Smooth Wear Plate for Abrasion Protection Without Visible Weld Channels or Material Blocking
HALDEN smooth wear plate is a premium smooth-surface chromium carbide overlay plate developed through a submerged arc welding production process. Compared with traditional open-arc CCO plate, the surface has no visible weld channels, offers a flatter appearance, reduces material blocking risk, and maintains strong abrasion resistance for bulk material handling, chutes, hoppers, liners, and high-wear industrial equipment.
Traditional Weld Bead Surfaces Can Create Material Blocking, Flow Resistance, and Uneven Sliding Wear.
Smooth wear plate provides a flatter overlay surface while keeping the abrasion resistance expected from chromium carbide overlay materials.
Key Information Needed Before Selecting Smooth Wear Plate
To recommend the correct smooth wear plate structure, HALDEN needs to know the application, material handled, particle size, sliding speed, impact level, operating temperature, liner size, required thickness, installation method, and whether the plate needs cutting, bending, drilling, countersinking, plug-weld holes, or tailor-made fabrication.
Material Flow Requirement
Smooth surface is useful when material must slide without being blocked by visible weld channels or rough overlay beads.
Abrasion Severity
Smooth wear plate is suitable for abrasive sliding wear in chutes, hoppers, feeders, transfer points, and bulk handling liners.
Thickness Selection
Standard combinations include 6+4, 6+6, 8+6, 8+8, 10+8, 10+10, 12+8, 12+10, and other customized structures.
Installation Method
Smooth wear plates can be processed into liner plates according to drawings for easier installation and replacement.
What Is Smooth Wear Plate?
Smooth wear plate is a chromium carbide overlay wear plate with a flatter and smoother surface compared with conventional open-arc overlay plate. HALDEN developed a submerged arc welding process for smooth wear plate production, so the overlay surface has no visible weld channels while retaining strong abrasion resistance.
No Visible Weld Channels
The overlay surface is smooth and flat, helping reduce material blocking and improving material flow behavior.
Strong Abrasion Resistance
HALDEN states that the forming process is different, but the wear resistance is not different from open arc welding overlay plate.
Custom Liner Processing
Smooth wear plate can be processed into liner plates according to drawings, making installation easier for customer-specific equipment.

Smooth Wear Plate vs Traditional Open Arc CCO Plate
Smooth wear plate is not simply a cosmetic version of CCO plate. It is designed for applications where both abrasion resistance and smoother material flow are important.
| Comparison Item | Smooth Wear Plate | Traditional Open Arc CCO Plate |
|---|---|---|
| Surface Appearance | Smooth and flat surface with no visible weld channels. | Visible weld bead channels are usually present. |
| Material Flow | Better for reducing material blocking and improving smooth sliding. | Weld channels may catch fine, sticky, or bridging material in some conditions. |
| Wear Resistance | HALDEN states wear resistance is not different from open arc welding overlay plate. | Strong abrasion resistance in standard CCO wear liner applications. |
| Typical Use | Chutes, hoppers, liners, feeders, transfer areas, and applications where material blocking must be reduced. | General severe abrasion liners where visible bead channels are acceptable. |
| Processing | Can be processed into custom liner plates according to drawings. | Can also be cut, formed, rolled, drilled, or fabricated depending on design. |
Typical Smooth Wear Plate Applications
Smooth wear plate is especially useful when a wear liner must resist abrasion while allowing bulk material to flow smoothly over the surface.
Smooth Wear Plate Selection Guide
Smooth wear plate should be selected by material flow behavior, wear mechanism, impact level, temperature, fixing method, and expected service life.
| Working Condition | Recommended Direction | Buyer Note |
|---|---|---|
| Fine or sticky material blocking | Smooth surface wear plate | No visible weld channels can help reduce material blocking risk. |
| Severe sliding abrasion | Smooth chromium carbide overlay plate | Provides abrasion resistance while improving surface flow behavior. |
| High direct impact | Review hybrid liner or tougher backing design | Very high impact zones may require more than a hard overlay surface. |
| Custom liner shape | Cut-to-drawing smooth wear liner | Send drawings, hole positions, fixing method, and bending requirement. |
| Need chemical adjustment | Customized wear-resistant layer composition | HALDEN can adjust element content according to different working conditions. |
| General CCO liner replacement | Compare smooth plate and standard open-arc CCO plate | Choose smooth type when surface flow and flatness provide real site value. |
Custom Processing and Fabrication Options
HALDEN can process smooth wear plate into liner plates according to customer drawings, making installation easier for equipment repair and replacement projects.
Cut-to-Size Liners
Plates can be cut into rectangular, angled, segmented, curved, or irregular liner shapes according to drawings.
Hole Preparation
Bolt holes, countersunk holes, plug-weld holes, installation slots, and custom fixing patterns can be prepared.
Bending and Forming
Smooth wear plate can be processed into liners for chutes, hoppers, cones, transitions, and feeder surfaces after design review.

Important Note: Smooth Surface Does Not Mean Lower Wear Resistance
According to the original HALDEN page, the technology is different in forming process, but the wear resistance is no different from open arc welding. Smooth wear plate is selected when the site needs both abrasion resistance and improved material flow behavior.
