Description
The ER309L 2.0mm TIG Wire 5kg is a high-quality stainless steel filler rod designed for TIG welding of dissimilar metals and stainless-to-carbon steel joints. This wire offers excellent crack resistance and corrosion protection, making it an excellent choice for structural and industrial applications where strength and reliability are critical.
Containing higher chromium and nickel content than 308L, ER309L TIG wire performs exceptionally well when joining stainless steel to mild or low-alloy steel. It also works effectively for buffer layers and for overlaying hard-facing applications. The low carbon content reduces the risk of carbide precipitation, helping maintain corrosion resistance in the heat-affected zone.
With a diameter of 2.0mm, this wire offers excellent control and precision. Welders often choose it for piping, structural steel, machinery repairs, and fabrication involving a combination of metal types. The 5kg pack size makes it perfect for smaller fabrication shops or projects that require high-quality welds without bulk waste.
You’ll get smooth arc stability, excellent wetting action, and minimal spatter during welding. Additionally, the wire provides consistent mechanical properties and clean bead appearance—ideal for critical applications.
For best results, use DC+ polarity and a clean work surface. Whether you’re welding stainless to carbon steel or using it as a buffer layer, ER309L delivers durable and reliable welds.
