Welding stainless steel dangers. For instance mild steel is mostly iron but it also contains manganese which has received a great deal of attention recently in terms of its effect on health. The health hazards associated with welding and allied processes come from exposure to fumes and gases heat noise radiation as well as repetetive stresses that can cause musculoskeletal injuries MSIs such as strains and sprains. Shielded metal arc welding SMAW.
The one thing that can give rise to carbide precipitation a condition prevalent among the 300 series austenitic stainless steel is when they are subjected to extremely high heat for an extended period. When welding stainless steel a chemical that is known as hexavalent chromium or Cr VI is released into the air. Whether absorbed through the skin or respiratory system the particles and fumes released by stainless steel can wreak havoc on the human body in a range of ways.

Welding fumes are a combination of various metals. This fact sheet discusses welding operations applicable OSHA standards and suggestions for protecting welders and. The welding process produces visible smoke that contains harmful metal fume and gas by-products.
With the current change in OSHAs Hexavalent Chromium standard to 5 micrograms per cubic meter the risk of exposing employees is not only real it can be potentially expensive. Breathing these fumes may cause metal fume fever with symptoms similar to that of the flu nausea dizziness aches and pains fever etc. Since stainless steel is very reflective in nature UV exposure is only magnified when welding these materials and extra skin and eye protection is critical.
Ultraviolet radiation can also be a concern when arc welding and result in the development of melanoma and other cancers. Increased cancer risk has been noted in occupations other than welding. Cr VI fume is highly toxic and can damage the eyes skin nose throat and lungs and is carcinogenic.
Stainless steel also contains iron as well as nickel and chromium. So it is advisable to maintain proper heat input when welding stainless steel and mild steel. Toxic fumes from molten metals.
Welding of Coated or Painted Stainless Steel When working with galvanized SS workers should be aware of zinc oxide fumes. Each compound may have different health effects. TIG welding can be safe if proper precautions are used.
Shield gases can displace oxygen. Chromium fume is created by welding or cutting on stainless steel or metals that are coated with a chromium material. The four most common dangers of welding stainless steel are.
Stainless steel Inconel Monel Hastelloy and other high-alloy materials welding rods and plated steel. The dangers of welding stainless steel that arise from poor safety practice can be acute and sometimes short term depending on exposure however many of them pose chronic and long term health risks. Welding stainless steel is not lethal in any way but it can cause painful and very permanent damage to a person.
With specific weld processes welding on stainless steel without adequate control measures can lead to exposure at least several times above the legal exposure limit. Exposure to toxic fumes generated during the welding process can lead to dermatitis respiratory irritation eye and other organ damage asthma pulmonary congestion and cancer. Recently I was visiting a fabrication studio and the employer told me that he was really concerned about his welders exposure to hex chrome.
The following are the most common types of welding processes. It is a highly toxic chemical that can cause damage to. UV light from the welding arc can damage eyes and skin.
