Manganese steel, containing over 10% manganese, offers exceptional mechanical properties and is used in various high-durability applications. However, welding manganese steel generates fumes consisting of manganese, iron, chromium, and nickel, posing significant health risks such as manganism and respiratory diseases. Recognizing these hazards, strict regulations are necessary. This study analyzed manganese steel fumes for compliance with safety standards and compared them with carbon steel welding fumes. Manual welding of carbon steel produced fumes with manganese levels within permissible limits, unlike automatic welding which showed different fume patterns. Manganese steel welding generated fumes with manganese content compared to carbon steel. Using dust collectors and fume extraction torches reduced manganese levels below permissible limits. At 220mm and 440mm from the welding torch, both carbon steel and manganese steel welding met permissible exposure limits when using fume extraction devices.
