The paper presents the application of MAG welding to TMCP steels (thermo-mechanically controlled processed) grade S960MC and 3 mm thick. In the analyzed joints, the research focused on their mechanical properties and changes in the heat-affected zone (HAZ) that occur in this type of steels. The hardness and tensile strength tests carried out showed a significant decrease in the properties of the joint compared to the declared values of the base material and the filler material used in the tests. In the case of hardness, it was a decrease of 34% in HAZ and by 15-21% in relation to the strength limit. Changes in HAZ properties of a joint correlate with changes in its structure.

W artykule przedstawiono zastosowanie spawania metodą MAG do stali z grupy TMCP (walcowanych termomechanicznie) o oznaczeniu S960MC i grubości 3 mm. W analizowanych złączach skupiono się na badaniach ich właściwości mechanicznych oraz zmian w strefie wpływu ciepła (SWC) jakie zachodzą w tego typu stalach. Przeprowadzone badania twardości i wytrzymałości na rozciąganie wykazały znaczny spadek właściwości w złączu w porównaniu z deklarowanymi wartościami materiału podstawowego oraz dodatkowym jakie zostały użyte w badaniach. W przypadku twardości był to spadek o 34% w SWC oraz o 15-21% w odniesieniu do granicy wytrzymałości. Zmiany właściwości w SWC złącza korelują ze zmianami zachodzącymi w jego strukturze.
