Full title and description

ISO 22827-1:2005 — Acceptance tests for Nd:YAG laser beam welding machines — Machines with optical fibre delivery — Part 1: Laser assembly. This part specifies basic requirements and test methods for acceptance testing of high‑power (average power more than 100 W), lamp‑pumped or laser‑diode‑pumped Nd:YAG laser beam welding machines used for seam welding with optical‑fibre delivery systems, covering the beam generating system, the optical delivery system and devices for shielding and assist gases.

Abstract

Defines acceptance test procedures and minimum performance requirements for the laser assembly of high‑power Nd:YAG welding machines with optical‑fibre delivery, intended to verify output power/energy characteristics, beam delivery integrity and compatibility with shielding/assist gas arrangements prior to machine acceptance.

Scope

Applies to acceptance testing of high‑power Nd:YAG laser beam welding machines that use optical fibre delivery for seam welding; it is intended for the beam generator (lamp‑pumped or diode‑pumped), the optical delivery system and arrangements for shielding/assist gases. The standard is targeted at machines with average optical power above 100 W and may be used as part of commissioning, verification after major changes, or maintenance where re‑establishing acceptance data is required.

Key topics and requirements

• Acceptance test methods for laser output (power/energy stability and repeatability).
• Checks of optical‑fibre delivery integrity and alignment.
• Verification of compatibility and performance of shielding and assist gas devices.
• Requirements for test conditions, instrumentation and measurement procedures for acceptance testing.
• Guidance on when re‑testing is required after repairs or significant modifications.

Typical use and users

Manufacturers and suppliers of Nd:YAG laser welding machines, quality and acceptance engineers at end‑user production sites (automotive, aerospace, heavy fabrication), test laboratories performing commissioning and acceptance checks, and procurement/specification writers who require objective acceptance criteria for laser welding systems.

Related standards

ISO 22827 is issued in multiple parts; Part 2 (ISO 22827‑2:2005) covers acceptance tests for the moving mechanism (2D/limited Z motion) and defines mechanical positioning accuracy test methods that complement Part 1. In some regions this ISO series has been adopted as an EN/EN‑ISO publication (national adoptions exist).

FAQ

Q: What is this standard?

A: ISO 22827‑1:2005 is an international standard that sets out acceptance test requirements and methods for the laser assembly of high‑power Nd:YAG laser beam welding machines with optical‑fibre delivery.

Q: What does it cover?

A: It covers basic requirements and test procedures for the beam generating system (lamp‑pumped or diode‑pumped Nd:YAG), the optical delivery (fibre) system and devices for shielding/assist gases, focusing on machines with average optical power above 100 W used for seam welding.

Q: Who typically uses it?

A: Machine manufacturers, commissioning and quality engineers, test laboratories, buyers and specifications authors in sectors using laser seam welding (e.g., automotive, aerospace, heavy engineering).

Q: Is it current or superseded?

A: As published by ISO, ISO 22827‑1:2005 was last systematically reviewed and confirmed in 2020 and therefore remains the current edition (no superseding edition published to date).

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 22827 series (Part 2 addresses the moving mechanism and positioning tests). Several national and regional bodies have adopted the ISO parts as EN/EN‑ISO documents.

Q: What are the key keywords?

A: Nd:YAG, laser welding, acceptance test, optical fibre delivery, seam welding, laser assembly, shielding gas.
