Abstract


Electric arc welding is a manufacturing process that involves the existence of several factors with unfavorable effects on the environment. An analysis of the electric arc welding process allowed some clarification of the effects of polluting factors specific to this process. By using the systemic analysis method, the polluting effects generated by the electric arc welding process were highlighted. Considering the need for as much reasoned allocation of available financial resources to combat the polluting effects, the double-entry matrix method was used. In this way a somewhat justified ordering of the polluting effects became possible. It was found that the most intense polluting effect is determined by the number of harmful gases released, followed by visible radiation.
