Description and Applications |
|
HR80S-G is
a gas metal arc welding wire with Ar+CO2
shielding. Suitable for vertical down position welding
with large current supply or vertical up position
welding with low current supply and large heat input.
The bead produced have excellent tensile strength and
toughness, usually used for constructions, bridges,
ships pressure vessel, sea/ocean constructions and
welding of high tensile steel (550 N/mm2 and
above). |
