Radiological abnormalities in electric-arc welders.
Chest radiographs of 661 British electric-arc welders have been examined by three film readers experienced in the radiology of pneumoconiosis. About 7% of the welders showed signs of small rounded opacities of category 0/1 or greater. No definite evidence of large opacities (Progressive Massive Fibrosis) was seen. The prevalence of chest abnormalities other than pneumoconiosis was 7%. A clear a...
متن کاملStainless steel manual metal arc welding fumes in rats.
Forty two male Wistar rats were exposed to manual metal arc (MMA) stainless steel (SS) welding fumes generated by an automatic welding device for "nose-only" exposure. The exposure simulated an actual MMA/SS welding environment as closely as possible. For the retention study, the duration of exposure was one hour per workday for one, two, three, of four weeks and for the clearance study four we...
متن کاملThe Study of Histopathological Effects of Electric Welding Fumes on Bronchiole and Lung of Rats
Purpose: The aim of the present study was to identify the quantitative and qualitative changes of bronchiole and lung alveoli in Rat after exposure to welding fumes. Materials and Methods: A total number of 60 male Sprague Dawley Rats were divided into two groups: imental (40) and control (20). Rats of each group were subdivided into 2, 4, 6 and 8 subgroups. Experimental Rats were exposed to w...
متن کاملModelling of Electrode-arc Coupling in Electric Arc Welding
Modelling of the arc in electric arc welding is significant to achieve a better process understanding, thus gain better weld quality and a more efficient production process. It requires knowing the conditions at the surfaces of the anode and cathode. These conditions are very difficult to set from measurements and should be calculated. This requires modelling the complex physics of the electrod...
متن کاملurinary β2 microglobulin in workers exposed to arc welding fumes
welding is a process in which two or more metals are attached by the use of heat and, in some cases, pressure. direct exposure and inhalation of welding fumes causes acute and chronic side effects in humans. kidney damage is one of these important side effects. β2 microglobulin is an 11.8 kilodalton protein and levels increase in the case of some inflammatory and viral diseases, or kidney malfu...
