Do you have information that supports lead and mercury poisoning can be caused from exposure to welding applications? The welding process in question are Shielded Metal arc welding (using coated electrodes) FCAW = flux cored arc welding ..same question. Inhaling fumes from these welding process over a period of time (years) any information supporting these questions or related illness from welding applications would be helpful. Byron Baudo |

ANSWER: 20 Jul 2006 Dear Byron, I'm sorry for the late reply. Welding process on lead-containing products can produce lead dust and fumes. You may want to check these links www.cdc.gov/niosh/91-116.html www.worksafe.wa.gov.au/newsite/worksafe/pages/manutool0004.html http://en.wikipedia.org/wiki/Shielded_metal_arc_welding www.kglg.com/case/case.asp?lngCaseId=1593 www.mist-dust-collection.com/fume-extraction/Welding-gases.pdf www.csao.org/UploadFiles/M029/Tools_and_Techniques/Welding_and_Cutting.pdf Shielded Metal arc welding is a common way of welding and this process can produce lead dust and fumes when it is done on lead-coated products. Therefore, good ventilation is needed to reduce the risk of lead poisoning. FCAW which is less commonly used can also produce lead-containing gas. If you are involved in welding for a long period of time and you are worried of lead poisoning, I advise you to have a blood lead test.
