Beam impingement point adjustment
The precise adjustment of the cutting axes to the nozzle to ensure uniform cutting. Incorrect alignment leads to uneven flow and poor cut edges.
Physical-Chemical Mechanism of Action
The beam impact point adjustment ensures that the laser beam hits the material surface exactly. This affects the energy distribution and the cutting speed.
Metallurgical Relevance & Risks in Welding
An inaccurate adjustment can lead to one-sided flow losses, which processes the material unevenly. This increases the likelihood of cracks and poor cut edges. Furthermore, it can lead to incomplete refinement or excessive wear.
Workshop Practice & Instructions
Before starting the welding process, the adjustment of the axes must be carried out with an accuracy of at least 0.1 mm. This can be done with special measuring instruments and software tools. If the deviation is more than 0.2 mm, readjustment is required.
