Description

LH Dealer & Supplier of Alloy-Based Hardfacing Electrodes in Haryana and Chandigarh

LH is a trusted dealer and supplier of high-quality alloy-based hardfacing electrodes in Haryana and Chandigarh. These electrodes deliver exceptional performance in various industrial applications, particularly in industries requiring high abrasion resistance and protection against metal-to-metal wear. Since the alloy basis includes a combination of Fe, C, Cr, and Cb, it ensures these electrodes are ideal for hardfacing components exposed to extreme wear conditions.

Properties of LH Hardfacing Electrodes

The hardfacing electrodes supplied by LH offer numerous advantages, ensuring long-lasting durability and effective performance under harsh conditions:

• Hard Surfacing Electrode: The alloy composition provides a high metal recovery rate of 180%, enhancing deposition efficiency.
• Exceptional Abrasion Resistance: These electrodes retain their hardness and wear resistance, even at temperatures as high as 650°C.
• Easy Arc Control: They ensure easy arc control, particularly in the horizontal position, making them more manageable during welding.
• No Slag Interference: Designed to minimize slag buildup, these electrodes allow for smoother operation and easier post-welding cleanup.

Technical Data

• Hardness: 57-61 Rc (Rockwell C hardness scale), ensuring superior wear resistance.
• Metal Recovery: 180%, which increases the efficiency and cost-effectiveness of the welding process.

Typical Applications

LH hardfacing electrodes are extensively used in industries where components face severe abrasion and metal-to-metal wear, particularly under mild impact and elevated temperatures (up to 510°C). These applications include:

• Refractory press screws
• Brick press screws
• Cement press screws
• Palm nut press screws
• Parts of crushers for friable materials
• Conveyor screws
• Impellers
• Dredging buckets
• Edge runner bottoms
• Pug mills
• Knives, wing knives, and augers
• Boring bits
• Blast furnace bells and hoppers

These electrodes are especially suited for industries like cement production, mining, and manufacturing, where equipment endures both abrasion and impact in challenging environments.

Welding Procedure

When using LH hardfacing electrodes, adhering to the correct procedure is essential for achieving optimal results:

• Use a Medium Arc: Maintain a steady, medium arc to ensure optimal fusion and penetration.
• Use Low Current to Prevent Excessive Dilution: To avoid parent metal dilution, it is advisable to use low current settings.
• Apply Multi-Layer Welding: The desired hardness is achieved after applying the second or third layer of welding.

Welding Current Settings

For best results, use the following welding current settings based on the size of the electrode:

• Size 2.5mm x 350mm: Current range 70-90 amps
• Size 3.2mm x 350mm: Current range 120-140 amps
• Size 4.0mm x 350mm: Current range 140-180 amps
• Size 5.0mm x 350mm: Current range 160-210 amps

LH offers electrodes in various sizes to accommodate different welding needs, providing flexibility for customers across Haryana and Chandigarh.
