The Exocor ER309L TIG Welding Rod is a high-performance stainless steel filler metal designed for the Gas Tungsten Arc Welding (GTAW) process. This 0.035-inch diameter rod is engineered with a specific alloy composition—nominally 24% chromium and 13% nickel—making it the industry standard for joining dissimilar metals. It is most commonly used to weld Type 309 stainless steel to itself or to join 300-series stainless steels to carbon or low-alloy steels. The "L" designation indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process, thereby maintaining the corrosion resistance of the weld zone without the need for post-weld heat treatment.
Packaged in a convenient 10lb tube, these 36-inch cut lengths are cleaned and stamped to ensure traceability and ease of use. The higher alloy content of ER309L compared to ER308L provides excellent heat resistance and oxidation resistance at temperatures up to 2000°F (1093°C). This makes it an excellent choice for applying buffer layers or cladding carbon steel before capping with 308L or other stainless alloys. Industrial fabricators rely on Exocor's consistent quality to produce X-ray quality welds with superior bead aesthetics and mechanical integrity.
When precision and metallurgical reliability are paramount, the Exocor ER309L TIG rod delivers the performance professional welders demand. Its smooth feeding characteristics and stable arc control allow for precise puddle manipulation, essential for thin-gauge materials where a 0.035" diameter is utilized.
