K-309T description:
K-309T is a titania type of flux cored wire for cladding and dissimilar joint welds.
It is designed for operation in the flat position and for welding horizontal fillet welds.
Weld metals contain comparatively much more ferrite in their austenitic, therefore they provide better weldability together with superior heat resistance,and corrosion resistance.
The shielding gas should be used 100%CO2 and 80%Ar+20%CO2 for welding.
