Welding Emissions - California Air Resources Board

May 19, 2011 · Emissions from stainless steel welding are a source of concern because of the potential health impacts from hexavalent chromium. In 2001 the Air Resources Board (ARB) identified hexavalent chromium (Cr+6) emissions from welding as a pollutant of concern and contracted with Dr. Dan Chang (UC Davis) to investigate and improve upon existing ...


The emissions from these dry processes are metal oxides which are similar in particle size to those generated in welding processes. The thickness of the material being cut, the cutting time per piece, and the hours of operation affect pollutant generation and loading.
