Setup of a UV emission measurement system for manual laser beam welding processes and execution of extensive quantitative measurements for the user’s risk assessement

Project No. FF-FP 0439

Status:

ongoing

Aims:

Detection and rating of the emission of potentially hazardous incoherent ultraviolet (UV) and visible (VIS) secondary radiation incl. spectral characteristics at the workspace of manual laser beam welding; selection, verification and calibration of the measurement system; extensive data acquisition at real laser beam welding processes; practical description of the measurement routine and data handling for the cognition of risk potentials

Activities/Methods:

Configuration of a measurement system and verification at the manual laser working station; construction and assembly of a test setup; extensive quantitative measurements for the spatial acquisition of UV and VIS radiation during laser beam welding depending on laser and process parameters; measurement data analysis and creation of a base for the writing of risk assessements for industrial users by recommended actions
