Prognosis of particulate emissions during laser material processing
Partikelgrößenverteilung gemessen während des Laserfügens von Polypropylen

The method provides a prognosis of the particulate emissions arising during the laser processing of a given material. Both, the absolute amounts of particles and the particle size distributions to be expected in industrial laser processes can be determined approximately. The results serve as a basis for workplace analyses according to TRGS 402 (German Technical Rule on Hazardous Substances no. 402) and emission characterizations according to TA Luft (German Technical Instructions on Air Quality Control).


For the prognosis, the total particle amounts are estimated and the particle size distributions are measured using an electrical low-pressure cascade impactor. For this purpose, a flat material sample is subjected to a basic laser process, such as cutting, welding or ablation.

A minimum of three material samples in the size of a DIN A4 page (German standard paper format, 21 cm (width) x 29.7 cm (height)) are required for the prognosis.
