Full title and description

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. This document defines how a preliminary welding procedure specification (pWPS) is qualified by welding procedure tests and establishes requirements, test methods and ranges of qualification for production, repair and build-up welding of steels and of nickel and nickel alloys.

Abstract

ISO 15614-1:2017 specifies the conditions for execution of welding procedure tests and the ranges of qualification for welding procedures used in practical fabrication. Two test levels (level 1 and level 2) are defined to cover a wide range of welded fabrication applications; level 2 involves more extensive testing and stricter qualification ranges. The standard covers a set of arc and gas fusion welding processes (listed by ISO 4063 process numbers) and permits application of its principles to other fusion welding processes.

Scope

Applies to the arc and gas welding of steels in all product forms and to the arc welding of nickel and nickel alloys in all product forms; it is intended for production welding, repair welding and build-up welding. The standard defines requirements for performing welding procedure tests and for establishing the welding procedure qualification record (WPQR) and the resulting ranges of qualification for a welding procedure specification (WPS). Two qualification levels are provided (level 1 and level 2), with level 2 covering more extensive tests and narrower qualification ranges; where no level is specified, level 2 requirements apply by default.

Key topics and requirements

• Principles for qualification of welding procedures by welding procedure tests (WPQR/WPS creation and acceptance criteria).
• Two levels of welding procedure tests (level 1 and level 2) with defined scopes and relative test extensiveness.
• List of covered arc and gas welding processes (ISO 4063 codes such as 111, 114, 12, 13, 14, 15, 311) and allowance for application to other fusion processes.
• Mechanical and metallurgical testing requirements (tensile, bend, impact, hardness and macro/micro examination where applicable) and criteria for acceptance.
• Requirements for test piece preparation, welding parameters, preheat/interpass/post-heat treatments and ranges of qualification derived from the test results.
• Provision for reuse of previous WPQRs and for additional testing to extend or adapt qualification ranges to the 2017 edition when appropriate.
• Reference to amendment(s) (notably Amd 1:2019) which modify or clarify specific clauses (see amendment for details).

Typical use and users

Used by welding engineers, procedure writers, welding coordinators, fabricators, inspection and certification bodies, pressure equipment manufacturers, shipbuilders, the oil & gas and power industries, and testing laboratories. Typical applications include development and qualification of WPSs for manufacture, repair, refurbishment and construction where demonstrable mechanical properties and consistent welding process control are required.

Related standards

Related and commonly referenced documents include other parts of the ISO 15614 series (other materials/processes), ISO 4063 (welding process numbers), ISO 9606 (welder qualification), ISO 14731 (welding coordination), regional/adopted versions (e.g., EN ISO 15614-1) and comparable national codes such as ASME Section IX for procedure and welder qualification.

FAQ

Q: What is this standard?

A: ISO 15614-1:2017 is the international standard that specifies how welding procedures for metallic materials (specifically arc and gas welding of steels and arc welding of nickel and nickel alloys) are qualified by welding procedure tests and how ranges of qualification are established.

Q: What does it cover?

A: It covers the execution of welding procedure tests, required examinations and tests (mechanical and metallurgical), preparation of WPQRs/WPSs, and the ranges of qualification that result from the tests. Two test levels with differing extents of testing are defined.

Q: Who typically uses it?

A: Welding engineers, fabricators, testing laboratories, certification bodies, manufacturers of pressure equipment, shipbuilders and industries requiring formal procedure qualification for production and repair welding.

Q: Is it current or superseded?

A: The 2017 second edition is published and in force (corrected version issued 2017). An amendment (Amd 1:2019) is published to modify specific clauses; the ISO record indicates the document is subject to periodic review and replacement activity (a draft/discussion for a future revision has been recorded). Users should check national or official ISO records for the very latest status before relying on it for compliance.

Q: Is it part of a series?

A: Yes — ISO 15614 is a multi-part series addressing welding procedure tests and qualification for various materials and processes; Part 1 addresses steels (arc and gas) and nickel/ nickel alloys (arc). Other parts of ISO 15614 cover other materials and special processes.

Q: What are the key keywords?

A: Welding procedure test, WPQR, WPS, procedure qualification, steels, nickel alloys, arc welding, gas welding, ISO 4063, level 1, level 2.
