ISO 15614-2:2005

Overview

ISO 15614-2:2005 - Specification and qualification of welding procedures for metallic materials - Part 2: Arc welding of aluminium and its alloys - defines how a preliminary welding procedure specification (pWPS) is qualified by welding procedure tests. It applies to the arc welding of wrought and cast aluminium and aluminium alloys, and covers the execution, examination and documentation of welding procedure tests for common arc processes (MIG, TIG and plasma). It does not cover finishing welding of aluminium castings (see Part 4).

Key topics and technical requirements

• Scope and applicability: Qualification of pWPS for fusion arc welding of aluminium; covers plates, pipes and typical joint geometries represented by standardized test pieces.
• Welding processes covered: EN ISO 4063 process numbers - 131 (MIG), 141 (TIG) and 15 (plasma).
• Preliminary WPS (pWPS): pWPS must be prepared per EN ISO 15609-1 and specify tolerances for relevant parameters.
• Test pieces (Clause 6): Defines shape, dimensions and number of test pieces required to permit all tests.
• Examination and testing (Clause 7): Specifies non‑destructive testing (NDT) and destructive tests required, locations of specimens (see figures and tables), acceptance levels, and rules for re‑testing.
• Range of qualification (Clause 8): Establishes how qualifications extend across manufacturers, parent materials, thicknesses, joint types and process‑specific variables.
• Qualification record (WPQR): Requirements for documenting results and producing a Welding Procedure Qualification Record (WPQR) that evidences successful qualification.
• Personnel qualification link: A welder who performs the welding procedure test satisfactorily may be qualified in accordance with EN ISO 9606-2 or ISO 14732, provided testing requirements are met.

Practical applications and end users

ISO 15614-2 is used by:

• Welding engineers and procedure developers preparing and qualifying pWPS/WPS for aluminium fabrication
• Fabricators and manufacturers of aluminium structures (plates, pipes, fittings)
• Quality assurance and inspection personnel performing NDT and destructive tests
• Certification bodies and testing laboratories issuing WPQRs
• Designers and project managers specifying qualification requirements for aluminium welding

Typical uses include qualifying new welding procedures, extending allowable ranges for thickness or materials, and documenting procedure capability for production welding of aluminium components.
