GEN 308LSi is a stainless steel welding wire alloy for MIG welding. This wire is used to weld equipment made with 304 and 308 stainless grades.
GEN 308LSi Overview
GEN 308LSi has the same chemical composition as GEN 308, except the higher silicon content. It is suitable for welding stainless steel type 304 and 308. Welding process can be done at a higher speed than GEN 308 and GEN 308L due to improved wettability of weld metal. The higher silicon content also provides better arc stability along with smoother bead appearance.
