OVERVIEW

Premium Grade ER4130 TIG Welding Rods

The Exocor ER4130 TIG Welding Rod is a high-performance low-alloy steel filler metal designed specifically for the Gas Tungsten Arc Welding (GTAW) of high-strength steels. Formulated with a precise balance of Chromium and Molybdenum, this rod is engineered to match the chemical and mechanical properties of AISI 4130 and 4140 base materials. This chemical compatibility is critical for applications where the weldment must undergo post-weld heat treatment (PWHT) to achieve uniform hardness and strength across the joint and heat-affected zone (HAZ).

Industrial fabricators and MRO professionals rely on Exocor 4130 for its consistency and metallurgical integrity. The rod is manufactured to strict tolerances, ensuring a clean surface finish free from drawing lubricants and oxides that could introduce hydrogen or other contaminants into the weld pool. With a diameter of 0.062" (1/16"), this filler metal provides excellent versatility for welding thin-wall tubing and sheet metal often found in specialized structural applications. The 36-inch cut lengths are standard for manual TIG feeding, providing the welder with optimal reach and control.

In terms of mechanical performance, the Exocor ER4130 deposit offers high tensile strength and ductility when properly heat treated. It is the preferred choice for critical structural components where failure is not an option. The alloy's response to hardening and tempering cycles makes it indispensable in industries requiring lightweight yet extremely strong frameworks. Whether used for repair operations on existing machinery or the fabrication of new high-performance assemblies, this filler metal ensures that the weld joint does not become the weak link in the structure.

Technical Specifications

This filler metal meets relevant industry standards for low-alloy steel electrodes. It is designed for use with 100% Argon shielding gas to maintain arc stability and protect the molten pool from atmospheric contamination. The 1/16" diameter is particularly well-suited for root passes in pipe welding or for single-pass welds on thinner gauge materials. Proper storage in a dry environment is recommended to maintain the rod's premium condition and prevent moisture pickup.

FAQ

This rod typically conforms to AWS A5.28 class ER4130, designed for welding high-strength low-alloy steels.

While physically possible, it is not recommended. ER4130 is more expensive and the weld deposit will be hard and potentially brittle if not heat treated. Use ER70S-6 for mild steel.

ER4130 is designed to be heat treated. If the weldment will not be heat treated, some fabricators prefer ER70S-2 or ER80S-D2 for better ductility in the as-welded condition, depending on the application engineering requirements.

100% Argon is the standard shielding gas for TIG welding with ER4130 rods.

Yes, preheating (typically 300°F - 400°F) is often required when welding 4130 to prevent cracking, especially on thicker sections or complex joints.

This specific item is 0.062 inches, which is 1/16 of an inch (approx 1.6mm).

ER4130 matches the chemical composition of the base metal, allowing the weld to respond to heat treatment (hardening/normalizing) in the same way as the parent material.

Yes, ER4130 is commonly used in aviation for welding 4130 airframes, provided all relevant aviation welding standards and procedures are followed.
