Characteristics and typical fields of application NiCu-alloyed copper coated GMAW wire, for welding of weather-resistant constructional steels, standard constructional steels and special constructional steels. NiCu 1-IG wire features good weld ability in the short arc mode at low voltage and in the spray arc process with high voltage. The mechanical properties of the weld deposit, the freedom of porosity and the bead appearance depend on the type of shielding gas used and on the other welding parameters. The copper content in the welding wire leads to increased resistance to atmospheric corrosion in the weld deposit. tianjin haihan
