BÖHLER NiCu 1-IG伯乐焊丝

BÖHLER NiCu 1-IG伯乐焊丝

Description
NiCu-alloyed copper coated GMAW wire, for welding of weathering resistant constructional
steels, standard constructional steels and special constructional steels.
NiCu 1-IG wire features good weldability 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.
