Alloy Electrode for Cast Iron Welding: A Superior Solution for Cold Welding and Repair

When welding cast iron, selecting the right electrode is essential for achieving a smooth, stable arc, reducing heat-affected zones, and ensuring durability. The Alloy Electrode is an excellent choice for both cold welding cast iron and joining it to mild steel. Its unique properties make it ideal for a variety of applications, including intricate repairs and surfacing cast iron parts. LH Distributor & Supplier in Chandigarh & Haryana

Properties of the Alloy Electrode

• Smooth, Stable Arc: Known for its smooth, stable arc, this electrode makes welding more predictable and controlled.
• Positional Welding: Ideal for welding in positions that are difficult to reach, ensuring flexibility in various applications.
• Minimal Base Material Mixing: The electrode reduces mixing with the base material, helping to prevent distortion and keep the heat-affected zone machinable.
• No Undercut: It avoids undercut, a common welding issue that can compromise joint integrity.

Technical Data

• Ultimate Tensile Strength (UTS): 32-38 kgf/mm², making it robust enough for demanding, heavy-duty applications.

Typical Applications

The Alloy Electrode is highly versatile and can be used in the following:

• Cold Welding of Cast Iron: No preheating is required, saving time and energy during repairs.
• Joining Cast Iron to Mild Steel: It bonds cast iron to mild steel, creating strong, lasting joints.
• Surfacing Cast Iron Parts: Ideal for surfacing parts exposed to erosion, corrosion, or high temperatures.
• Intricate Cast Iron Repairs: Perfect for repairing delicate parts like water pump housings, electric motor bodies, machine frames, and gears.
• Salvaging Castings and Machinery: Suitable for salvaging foundry castings, gearboxes, differential housings, lathe beds, sugar mill rollers, glass molds, and cast iron dies.

Using the Alloy Electrode

1. Surface Preparation: Clean the welding area and check for cracks or defects that could affect the quality of the weld.
2. Welding Technique: Use a short arc and low current to deposit a stringer bead, not exceeding 50mm in length. This helps control heat input and improves weld quality.
3. Peening: After welding, peen the deposit to reduce residual stresses, ensuring a durable, strong joint.

Welding Current Specifications

• Current Type: AC / DC (–)
• Electrode Sizes:
  • 2.5mm x 350mm
  • 3.2mm x 350mm
  • 4.0mm x 350mm
• Recommended Current:
  • 2.5mm: 40-75 Amps
  • 3.2mm: 70-110 Amps
  • 4.0mm: 90-140 Amps

These specifications make the electrode suitable for a wide range of welding conditions.
