Before entering the market, coated electrodes, as an additional material in the MMAW welding process, must meet the existing regulations and requirements regarding the quality of welds, permissible harmful emissions into the environment and market requirements. In the MMAW welding process, welding fume is generated by the welding process. The emission level or production of welding fume, the method of collecting particles from welding fume and the method of chemical analysis are determined by the standard EN ISO 150011-1. The aim is to obtain a coated electrode with the lowest emission of harmful welding fumes into the environment and with the best welding characteristics. Tests of commercial and experimental electrodes of the same class were performed for the MMAW welding process of carbon and alloy steel. The production of welding fume particles was measured, and the welding fume particles were analyzed by the recommended methods of chemical analysis. These activities were fully carried out according to the standard EN ISO 150011-1.
