The article presents the results of tests aimed to assess the effect of the gas-shielded metal arc welding of protectively coated sheets on the emission of welding fumes (CO, NOx). The tests made it possible to identify the correlation between the welding method, protective coating type, current parameters and filler metals and the emission of pollutants. The tests involved the MAG, CMT, ColdArc and AC MIG Pulse welding of steel sheets provided with various protective (anticorrosive) coatings. The filler metals used in the tests were solid wire grade G3Si1 having a diameter of 1.2 mm and metallic flux-cored wire grade T3T Z M M 1 H15 having a diameter of 1.2 mm.
