132 Wear-Resistant Welding Rod is primarily used for the overlay welding or repair of worn low-carbon steel, medium-carbon steel, and low-alloy steel, especially suitable for worn parts of mining machinery and agricultural machinery.
D132 Wear-Resistant Welding Rod features stable arc and easy slag removal, making it suitable for both AC and DC applications.
Specific Application Scenarios
1. Mining Machinery: Used for overlay welding and repair of worn parts in mining machinery, such as digging buckets and components of mining equipment.
2. Agricultural Machinery: Used for overlay welding and repair of worn parts in agricultural machinery, such as deep plowshares and tractor scrapers.
Physical Properties
Hardness: Overlay welding layer hardness HRC ≥ 30
Welding Current: Different diameters of welding rods have different welding current ranges. For example, Φ3.2 rods have a welding current of 80~130A, Φ4.0 rods have a welding current of 110~180A, and Φ5.0 rods have a welding current of 150~240A.

Usage Precautions
Pre-Welding Treatment: The welding rod needs to be baked at around 150°C for 1 hour before use.
Preheating: Large workpieces should be appropriately preheated to around 300°C before overlay welding, and rust and oil stains on the surface of the welding area should be removed.
