Beam divergence compensation
Beam divergence compensation corrects the natural spreading of laser or plasma beams in thick plates to avoid geometry errors. It evens out the beam over the cutting depth.
Physical-Chemical Mechanism of Action
The natural divergence of laser or plasma beams causes the beam to widen with increasing depth. This can lead to uneven welding and geometry errors in thick plates.
Metallurgical Relevance & Risks in Welding
Without compensation, the uneven beam intensities can lead to different welding processes, stress formations, and potential cracks. This can impair the overall quality of the weld seam.
Workshop Practice & Instructions
Use beam divergence compensation for thick plates or complex geometries. Focus on even beam distribution across the entire cut depth. The exact setting depends on the machine and material used, but generally, compensation should be activated and adjusted accordingly to ensure optimal weld quality.
