In buildings where welding is carried out, temperature control and problems of airborne contamination are important, and the provision of clean air increases. Although fresh air is usually supplied by general ventilation, the sole use of general ventilation for airborne pollutant control in welding is usually ineffective.
To extract welding fumes and protect the welder, at source ventilation is always the most efficient and safe way. In addition, all kinds of measures can be taken to reduce welding fumes and its risks.
Welding fumes contain oxides of the metals in the materials being welded. If not protected by personal protection equipment and proper ventilation measures, a welder and his surrounding are exposed to several health risks by the oxides of the metals.
Welding of stainless steel is a common process, which has increasing raised concerns for the working environment. Chromium is next to nickel one of the basic alloy element of all groups of stainless steels. During the welding process, chromium is converted to its hexavalent state, Chromium (VI).
Welding, glittering sparks and graceful curling fume are inseparable. It's almost a romantic image, with hard-working welders in the middle. However, the romance evaporates quickly if you understand what welding fumes are and what its composition may be.
