硬化した溶接棒

硬化した溶接棒 are specially designed consumables for hardfacing or overlay welding, 提供 extreme abrasion and impact resistance to industrial equipment.
They are commonly used to deposit a wear-resistant layer の上 steel surfaces, パイプ, and tubes, extending the service life of machinery in 採掘, セメント, 力, and material handling industries.

Types of Hardened Welding Consumables

1. Hardfacing Welding Rods

• 材料: 通常 炭化クロム, high carbon steel, or cobalt alloys.

• Form: Stick, wire, or flux-cored rods.

• オーバーレイ硬度: 50–65 HRC depending on alloy.

• アプリケーション:

  • クラッシャーライナー, ホッパー, bucket edges

  • ミキサーブレード, スクリューコンベア, 滝

  • Shredder blades and impact surfaces

利点:

• Easy to use in manual or semi-automatic welding

• Deposits uniform hardfacing layers with excellent wear resistance

• に適しています repairing or reinforcing worn parts

2. Hardfacing Tubes / パイプ

• 意味: Tubes or pipes that have a hardfacing overlay welded or lined internally.

• 目的: Protects pipelines carrying abrasive slurry, 鉱石, 石炭, or sand from erosion and wear.

• オーバーレイマテリアル: Chromium carbide or tungsten carbide layers applied inside or outside the tube.

• アプリケーション:

  • Slurry pipelines in mining

  • Coal or cement chutes and feeders

  • Hydraulic and pneumatic wear-resistant lines

利点:

• Reduces erosion and abrasion in pipelines

• Extends the life of critical material handling systems

• Can be customized with specific overlay thickness and tube dimensions
