Welding of stainless steel is a common process, which has increasing raised concerns for the working environment. Chromium is the basic alloy element of all groups of stainless steels. The majority of those steel grades contain nickel. During the welding process, chromium is converted to its hexavalent state, Cr(VI). The production of these elements occurring in stainless steel welding fume is believed to have serious effects on the health of welders and people in the welding environment. Cr(VI) fume is highly toxic and can damage the eyes, skin, nose, throat, and lungs and can cause cancer.

METHODS AND FUME PRODUCTION

The amounts of fumes released during the welding of stainless steel depend largely on the welding method used. The most common methods are:

• Tungsten Inert Gas (TIG)
• Metal Inert Gas (MIG)
  About 80% of welding operations use this method:

• Manual Metal Arc (MMA)
  and 5% specialist companies uses for specific applications:

• Flux Cored Arc (FCA)

TIG produces the least fume although it does produce significant amounts of ozone and nitrous oxide both of which are irritant gases. MIG and MAG generally produce quite a lot more fume. MMA welding and FCA tend to produce the most fumes.
