Description
The ER347 2.4mm TIG Wire 5kg is a stainless steel filler rod designed for welding stabilized stainless steels such as 321 and 347. It includes niobium (columbium), which prevents carbide precipitation during welding. This feature improves corrosion resistance in high-temperature applications.
Welders use ER347 TIG wire when fabricating exhaust systems, heat exchangers, and pressure vessels. It performs well in environments where heat and corrosion resistance are essential. The niobium content makes it suitable for prolonged service temperatures above 427°C, especially when post-weld heat treatment isn’t possible.
This 2.4mm wire provides stable arc performance and smooth metal transfer. It allows precise weld control, resulting in a clean bead with minimal spatter. Whether you’re building piping, machinery, or industrial process equipment, you’ll get reliable, high-integrity welds with this rod.
Use DC+ polarity for best performance. The wire runs well on most TIG welding machines and is easy to work with—even in field repairs or shop settings. Its 5kg spool size offers a practical balance between volume and portability, making it ideal for maintenance crews, mobile welders, and small production runs.
Welders working in the food, petrochemical, and pharmaceutical sectors often choose ER347 TIG wire because it’s compatible with titanium- and niobium-stabilized base metals. It also prevents weld decay and cracking over time, ensuring long-term durability.
At Fourie Welding & Tool, we supply professional-grade welding consumables to help South African fabricators get clean, corrosion-resistant welds every time.
