OVERVIEW

Precision Stainless Welding with Bonarc 308L

When you are under the hood TIG welding stainless steel, consistency is everything. Bonarc ER308L TIG rods are designed to give you that buttery smooth feed and clean puddle control that professional fabricators demand. This 5kg tube of .045" rods is the perfect companion for precision work on thin-gauge materials. Whether you are fabricating commercial kitchen counters, welding exhaust tubing, or repairing food processing equipment, the .045" diameter allows for delicate puddle manipulation without dumping excessive filler metal into the joint.

The 'L' in 308L stands for Low Carbon, but for you, it stands for peace of mind. It means the weld you lay down today won't rust out from the inside tomorrow due to carbide precipitation. This rod flows wet and flat, tying into the toes of the weld effortlessly to create that stack-of-dimes look with minimal post-weld cleanup. The high-quality surface finish on every rod ensures you don't introduce contaminants into your weld pool, reducing the chance of porosity or inclusions that could fail an inspection.

Bonarc ER308L is the go-to filler for the most common stainless steel grades, specifically 304 and 304L. If you are working on general fabrication, architectural stainless, or sanitary piping, this is the rod you need in your quiver. It runs best on DCEN (Direct Current Electrode Negative) with 100% Argon shielding gas. The rods are stamped for easy identification, so you never have to guess what you are holding, even after the tube is opened. Grab a tube today and experience the difference a quality filler metal makes in your arc stability and final bead appearance.

FAQ

The 'L' stands for Low Carbon. ER308L has a maximum carbon content of 0.03%, which prevents carbide precipitation and intergranular corrosion, making it superior for corrosion resistance compared to standard ER308.

For TIG welding with ER308L, use 100% Argon gas. This ensures a stable arc and protects the molten weld pool from atmospheric contamination.

No, ER308L is designed for joining stainless to stainless (specifically 300 series). For welding mild steel to stainless steel, you should use an ER309L filler rod.

Generally, no. A .045" (1.14mm) rod is quite thin and is best suited for thin-gauge sheet metal (approx. 16-22 gauge). For thicker plate, you would typically use 1/16", 3/32", or 1/8" rods to get adequate deposition rates.

TIG welding with stainless steel rods like ER308L is performed using DCEN (Direct Current Electrode Negative), also known as Straight Polarity.

While it varies slightly by exact length and density, a 5kg tube of .045" stainless steel TIG rods contains a high quantity of rods, typically several hundred, due to the small diameter and light weight of each individual rod.

No, this is a solid TIG rod used with the Gas Tungsten Arc Welding (GTAW) process. The shielding is provided by an external gas supply (Argon), not flux.

It is not recommended. While it might physically weld, 316 stainless contains Molybdenum for added corrosion resistance. You should use ER316L filler metal to match the properties of the 316 base metal.
