Properties

The LH electrode is a basic electrode with excellent welding characteristics, making it an economical choice for hard overlays in all positions. It produces regular beads and provides deposits that are hard, tough, and free from porosity, ensuring high-quality welds in a variety of applications.

Technical Data

• Hardness: 56-58 RC

Typical Applications

The LH electrode is ideal for surfacing parts exposed to heavy abrasive wear and mild impact. It is commonly used in industries for:

• Digger Teeth
• Drills
• Conveyor Screws
• Cutting and Forming Tools
• Punches
• Hotwork Dies
• Shear Blades
• Crusher Hammers and Jaws
• Crane Wheels
• Conveyor Buckets
• Plough Shears
• Cultivators
• Pulverizers
• Skids
• Mixers
• Oil Expeller Worms

Additionally, it is effective for manganese steel parts that experience high abrasion.

Procedure

For best results, thoroughly clean the surface before welding. Remove any cracked or spalled metal to ensure a clean welding surface. The LH electrode is suitable for both single and multi-pass hardfacing. For multi-pass welding, apply a buffer layer using LH 108. To achieve the recommended hardness, weld at least three layers. After welding, slow cooling is advised. This can be done using an oven or asbestos to prevent any cracking or warping.

Welding Current

The LH electrode is compatible with both AC and DC (+) power sources, ensuring versatile application across various welding machines. It comes in the following sizes and current ranges:

• Size (∅ mm) / Length: 3.2×350, 4.0×350, 5.0×350
• Current Range (amps):
  • 3.2×350: 100-130 amps
  • 4.0×350: 110-180 amps
  • 5.0×350: 160-220 amps
