Kobelco - TGX - 316L x 2.2

Kobelco TG-X316L is a premium, flux-cored TIG welding rod engineered specifically for non-purging root pass welding.
It conforms precisely to the international classification AWS A5.22 R316LT1-5.

Like the rest of the TG-X family, it contains an internal flux formulation that creates a protective slag shield over the back of the root bead, eliminating the need for expensive back shielding gas (Argon purging).

Key Specifications & Applications
Target Materials: Formulated for joining low-carbon 18%Cr–12%Ni–2%Mo austenitic stainless steels, specifically AISI 316 and 316L. It is highly compatible with marine, food-grade, pharmaceutical, and chemical-processing plant materials.
Chemical Profile: Enhanced with 2.0% to 3.0% Molybdenum (Mo). This provides superior localized resistance to pitting, crevice corrosion, and acidic chloride media compared to 308L variants.

The No-Purge Advantage: Maximizes efficiency during field construction by removing the setup time needed for purging jigs or damming systems.
Welding Parameters: Requires Gas Tungsten Arc Welding (GTAW / TIG) on Direct Current Electrode Negative (DCEN) polarity using a 100% Argon torch shielding gas.

Critical Operating Procedures
Root Pass Only: Slag-generating characteristics restrict this rod exclusively to the initial root pass. It cannot be utilized to fill or cap subsequent weld layers.
Travel Speed Control: Conventional solid wire manipulation cannot be applied here. The welder must advance the rod quickly with a short-pitch travel technique. Sluggish movement traps molten slag inside the pool, creating immediate weld defects.
