A study on the environmental and health impact of hazardous substances during welding

Abstract

Welding is a major joining process in modern manufacturing, primarily used for creating metal structures and components, as well as maintenance and repair operations. Welding, compared to other production processes, is regarded as a hazardous procedure that can have long-term detrimental consequences for persons and the environment. It's critical to be aware of these consequences and consider the possibility of employing environmentally friendly methods. Each welding process has distinct risks and pollutant exposures, thus choosing the proper technique for a given application with the lowest risk of hazards is critical. This article includes a technical and environmental overview of welding operations, as well as information on the major pollutants and their estimations. The effect of welding conditions, parameter optimization, operation, and materials on the formation of key contaminants is investigated and analyzed. The purpose of this study is to raise awareness of the dangers of welding contaminants to the environment and human health. It also suggests ways to mitigate these risks and promotes the development of green welding technology.
