59446 - Avesta ER2209 Duplex Stainless TIG Rod 1/8" (3.2mm) - 10lb Box

Master Duplex Welding with Avesta ER2209

When the job calls for welding duplex stainless steel, you need a filler metal that you can trust to perform. The Avesta ER2209 TIG Rod in 1/8" (3.2mm) diameter is the professional's choice for joining 2205 grade stainless steels. Known for its smooth feeding and stable arc, this rod helps you lay down perfect beads with excellent wetting characteristics, making it easier to achieve that stack-of-dimes look even on challenging alloys.

Duplex stainless steel is notorious for being trickier to weld than standard 304 or 316, requiring careful heat management to maintain the correct ferrite-austenite balance. Avesta's ER2209 chemistry is optimized to help you get that balance right, providing a weld zone that is tough, ductile, and incredibly resistant to cracking. Whether you are repairing a chemical tank or fabricating high-pressure pipe, these rods give you the confidence that your welds will hold up against stress and corrosion.

Packaged in a convenient 10 lb (4.54 kg) box, these 3.2mm rods are ideal for heavier passes and filling grooves efficiently. The clean surface finish of the rods ensures excellent electrical conductivity and prevents contamination in the weld pool. If you are looking for a TIG rod that combines superior metallurgical performance with great playability under the hood, Avesta ER2209 is the way to go.
