A new chromium-free, nickel alloy invented by Ohio State University engineers gives welding professionals a safer option when doing their job.
According to the press release, the alloy is a welding “consumable” – the material that melts under the welder’s torch to fill the gap between parts that are being joined. It is more expensive compared to other alloys on the market, but it promises to lessen welders' risk of breathing toxic fumes in tight spots with less-than-ideal ventilation.
When the new alloy melts, it does not release hexavalent chromium into the air.
Toxic fumes a problem in welding profession
The Occupational Safety and Health Administration sets limits on workers’ exposure to hexavalent chromium in welding fumes, which affect welders themselves and their surrounding coworkers. Reduced exposure to such toxic fumes requires either extreme ventilation or use of a chromium-free consumable.
The Center to Protect Workers’ Rights has warned that stainless steel contains nickel and chromium, which can cause asthma. Nickel and chromium 6 can cause cancer, while chromium can cause sinus problems and “holes” between the nostrils.
Electrocorp has developed a series of effective source-capture air purification systems, including the Fume Extractor series and SafeSolder series, to help remove toxic fumes from the welders' environment.
