FAQs About TIG Welding Rods

What TIG welding rods do I use for mild steel?

For mild and low-alloy steel, most welders use ER70S-2 or ER70S-6 filler rods. These rods provide good strength, ductility, and smooth weld puddle control when running DC with argon shielding gas. ER70S-6 is especially popular because it handles mill scale and rust better. They are reliable for both shop and field work.

What TIG welding rods are best for stainless steel?

The best rod depends on the grade of stainless you are welding. For common 300-series stainless like 304 or 316, use matching fillers such as ER308L, ER309L, or ER316L. Choosing the right rod keeps corrosion resistance, color match, and mechanical properties consistent. Always confirm the filler matches the base metal series.

Which TIG welding rods should I use for aluminum?

For aluminum, the rod must match the type of alloy you are welding. ER4043 is commonly used on cast parts and gives smooth flow, while ER5356 works well on wrought plate and extrusions for stronger joints. Always run AC with argon shielding to get proper cleaning action on the weld. Match the rod to the job for best results.

What rod diameter should I pick?

Choose rod size based on the thickness of the base metal. Small diameters like 1/16" are better for thin sheet because they control heat and prevent burn-through. Larger diameters like 3/32" or 1/8" are better for thicker joints to deposit filler faster. Start small, then size up as the material gets thicker.

Can I use one TIG welding rod for everything?

It’s not recommended to use just one filler for all jobs. Each base metal needs a specific rod to get strong welds, prevent cracking, and maintain properties like corrosion resistance. Using the wrong rod can cause weak joints and poor appearance. Matching the filler to the metal gives the best results.

Do TIG welding rods have an expiration date or go bad?

TIG rods don’t have an expiration date, but they can get contaminated if stored poorly. Moisture, oil, and dust on the rods can cause porosity or weak welds. Keep them sealed in a dry container or tube to protect them. Wipe rods clean before use to ensure a strong, clean weld.
