Emission measurement
Gases and particles are emitted during the welding process. Most of these particles are metal oxides. These particles are one or two orders of magnitude smaller than the limit for particulate matter, which is set at 10 μm.
A smoke chamber compliant with DIN EN ISO 15011-1 is available for the quantification of emissions. The suction volume is 1 m³/min. The glass fiber filters we use have a diameter of 250 mm and an average retention capacity of 0.5 μm. The residues in this filter are quantified by differential weighing.
