Filler wire is a critical component in welding processes, acting as the material that melts to join two metal surfaces. At Turnon Alloys, we provide high-grade Filler Wire Manufacturers solutions that meet the strictest industrial demands. Whether you're in aerospace, automotive, construction, or marine applications, our filler wires deliver optimal fusion and strength in every weld.

So, what is filler wire? It’s a consumable metal wire used in arc welding to fill the gap between metal joints. Filler wires melt during welding, combining with base metals to form a solid, high-strength joint. They’re engineered for precise chemistry, corrosion resistance, and mechanical properties, ensuring structural integrity in demanding environments.
The advantages of using filler wire are many. It offers better arc control, cleaner welds, reduced slag formation, and enhanced deposition rates. With consistent wire feed and metallurgical compatibility, it improves productivity and reduces post-weld clean-up. Turnon Alloys provides filler wires that meet international specifications, increasing reliability across all operations.
As one of the leading Filler Wire Suppliers, Turnon Alloys stocks an extensive inventory of stainless steel, nickel alloy, and duplex filler wires in multiple diameters and spool sizes. Every wire is tested and certified to ASME SFA 5.9, AWS A5.9, and ASTM A240 standards, ensuring conformity and traceability.
Globally, filler wires are known by different specifications. In the US, they're specified under AWS and ASTM codes. In Europe, EN ISO standards prevail. In Japan, JIS standards apply. Across the Gulf and Asia-Pacific, filler wires are commonly referred by their ASME or AWS numbers. Despite naming variations, the functional demand remains the same: precision, quality, and weld integrity.
At Turnon Alloys, we are not just Filler Wire Stockists; we are quality partners. Our inventory includes grades like ER308L, ER309L, ER316L, ER347, and more, suitable for MIG, TIG, and SAW welding.
