Acceptance tests for Nd:YAG laser beam welding machines. Machines with optical fibre delivery - Laser assembly1 Scope This part of ISO 22827 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 for seam welding with optical fibre delivery systems. The requirements can also be applied as a part of verification testing as part of maintenance, as appropriate. If modifications are made to a laser beam machine (rebuilding, repairs,
