EX309L-030T - Exocor Executive ER309L Stainless TIG Rod - 0.030 Inch

Precision Stainless Steel Joining Solution

The Exocor Executive ER309L TIG Rod in 0.030" diameter is a specialized filler metal designed for high-integrity welding applications. Manufactured to meet stringent AWS A5.9 specifications, this rod features a nominal composition of 24% chromium and 13% nickel. This chemistry provides superior heat and corrosion resistance compared to standard 304/308 grades. The 'L' designation indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process, thereby maintaining corrosion resistance in the heat-affected zone (HAZ).

This specific diameter (0.030") is tailored for precision GTAW (TIG) processes involving thin-gauge base materials or intricate root passes where control is paramount. It is the preferred choice for cladding stainless steel over carbon or low-alloy steels, serving as an effective buffer layer. Additionally, it excels in joining dissimilar metals, such as welding 300-series stainless steels to mild or low-alloy steels, ensuring a ductile and crack-resistant weld deposit. The alloy is also suitable for certain cryogenic applications, offering good toughness at lower temperatures.

Exocor's manufacturing process ensures a clean, consistent surface finish on the wire, promoting smooth feeding and a stable arc. This results in high-quality radiographic welds with excellent bead aesthetics and minimal post-weld cleaning requirements.
