Struktura metala šava i zuta dobijena sa punjenom žicom MAG postupkom

The results of microstructure investigation of weld metal and HAZ of welded joints obtained when using cored wire AW10 and alloyed solid wire in CO2 shielding gas are presented in this paper. The effects of the welding regime and filler composition on the structure of weld metal and HAZ of high strength micro alloyed steel were studied in order to evaluate the advantages of using cored wire comparing to solid wire.
