63183200 - Bonarc 316L Stainless TIG Filler Rod 1/8" (3.2mm) - 5kg Tube

Master Your Stainless TIG Welds with Bonarc ER316L

Elevate your welding projects with the Bonarc ER316L TIG Welding Rods. This 5kg tube of 3.2mm (1/8") rods is designed for welders who demand precision, strength, and aesthetic perfection in their stainless steel fabrication. Whether you are a professional pipe welder or a skilled fabricator, the ER316L alloy provides the smooth running characteristics and puddle control necessary for producing X-ray quality welds.

Ideal for Critical Projects

When working with 316 or 316L stainless steel, matching the base metal is crucial. The Bonarc ER316L is formulated with Molybdenum to match the corrosion-resistant properties of the parent material. This makes it the go-to filler for projects exposed to harsh elements, such as marine hardware, brewery equipment, and pharmaceutical piping. The 3.2mm diameter is particularly effective for filling larger joints and welding thicker wall pipes or plates, allowing for efficient fill passes without sacrificing control.

Metallurgy Made Simple

The chemistry of this rod is designed to make your life easier. The extra low carbon content acts as a safeguard against intergranular corrosion, a common failure mode in stainless steel welds known as "weld decay." This means your welds will remain durable and rust-free even in the heat-affected zone. Additionally, the balanced composition promotes excellent wetting action, helping the molten pool tie into the toes of the weld smoothly, reducing the chance of undercut and cold lap.

Welding Tips for 3.2mm Rods

For best results with this 3.2mm rod, ensure your base material is meticulously cleaned of all oils and oxides. Use 100% Argon shielding gas to protect the molten pool and tungsten electrode. A DCEN (Direct Current Electrode Negative) setup is standard for TIG welding stainless steel. The larger diameter of this rod allows for higher amperage settings, typically ranging between 90 and 160 amps depending on the joint configuration and travel speed. Store your rods in the provided tube to keep them free from shop dust and moisture, ensuring every rod performs as well as the first.
