Abstract
Modified metal transfers in MAG welding bring a number of advantages in terms of technology and operation. Likewise, it is possible to apply the same for cladding, where it is necessary to understand the influence of certain parameters. In this paper, the influence of the polarity balance of the AC MIG process on the geometrical characteristics and macrostructure during cladding of S355JR grade steel with 2205 duplex steel wire was investigated by producing three specimens with different current balances. Tests on the geometry of the welded layer as well as on the dilution rate were performed, and results indicating significant changes in geometry as a function of the change in polarity balance.
