Overview

SIST EN ISO 15616-4:2021 specifies the minimum requirements and practical test methods for acceptance testing of CO2-laser beam machines used for high quality welding and cutting with 2-D moving optics. The standard applies to machines where the workpiece remains fixed on the platen and the optics move in two dimensions, ensuring the machine's performance meets rigorous industrial demands. This part of the ISO 15616 series provides a structured approach to verify machine capability, focusing on accuracy and consistency during precision fabrication operations.

ISO 15616-4:2008 is not intended for CO2-laser beam systems with articulated robots, or those featuring integrated work stations (e.g., welding positioners or fixed board cutters). It also does not address hazard protection devices related to particle discharge.

Key Topics

Acceptance Test Conditions

• Requirements for basic installation, including vibration and temperature control
• Compliance of power supply, gas supply, and cooling systems with manufacturer specifications
• Provision of essential operational and safety instructions

Accuracy Verification Acceptance tests cover:

• Trajectory accuracy (tracking the programmed path)
• Straightness of motion along X and Y axes
• Squareness between X and Y movements
• Positioning accuracy in both axes
• Machining speed consistency

Test Preparation and Execution

• Verification of machine parts and measuring instruments
• Calibration requirements for measurement tools
• Standardized trajectory and straightness tests using marking instruments or controlled laser output

Test Reporting

• Detailed reporting format including model and serial numbers, test dates, test locations, responsible personnel, and calibration records

Applications

Practical Value in Manufacturing

• Quality Assurance: Ensures 2-D CO2-laser machines consistently produce precise welds and cuts, critical in industries such as automotive, aerospace, and fabrication.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15616-4 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 10, Unification of requirements in the field of metal welding.
This first edition of ISO 15616-4 cancels and replaces ISO/TS 17477:2003, which has been technically
revised.
ISO 15616 consists of the following parts, under the general title Acceptance tests for CO -laser beam
machines for high quality welding and cutting:
⎯ Part 1: General principles, acceptance conditions
⎯ Part 2: Measurement of static and dynamic accuracy
⎯ Part 3: Calibration of instruments for measurement of gas flow and pressure
⎯ Part 4: Machines with 2-D moving optics
Requests for official interpretations of any aspect of this part of ISO 15616 should be directed to the
Secretariat of ISO/TC 44/SC 10 via a national standards body, a complete listing which can be found at
