Best Tungsten for Stainless Steel Tig Welding: FAQ

Q1: What is the best type of tungsten for stainless steel TIG welding?

A1: For general-purpose stainless steel TIG welding, 2% Lanthanated (blue tip) tungsten electrodes are highly recommended due to their excellent arc starting, stability, and versatility with both AC and DC currents. 2% Ceriated (gray tip) tungsten is also a great choice, especially for lower amperage applications and arc stability. Thoriated (red tip) tungsten offers superior DC arc stability but requires special handling due to its radioactive properties.

Q2: Can I use the same tungsten for AC and DC TIG welding stainless steel?

A2: Yes, lanthanated (blue tip) and ceriated (gray tip) tungsten electrodes are excellent for both AC (alternating current) and DC (direct current) TIG welding. This makes them a versatile option if you work with various materials, including stainless steel on DC and aluminum on AC. Thoriated (red tip) tungsten is primarily optimized for DC welding.

Q3: What size tungsten electrode should I use for stainless steel?

A3: The appropriate tungsten electrode diameter depends on the thickness of the stainless steel you’re welding and the amperage you’ll be using. Common sizes for stainless steel TIG welding include 1/16″ (1.6 mm), 3/32″ (2.4 mm), and 1/8″ (3.2 mm). Thicker material and higher amperage usually require a larger diameter tungsten to prevent overheating.

Q4: Why are ER308L welding rods mentioned in an article about tungsten?

A4: While tungsten electrodes carry the arc, ER308L welding rods are the essential filler metal used to create the actual weld bead when TIG welding stainless steel. They are crucial for building up the joint and ensuring the weld has the correct metallurgical properties, like corrosion resistance, matching the base stainless steel. The article includes them because selecting the right filler rod is as important as selecting the right tungsten for a successful stainless steel TIG weld.

Q5: Is red tip (thoriated) tungsten still safe to use for stainless steel?

A5: Red tip (thoriated) tungsten is highly effective for DC TIG welding stainless steel due to its exceptional arc stability and long life. However, it contains radioactive thorium, which poses potential health risks from inhaling grinding dust or fumes. If you choose to use it, ensure you have excellent ventilation and proper personal protective equipment (PPE), and consider grinding in a dedicated, well-ventilated area with proper dust collection. Many welders are switching to non-radioactive alternatives like lanthanated or ceriated for safety reasons.

Q6: What shielding gas should I use for TIG welding stainless steel with these tungsten options?

A6: For TIG welding stainless steel, 100% Argon is the most common and recommended shielding gas. It provides excellent arc stability, good penetration, and a clean weld puddle. For increased penetration and higher welding speeds, especially on thicker stainless steel, a mixture of Argon/Helium can also be used, though it’s typically more expensive.

Q7: How does a TIG wire feeder pen help with stainless steel welding?

A7: A TIG wire feeder pen, like the one included with the WelderElite package, helps maintain consistent and smooth filler wire feeding into the weld puddle. This is particularly beneficial for stainless steel, where precision and consistent travel speed are important for achieving uniform, clean beads. It reduces hand fatigue and can help welders of all skill levels produce more professional-looking welds.
