Welding procedures for metallic materials?
Because it applies to production welding, repair welding, and build-up welding and specifies how a preliminary welding procedure specification is qualified by welding procedure tests. The main purpose is to demonstrate that the joining process proposed for construction is capable of producing joints having the required mechanical properties for the intended application.
Importantly, the ISO 15614 on welding procedures for metallic materials provides two levels of test so that it has a wide range of applications. Level 2 testing is much more extensive than Level 1 and the range of acceptable results is narrower. Procedure tests carried out to level 2 automatically qualify for level 1 requirements, but not vice-versa.
ISO 15614 on welding procedures for metallic materials 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 BS EN 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.
ISO 15614 on welding procedures for metallic materials also enables pressure vessel and pressure equipment manufacturers to conform to the essential requirements of Directive 2014/68/EU (PED) on pressure equipment and Directive 2014/29/EU (SPVD) on simple pressure vessels.
What’s changed since the last update?
BS EN ISO 15614-1:2017+A1:2019 has been amended. The main modification is the deletion of Clauses 8.5.2.3.2 to 8.5.2.3.4 regarding transfer mode.
