This document specifies requirements for the qualification of welders and welding operators for fusion welding of metallic materials for aerospace applications. NOTE Success in the test is an essential precondition for the qualification of welders and welding operators in new production and repair work in aerospace. However, welding equipment operators do not need to be qualified according to this document.

Overview

ISO 24394:2023 - Welding for aerospace applications - Qualification test for welders and welding operators - Fusion welding of metallic components - defines minimum requirements for qualifying personnel who perform fusion welding on metallic aerospace hardware. The third edition (2023) is a prescriptive test standard used to demonstrate that a welder or welding operator has the necessary practical skill and theoretical knowledge for new production and repair work in aerospace. Note: welding equipment operators who only run automatic equipment and have no direct influence on joint quality are not required to be qualified under this document.

Key topics and technical requirements

Scope of qualification: Covers welder and welding operator tests for fusion welding of metallic materials used in aerospace.

Test structure:

Practical (hands-on) qualification tests and a theory exam.
Test piece selection based on parent material form, joint type (butt/groove, fillet), welding process, material group, thickness ranges and welding positions.
Welding coordinator/fabricator selects appropriate test piece(s); special test pieces and complementary tests are included.

Welding operator classification: Based on welding process and machine type (e.g., longitudinal, orbital, circumferential, robotic) - additional machine-type qualifications may be required.

Examinations and NDT: Visual inspection, dimensional checks, surface imperfection detection, radiographic examination, metallographic tests, bend tests and fracture-surface examinations.

Documentation and compliance: Test record, acceptance criteria, qualification certificate, period of validity and requalification requirements are specified. Annexes provide templates and guidance (test-piece acceptance criteria, test records, certificate examples, theory-test guidelines).

Related control documents: Uses terms such as WPS (welding procedure specification) and pWPS; aligns with welding coordination and NDT competency standards.

Practical applications and users

Who uses ISO 24394:2023:

Aerospace manufacturers, maintenance, repair and overhaul (MRO) organizations.

Welding coordinators, quality managers, and production engineers responsible for personnel qualification.

Training bodies and examining bodies that administer welder/welding-operator tests. Practical benefits:

Ensures consistently qualified welding personnel for critical aerospace structures.

Standardizes qualification across production and repair environments, improving traceability and airworthiness compliance.

Provides objective acceptance criteria and documentation for audits and regulatory review.
