OVERVIEW

Reliable Welding with Exocor ER347

When you are welding stabilized stainless steels like grade 347 or 321, you need a filler metal that matches the base material's durability and heat resistance. The Exocor Executive ER347 TIG rod is your go-to solution. This 1/16-inch rod is packed with features that make your job easier and your welds stronger. The "Executive" line from Exocor is known for its cleanliness and consistency; you won't be fighting with dirty wire or inconsistent diameters here. Each rod feeds smoothly through your hand, allowing for precise puddle manipulation and a bead appearance that you can be proud of.

The magic inside this rod is the addition of Niobium. While that might sound like just another element on the periodic table, for a welder, it means peace of mind. It prevents the weld from corroding from the inside out when the part heats up in service. This makes it perfect for welding things like exhaust manifolds, heat exchangers, or chemical tanks that get hot and stay hot. If you've ever had a stainless weld fail because of "sugaring" or corrosion right next to the bead, using a stabilized rod like this (on the right base metal) is often the fix.

These rods come in a sturdy 10lb tube, keeping them straight and protecting them from shop dirt and moisture until you're ready to burn them. They run best with 100% Argon gas. Whether you are doing critical pipe work or fabricating custom parts for the food processing industry, Exocor ER347 gives you the control and quality you need to pass X-ray and visual inspections with flying colors.

FAQ

ER347 contains Niobium (Columbium) which stabilizes the steel against intergranular corrosion at high temperatures, whereas ER308L is a standard grade for 304 stainless. ER347 is specifically for welding 347 and 321 base metals.

Yes, you can use ER347 to weld 304 stainless steel, but it is generally not cost-effective as ER308L is the standard filler. However, ER347 is required if the base metal is 347 or 321.

100% Argon is the standard shielding gas for TIG welding with ER347 rods.

DCEN (Direct Current Electrode Negative), also known as Straight Polarity, is used for TIG welding stainless steel.

Niobium acts as a stabilizer that prevents chromium carbide precipitation, thereby protecting the weld area from intergranular corrosion in high-temperature service environments.

Yes, provided the base material is also suitable and the weld is finished correctly. 347 is often used in food processing where high heat is involved.

This specific SKU is for 0.062" (1/16") diameter rods.

Yes, commercial specifications for Niobium stabilization in stainless steel typically include a small amount of Tantalum, which functions similarly to Niobium.
