ER937-116 - A2 Tool Steel TIG Welding Rod 1/16" - 10lb Tube

Reliable Tool & Die Repair with A2 TIG Rods

For welders tasked with the critical job of tool and die maintenance, the A2 Tool Steel TIG Rod (1/16" x 36") is an essential addition to your filler metal arsenal. Tool steel repair is an art that requires not just skill, but the right materials. This A2 alloy rod is designed to match the chemistry and performance of standard air-hardening tool steels, ensuring that your repairs hold up under the extreme pressures and abrasion of industrial stamping and forming operations. Packaged in a durable 10 lb tube, these rods are kept straight and protected from moisture and shop dirt until you are ready to strike an arc.

Why choose A2? It sits in the "sweet spot" of tool steels. It offers better wear resistance than O1 (oil-hardening) steels and is tougher than D2 (high-carbon/high-chrome) steels. This makes it incredibly versatile for a wide range of applications, from fixing chipped shear blades to rebuilding worn punch faces. The 1/16-inch diameter is particularly useful for fine detail work, allowing you to build up edges with precision without dumping excessive heat into the part, which could distort the expensive tool you are fixing. The rod deposits a dense, crack-resistant bead that can be machined or ground to final dimensions after welding.

Successful application of this rod typically involves preheating the workpiece to prevent thermal shock and cracking. Once welded, the deposit air-hardens, restoring the tool's ability to hold a sharp edge. It is an excellent solution for "saving" expensive tooling that would otherwise be scrapped due to wear or engineering changes. Whether you are working in a dedicated tool and die shop or a general maintenance department, having A2 TIG rods on hand ensures you can respond quickly to tooling failures and keep production lines moving. Use with pure Argon gas and standard DCEN (Direct Current Electrode Negative) TIG setups for best results.
