Lincoln LNT 309LSi welding rods, type ER309LSi / W 23 12 LSi, contain a higher amount of silicon, which improves the fluidity and wettability of the weld pool, ensuring smooth, regular welds. The alloy contains approximately 12% delta ferrite, which increases resistance to hot cracking. LNT 309LSi rods can also be used for welding coated steels operating at temperatures up to 300 °C. The main applications of the bars include general manufacturing and surfacing. The welding process takes place in an inert gas atmosphere, 100% argon.
