Description:
CHT701
is a titania type flux
cored wire to be used with CO2 gas shielding. It makes higher deposition
rate than solid wires and also the welding performance and mechanical
properties of deposited metal are much better than solid wires. It is
suitable for flat or horizontal filler of thick or medial thick mild steel
structures and 490MPa high tensile steel structures such as ships,
machineries, chemical equipments, bridges and vehicles etc.
