K-309LMT description:
Slag quantity is almost the same as a solid wire and deposition rate is up to 20% higher than a solid wire's one.
K-309LMT provides low spatter, excellent bead appearance and porosity resistance.
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 98%Ar+2%O2 for welding.
