SN EN ISO 15614-1:2017 Welding Standards Explained
SN EN ISO 15614-1:2017
Anforderung und Qualifizierung von Schweissverfahren für metallische Werkstoffe - Schweissverfahrensprüfung - Teil 1: Lichtbogen- und Gasschweissen von Stählen und Lichtbogenschweissen von Nickel und Nickellegierungen (ISO 15614-1:2017)
Specification and qualification of welding procedures for metallic materials - Welding procedure test - Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys (ISO 15614-1:2017)
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. ISO 15614-1:2017 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.
The SN EN ISO 15614-1:2017 standard outlines requirements for qualifying welding procedures for metallic materials, focusing primarily on arc and gas welding of steels and arc welding of nickel and nickel alloys.
Purpose and objectives
The primary purpose of the SN EN ISO 15614-1:2017 standard is to establish a framework for the qualification of welding procedures. This ensures that the welding process is consistent, reliable, and produces welds that meet specific mechanical properties and performance criteria. By adhering to this standard, manufacturers can minimize risks associated with weld integrity, enhance safety, and comply with regulatory requirements, particularly within the pressure equipment and manufacturing sectors.
Scope: who must comply
The SN EN ISO 15614-1:2017 standard applies to organizations involved in the welding of metallic materials, particularly in industries such as construction, manufacturing, and repair services. Typical company profiles include manufacturers of pressure vessels, structural steel fabricators, and those working with nickel alloys. Compliance is essential for ensuring that welding procedures meet international safety and quality standards, particularly in contexts governed by the Pressure Equipment Directive (PED) and similar regulations.
How SN EN ISO 15614-1:2017 relates to other standards
The SN EN ISO 15614-1:2017 standard is closely associated with several other key standards:
- ISO 15614-2: This standard covers the qualification of welding procedures for non-alloyed and alloyed steels, complementing the requirements of SN EN ISO 15614-1:2017.
- EN ISO 4063:2011: This document provides a classification of welding processes, serving as a reference for the types of welding included in SN EN ISO 15614-1:2017.
- Directive UE 2014/68/UE: This directive outlines essential safety requirements for pressure equipment, reinforcing the importance of compliance with welding standards.
Revision history and current status
The SN EN ISO 15614-1:2017 standard was published by the Swiss Association for Standardization (SN) in 2017. This revision supersedes previous versions and incorporates updates that enhance clarity regarding the qualification of welding procedures, ensuring alignment with international practices. The current status highlights its acceptance as a vital framework for welding procedure qualification across various industries.
