Overview
ISO/TR 17671-6:2005 - "Welding - Recommendations for welding of metallic materials - Part 6: Laser beam welding" is an informative Technical Report from ISO that provides general guidance for laser beam welding of metallic materials in all forms (cast, wrought, extruded, forged) and for associated laser processes. It is intended as practical, non‑normative advice covering equipment, process characteristics, design, quality control and common detrimental phenomena. Annexes extend the guidance to beam properties, weldability of metals, causes of imperfections, beam control and auxiliary laser processes (cutting, drilling, cladding, surface treatment).
Key Topics
- Scope & purpose: General guidance for satisfactory production and control of laser beam welding and related processes; not prescriptive but informative for implementation and specification.
- Health, safety & environment: Safety considerations for laser processing and machinery (aligned with ISO safety norms).
- Quality requirements: Recommendations for quality systems and inspection levels appropriate to laser welding.
- Equipment: Acceptance testing, maintenance and calibration of laser sources, optics, manipulators, fixtures and cooling/control systems (see Annex A).
- Personnel qualification: Guidance on qualification and approval testing of welding operators and technicians.
- Welding procedure: Preparation of Welding Procedure Specifications (WPS) and welding procedure tests (WPT) for laser beam welding.
- Consumables & shielding: Notes on filler metals, shielding gases and related consumables.
- Design & joint preparation: Principles for overall product design, joint configuration and fit‑up to accommodate laser welding characteristics.
- Process control & inspection: Beam control, monitoring parameters, focal position, power distribution and inspection/testing methods (Annex E).
- Weldability & imperfections: Material‑specific weldability guidance (Annex C) and causes/prevention of imperfections (Annex D).
- Laser processing variants: Informative guidance on cutting, drilling, cladding and surface treatment (Annex F).
