High-Performance Ferritic-Austenitic Welding Electrodes

Introduction: If you’re searching for a reliable welding electrode supplier near you in Himachal Pradesh, look no further. LH welding electrodes are specifically designed for high-strength applications that demand crack resistance, superior corrosion resistance, and excellent performance under friction and impact. Our ferritic-austenitic welding electrodes, formulated with a unique combination of materials, ensure smooth, defect-free welds with exceptional durability in harsh environments.

Alloy Basis:

• Iron (Fe)
• Chromium (Cr)
• Nickel (Ni)
• Manganese (Mn)

Properties: Our ferritic-austenitic welding electrodes are engineered for ease of use, producing a soft arc and smooth, defect-free welds with approximately 30% ferrite content. These electrodes provide the following benefits:

• High Strength and Crack Resistance: Ensuring welds are strong and resistant to cracking under stress.
• Superior Resistance: Effective against friction, corrosion, work-hardening, and shock.

Technical Data:

• Ultimate Tensile Strength (UTS): 70-85 kgf/mm²
• Elongation: 22-24%

This combination of strength and ductility makes LH electrodes perfect for heavy-duty applications, ensuring that your welds maintain their integrity under challenging conditions.

Typical Applications: Our high-performance ferritic-austenitic electrodes are suitable for a wide range of applications, including:

1. Heavy Machinery and Equipment Parts: Ideal for parts exposed to heavy wear, like earth-moving equipment, automobile springs, and trunnions of cement mills.
2. High Temperature and Impact Applications: Excellent for parts subjected to heat, corrosion, and impact.
3. Joining High and Low Alloy Steels: Perfect for high carbon steels, low and high alloy steels, tool steels, spring steels, manganese steels, and more.
4. Dissimilar Steel Welding: Ideal for joining dissimilar steels, ensuring a reliable and durable bond.
5. Surfacing Applications: Used for surfacing grooved rolls and repairing drop-forge dies.

Procedure for Optimal Results:

To achieve the best welding results with LH electrodes:

1. Clean the weld area thoroughly before starting.
2. Prepare joint edges properly to ensure a smooth weld.
3. For high carbon and high alloy steels, preheat to 200-250°C to prevent cracking, followed by slow cooling after welding.
4. Use a short arc and a stringer bead technique for enhanced control.
5. Hot peening is recommended for additional strength.
