OVERVIEW

Reliable ER347 TIG Rods for Stabilized Stainless

When you are welding stabilized stainless steels like 347 or 321, you need a filler metal that matches the base material's performance. The Exocor ER347 TIG Rod in 5/32" is your go-to solution for these demanding jobs. This rod is alloyed with Niobium, which acts as a stabilizer to prevent the intergranular corrosion that can occur in standard stainless welds when they are heated. If you are working on exhaust manifolds, heat exchangers, or chemical tanks, this rod ensures your welds hold up over time.

Welders will appreciate the smooth feeding and stable arc characteristics of the Exocor ER347. The 5/32" diameter is perfect for filling larger joints or working on thicker plate material where you need to lay down metal efficiently without sacrificing control. The clean finish on the rods minimizes contamination in the weld pool, helping you achieve that stack-of-dimes look with excellent wetting action. It flows smoothly and ties in well at the toes, reducing the need for excessive post-weld grinding or cleanup.

Packaged in a convenient 10lb tube, these rods stay protected from moisture and dirt until you are ready to use them. Whether you are repairing a high-pressure vessel or fabricating custom stainless components, trust Exocor ER347 to deliver the strength and corrosion resistance your project demands. It is the professional's choice for ensuring that the weld is as durable as the base metal itself.

Why Welders Choose This Rod

  • Smooth Arc: Consistent burn-off and excellent puddle control.
  • Crack Resistance: Formulated to resist cracking in high-restraint joints.
  • Perfect Match: The ideal color and property match for 347 and 321 stainless.

FAQ

ER347 contains Niobium (Columbium) as a stabilizer, which prevents intergranular corrosion (carbide precipitation) at high temperatures. ER308L is for standard 304/304L stainless and does not have this stabilizer.

Yes, ER347 can be used to weld 304 stainless steel, but it is generally overkill unless the application involves high temperatures where stabilization is required. ER308L is the standard choice for 304.

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

It is specifically designed for welding ASTM 347 and 321 stainless steels, but can also be used for 304 and 302 grades.

The 5/32" diameter is approximately equivalent to 4.0mm.

Niobium reacts with carbon to form stable carbides, preventing the carbon from reacting with chromium. This preserves the chromium content for corrosion resistance, preventing 'weld decay'.

Yes, ER347 is excellent for high-temperature service and offers good creep strength.

Use DCEN (Direct Current Electrode Negative) for TIG welding with this stainless rod.
