IANICRM03-125E - Exocor Inconel 625 Stick Electrode 1/8" 10lb Tube

Exocor Inconel 625 Stick Rod – The Problem Solver

When you are up against a job that requires extreme heat resistance or needs to survive in a corrosive nightmare, the Exocor ENiCrMo-3 (Inconel 625) stick electrode is the rod you reach for. This isn't your average mild steel rod; this is a high-grade nickel-alloy electrode designed to weld the "unweldable" and withstand environments that would eat standard steel for breakfast. Whether you are repairing a heat exchanger, welding dissimilar metals, or overlaying a shaft, this 1/8" rod delivers professional results with the reliability you expect from Exocor.

Welders know that nickel alloys can be sluggish and difficult to control, but Exocor has formulated this coating to improve runability significantly. You get a smooth, soft arc with low spatter levels, which is crucial when working on expensive base materials where cleanup needs to be minimal. The slag lifts easily—often curling up on its own as it cools—revealing a bright, shiny bead with excellent wash-in at the toes. It runs on DC+ polarity, giving you the penetration needed for root passes while remaining manageable for out-of-position work like vertical-up or overhead welds.

Why Choose This Rod?

The versatility of the ENiCrMo-3 is unmatched. It is often called the "universal repair rod" because it can successfully join carbon steel to stainless steel, stainless to nickel alloys, and even difficult-to-weld steels. If you aren't sure exactly what alloy you are welding to, or if you are dealing with a transition joint where thermal expansion is a concern, this rod is your safest bet. It resists cracking during solidification, a common headache with other alloy rods.

Practical Welding Tips

• Cleanliness is Key: Nickel alloys are sensitive to contaminants. Ensure the base metal is completely free of oil, grease, paint, and sulfur before striking an arc.
• Heat Control: Maintain a short arc length to protect the puddle from atmospheric contamination. Avoid excessive weaving; stringer beads are recommended to keep heat input low.
• Storage: These rods come in a 10lb tube. If opened, keep them in a rod oven (typically around 250°F-300°F) to prevent moisture pickup, which can cause porosity.
• Restarts: When restarting a weld, strike slightly ahead of the crater and move back to remelt the crater before continuing forward to avoid cold lap.
