As a result, we deliver factory-direct pricing, consistent carbide quality, and fast delivery. Similarly, this applies to all your mining, cement, quarry, and heavy material handling equipment projects.

In addition, we produce these abrasion resistant weld studs with tungsten carbide inserts that provide superior wear protection. Meanwhile, we comply with ISO 13918 for stud welding and ISO 14555 for arc stud welding procedures. Therefore, maintenance engineers and plant operators rely on them for extending the service life of equipment exposed to severe abrasive wear.

Technical Specifications of Tungsten Carbide Wear Studs

To begin with, we manufacture our wear protection studs in a range of sizes and hardness grades. Specifically, the table below summarizes the standard product range.

Material & Welding Specifications for Abrasion Resistant Wear Studs

• To begin with, we use tungsten carbide (WC-Co) with cobalt content of 6–12% as the standard insert material. This provides high hardness and toughness for our wear studs.
• Moreover, we achieve a hardness range of HRA 86–92 depending on the application. Mining and construction studs typically use HRA 86–89, while extreme wear applications use HRA 89–92.
• Additionally, we manufacture the stud body from chromium carbide-laden alloy or low carbon steel. This provides a ductile base that absorbs impact while the carbide insert resists abrasion.
• Furthermore, we perform drawn arc stud welding per ISO 14555 with ceramic ferrules. This produces a metallurgically bonded weld that is stronger than the base metal alone.
• For special orders, we supply corrosion-resistant grades (WC-Ni) with nickel content of 5–10% for acidic or seawater environments.
• Finally, we offer OEM & ODM — we customize stud diameter, height, carbide grade, insert geometry, and packaging according to your specifications.

How Tungsten Carbide Wear Studs Work — The Dead Bed Effect

In fact, the abrasion resistant weld stud creates a protective layer on equipment surfaces through a unique mechanism called the dead bed effect. Furthermore, this effect dramatically extends the wear life of chutes, hoppers, and crushers.

To begin with, you weld the studs onto the wear surface in an offset hexagonal pattern. Meanwhile, the studs create a rough, protruding surface. Then, as material flows over the studs, fine mineral debris becomes trapped between them. Consequently, the trapped debris forms a protective layer — the dead bed — that covers over 70% of the area.

Therefore, instead of abrasive material wearing against the steel plate, it wears against the trapped debris layer. Moreover, the tungsten carbide inserts themselves resist abrasion. As a result, the combination of the dead bed effect and carbide hardness increases service life by up to three times compared to non-studded surfaces.

Key Advantages of the Dead Bed Effect

• First, the dead bed effect protects the base metal plate from direct abrasive wear.
• Second, the tungsten carbide inserts resist the cutting and gouging action of hard rock and minerals.
• Third, the studs absorb impact energy through the ductile stud body, preventing carbide fracture.
• Finally, only the studs need replacement when worn, not the entire plate. This reduces maintenance cost.

How to Install Tungsten Carbide Wear Studs

1. First, prepare the surface. Clean the wear plate surface to remove rust, scale, oil, and moisture for proper electrical contact.
2. Then, load the stud and ferrule. Place the stud in the stud welding gun and fit the ceramic ferrule around the stud base.
3. Next, position the gun. Press the gun perpendicular to the wear surface at the desired location.
4. After that, activate the weld. The gun lifts the stud, strikes an arc, and plunges the stud into the molten pool. Each weld takes less than 1.2 seconds.
5. Finally, arrange the pattern. Apply the studs in an offset hexagonal pattern so that free flow between studs is blocked by the next row. The tighter the pattern, the better the wear resistance.

About Our Factory — Direct Manufacturer of Tungsten Carbide Wear Studs

In fact, Tarco Industry operates a modern manufacturing facility. Specifically, we dedicate it to the production of tungsten carbide wear studs and abrasion resistant weld studs.

Furthermore, we complete every step in our own factory. This includes carbide powder preparation, hot isostatic pressing, sintering, precision grinding, and stud body assembly. Consequently, we do not outsource production. We do not act as a middleman.

In addition, we equip our factory with advanced HIP sintering furnaces and automated stud welding lines. As a result, we produce high-density tungsten carbide inserts with consistent hardness and reliable weld quality.

Therefore, whether you need standard wear studs or custom carbide grades, Tarco Industry can produce them directly for you.

Factory Direct Advantages

• First, we are a Manufacturer, Not a Trader. You buy directly from Tarco Industry production lines, eliminating middleman markups.
• Second, we handle In-House Production. We produce carbide inserts, stud bodies, and finished studs all under one roof for full quality control.
• Third, we welcome OEM & ODM. We customize stud dimensions, carbide grades, insert shapes, and packaging.
• Fourth, we maintain Bulk Production Capacity. We ensure stable output for large mining and cement plant orders.
• Finally, we provide Factory Price. We offer competitive direct pricing for distributors, maintenance contractors, and plant operators.

Why Choose Our Tungsten Carbide Wear Studs?

• For example, our studs offer Superior Abrasion Resistance. Tungsten carbide inserts at HRA 86–92 resist the most severe sliding abrasion conditions.
• In addition, they provide Dead Bed Effect Protection. The offset stud pattern traps mineral debris to create a protective layer over 70% of the area.
• Moreover, they feature Impact Resistance. The ductile stud body absorbs impact energy while the carbide insert resists wear.
• Furthermore, they ensure Full Fusion Welding. The drawn arc process per ISO 14555 produces a metallurgically bonded weld that resists vibration.
• As a result of their Replaceable Design, only the studs need replacement when worn, not the entire wear plate.
• Finally, we provide Direct Factory Support. Tarco Industry provides technical guidance, samples, and custom production.

Applications & Industries for Tungsten Carbide Wear Studs

• For instance, in mining and quarrying, plant operators use our studs on crusher parts, chutes, hoppers, and mobile plant equipment.
• Also, in cement plants, they protect clinker drop zones, bulk material liners, and cyclone plates from severe abrasion.
• In addition, for loader buckets and excavator buckets, they extend the service life of high-wear surfaces.
• Furthermore, in recycling and scrap metal, they protect shredder housings and protection plates.
• Lastly, in asphalt plants and rock saws, they provide wear protection for critical equipment surfaces.
