New Viewpoint on Certifi cation Welding Materials from Position Reduce Hazard Level for Manufacturing Employees

Abstract

Welding is technical process characterized by clear rules about quality of welding unite and high level of health hazard. Mechanical strength of welding unite is provided by correct choice of type of electrode, but type of electrode never describe how welding process with this electrode will infl uence on health of welder. Many studies show that the dangers for health factor in welding process is welding fumes and especial solid particles, because they can stay lung in long time and infl uence as cumulative effect. Solid particles of welding fumes can consider like type of manufacturing dust.
