Bacchette di saldatura temprate
Hardened welding rods and tubes are essential components for hardfacing and overlay applications, fornendo superfici resistenti all'usura to steel parts and pipelines.
By using high-hardness welding consumables, industries such as minerario, cemento, energia, and material handling can achieve long-lasting protection, reduced downtime, and improved operational efficiency.
- Descrizione
Bacchette di saldatura temprate are specially designed consumables for hardfacing or overlay welding, fornendo estrema resistenza all'abrasione e agli urti to industrial equipment.
They are commonly used to deposit a wear-resistant layer on steel surfaces, tubi, and tubes, extending the service life of machinery in minerario, cemento, energia, e industrie di movimentazione dei materiali.
Types of Hardened Welding Consumables
1. Hardfacing Welding Rods
-
Materiale: Typically carburo di cromo, high carbon steel, or cobalt alloys.
-
Form: Stick, wire, or flux-cored rods.
-
Overlay Hardness: 50–65 HRC depending on alloy.
-
Applicazioni:
-
Fodere del frantoio, tramogge, bucket edges
-
Lame del miscelatore, screw conveyors, cade
-
Shredder blades and impact surfaces
-
Vantaggi:
-
Easy to use in manual or semi-automatic welding
-
Deposits uniform hardfacing layers with excellent wear resistance
-
Adatto per repairing or reinforcing worn parts
2. Hardfacing Tubes / Pipes
-
Definizione: Tubes or pipes that have a hardfacing overlay welded or lined internally.
-
Scopo: Protects pipelines carrying abrasive slurry, minerale, carbone, or sand from erosion and wear.
-
Overlay Material: Chromium carbide or tungsten carbide layers applied inside or outside the tube.
-
Applicazioni:
-
Slurry pipelines in mining
-
Coal or cement chutes and feeders
-
Hydraulic and pneumatic wear-resistant lines
-
Vantaggi:
-
Riduce erosion and abrasion in pipelines
-
Extends the life of critical material handling systems
-
Can be customized with specific overlay thickness and tube dimensions
