14924 - UTP 73 G 2 H13 Tool Steel Repair Electrode 1/8"

Restore and Protect Hot Work Tools

When expensive dies and molds begin to show signs of heat checking or wear, the UTP 73 G 2 H-13 Stick Electrode is your go-to solution for reliable restoration. Designed specifically for welders working on hot work tool steels, this 1/8" (3.2mm) rod deposits high-quality steel that matches the popular H13 grade. Whether you are repairing aluminum die-casting molds, forging dies, or hot shear blades, this electrode provides the toughness and heat resistance needed to withstand punishing industrial cycles.

One of the biggest challenges in tool repair is preventing cracking during the welding process. The UTP 73 G 2 is formulated to offer excellent crack resistance, provided proper preheat and interpass temperatures (typically around 400°C) are maintained. The rutile-basic coating ensures a smooth arc and minimal spatter, giving you better control over the puddle—essential when building up edges or filling cavities on precision parts. The slag lifts easily, reducing cleanup time and the risk of slag inclusions in multi-pass welds.

The resulting weld deposit is tough and hard (approx. 55 HRC), capable of resisting the thermal shock that causes "fire cracking" in tools. If the part requires machining after welding, the deposit can be worked with tungsten carbide tools. This 4.8kg box provides ample material for significant refurbishment projects, helping your shop save money by salvaging worn tools rather than replacing them.

Application Tips:

• Preparation: Remove all fatigued or cracked material before welding.
• Preheat: Preheat the workpiece to 400°C and maintain this temperature during welding to prevent stress cracking.
• Cooling: Allow the part to cool slowly in a furnace or insulating material to minimize residual stresses.
• Post-Weld: Tempering is recommended to align the hardness with the base tool requirements.
