Stainless Steel TIG Weld Wires

The right filler rod is as important as the right tube. This collection covers the Vibrant Performance stainless steel TIG welding wires, including ER309L, which is the standard choice for joining stainless to mild steel, in common rod diameters.

Choosing a filler

Use ER308L for T304 to T304, ER309L for stainless to mild steel, and ER316L where extra corrosion resistance is needed.

Which diameter? 1/16 inch suits typical 16 gauge exhaust tubing, and 3/32 inch suits thicker flanges.

How to Choose

Match the tube outside diameter and material to the rest of your build. 304 stainless is the most common choice for exhaust, 321 stainless handles the extreme heat of turbo manifolds and headers, titanium saves weight, and aluminum is the go-to for intake and intercooler piping. Wall thickness and bend radius matter when you need parts to fit together cleanly.

Common Questions

Do I need to back purge stainless when welding?

Yes. Back purging with argon keeps the inside of the weld from sugaring, which gives you a stronger, cleaner joint.

Can I mix stainless and mild steel?

You can weld them together with the right filler, but the joint can rust over time. For best results keep the system one material.
