1 Scope
This part of ISO 22827 covers acceptance testing of equipment for 2D manipulation and also, to some extent, movements along the Z-axis.
NOTE Welding robots and similar 3D equipment for manipulation are covered by other standards, notably ISO 9283.
This part of ISO 22827 specifies two methods for the testing of the accuracy of the moving mechanism. The first method (type 1 test) provides a test method capable of classification of the moving mechanism rigorously according to the required accuracy. The second method (type 2 test) provides a simpler method for testing the moving mechanism by marking. The selection of the test method is optional. However, for large-size laser beam welding machines, such as a laser beam welding machine using 2D moving optics or an X-Y table, the type 2 test is applicable.
This part of ISO 22827 is not applicable for welding cells with manual positioning of the welding head and/or the component, and for fixed-position welding without the moving mechanism.
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, modifications to the operating conditions, etc.) that have an effect on the acceptance testing, a repeat test may be necessary to cover the machine parameters affected by such modifications.
NOTE The beam generating system, the optical delivery system and the devices for shielding and assist gasses are covered in ISO 22827-1.
This part of ISO 22827 can be applied to a part of the acceptance conditions for the delivery of the laser beam welding machine.
