FAQs About TIG Filler Rod for Mild Steel

What TIG rod is used for mild steel?

Use ER70S-class filler rods for mild steel, most commonly ER70S-6 or ER70S-2. ER70S-6 wets smoothly and handles light mill scale because it has more deoxidizers. ER70S-2 is great for very clean steel and critical work. Both give strong, ductile welds with argon shielding on DC.

Can TIG be used on mild steel?

Yes, TIG works very well on mild steel and gives clean, precise beads. Run DC electrode negative with pure argon shielding. Use ER70S-6 or ER70S-2 filler and prep joints by removing rust, paint, and oil. TIG shines on thin sheet, small parts, and welds you plan to show.

What is the best TIG electrode for mild steel?

For the tungsten, choose 2 percent lanthanated or 2 percent ceriated for stable starts on DC. A 1/16 inch or 3/32 inch diameter covers most jobs on mild steel. Grind a sharp point along the length for a focused arc. Keep the tip clean and reshape if it contaminated.

Which welding rod is best for mild steel?

If you mean stick welding, E6013 or E6011 are good for general repairs and easy starts. For stronger, cleaner welds in controlled conditions, E7018 is a top choice. Match rod diameter to material thickness and follow the amperage range on the package. Store low hydrogen rods dry to prevent porosity.
