As a key technology in the field of surface engineering, laserbekleding has undergone decades of evolution and is now widely applied in industries such as mechanical manufacturing, petrochemicals, and aerospace for component repair and reinforcement. For a long time, the industry held a rigid understanding that laserbekleding meant “laser cladding powder,” with wire material being relegated to the domain of arc welding. This understanding remained until Greenstone-tech broke through the technical barriers, integrating wire materials into the laserbekleding system, pushing laserbekleding technology into a new era of dual pathways: “powder and wire.”

Core Differences Between Powder and Wire in Laser Cladding

The primary difference between laser cladding powder en laser cladding wire lies in the form of the cladding material. This difference directly affects the technical route, process parameters, coating performance, and processing costs:

Laserbekleding powder: Using materials such as stainless steel powder, WC powder, and nickel-based alloy powder, this technique benefits from the small size and uniform laser absorption of the powder particles. It allows for precise control of the cladding layer’s composition and thickness, making it the current industry mainstream. However, it has notable drawbacks: when processing non-ferrous metals like titanium, copper, and aluminum powders, pore defects and poor microstructure often occur. Moreover, the production, storage, and transportation of powders are expensive, and 15%-30% of the powder is wasted during the cladding process, significantly increasing the overall cost.

Laserbekleding wire: Using metal wires as raw materials, it offers a wider selection, including stainless steel, nickel, copper, titanium, and other non-ferrous metal wires. The coatings produced are more flexible, crack-resistant, and have lower porosity. Traditionally, wire materials struggled with laser absorption, relying heavily on arc welding. Greenstone-tech’s innovative multi-beam technology has addressed this issue, enabling laser cladding wire technology to overcome its previous limitations and surpass the powder-based technique in non-ferrous metal processing and cost control.

Greenstone-tech: Leading the Diversification of Laser Cladding Technology

As a leader in the domestic laserbekleding industry, Greenstone-tech continues to drive technological advancements. Here are some key milestones:

End of 2017: Greenstone-tech launched the first domestic high-speed laserbekleding equipment (powder-based), increasing the cladding speed from 0.5-1m/min to 3-30m/min, breaking the foreign monopoly on technology and laying the foundation for the rapid adoption of laserbekleding in China.

Subsequent improvements: The company developed a range of 6KW-20KW high-speed powder laserbekleding equipment, creating differentiated capabilities. The 6KW equipment is suitable for precision component repair, while the 10KW-20KW equipment meets the needs for high-volume, large-area, high-hardness, and wear-resistant coatings.

2024-2025: The introduction of 6KW-20KW internal and external wall high-speed laser cladding wire equipment successfully integrates wire technology into laserbekleding, filling a global industry gap. Internal wall equipment adapts to pipes with diameters ≥80mm, while external wall equipment, equipped with adjustable wire feed arms, significantly improves adaptability for complex components.

Core Advantages of Laser Cladding Wire Equipment

Greenstone-tech’s laser cladding wire equipment demonstrates significant competitive advantages in multiple dimensions:

Dual material compatibility: It supports both powder and wire cladding. By simply changing the feeding mechanism, it can switch between the two, effectively reducing the equipment investment cost for businesses.

Wide wire compatibility: It can adapt to conventional arc welding wires as well as copper, titanium, and aluminum alloy wires, meeting the needs of various industries.

High deposition efficiency: The maximum deposition efficiency reaches 8-10kg/h, far exceeding that of the powder-based equipment (2-5kg/h), greatly shortening the processing cycle for large-sized and large-area components.

Complex path adaptation: Featuring a center-feed wire design with no directional limitations, it can achieve 3D printing and other complex path processing.

Lower cost: The cost of wire is only 1/3 to 1/2 of the powder’s price, with 100% utilization, significantly reducing processing costs.

Strong stability: With high feeding precision, the cladding layer thickness error is ≤0.2mm, achieving processing results comparable to high-speed laser cladding powder technologie.

Applications and Potential of Laser Cladding Wire Technology

Combining real-world applications and user feedback, laser cladding wire technology has the potential to replace laser cladding powder technology in several scenarios, and in some cases, it is the preferred solution:

Internal wall cladding: It effectively solves the powder cladding problem of powder accumulation and smoke, ideal for processing internal walls of oil pipelines, acid and alkali transport pipes, and slurry pipes in thermal power plants.

Large-area coatings: For applications such as corrosion protection for the outer walls of chemical reactors and bridge supports, using stainless steel coatings, laser cladding wire reduces processing costs by 30%-50% compared to powder cladding technology.

Non-ferrous metal processing: Cladding with copper wire results in porosity ≤1% (powder cladding typically exceeds 5%), and cladding with titanium wire eliminates the risk of explosions and sparks, making it suitable for aerospace titanium alloy component processing.

Metal additive manufacturing: The 6KW-20KW equipment, paired with a six-axis robotic arm and positioner, can print complex metal components. It has already been deployed in the aerospace industry and research sectors.

Conclusie

The diversification of laserbekleding technology from “powder dominance” to “wire rise” represents the industry’s deep exploration of laser technology, material compatibility, cost control, and process efficiency. Greenstone-tech has broken the monopoly of Western industry standards by creatively using multi-beam technology, filling the gap for high-power laser cladding wire equipment globally. With the dual-technology route of “powder + wire,” it offers flexible solutions for various industries, retaining the precision advantages of powder-based laserbekleding while solving challenges related to non-ferrous metal processing and cost control.

Als laser cladding wire technology matures in applications such as internal wall cladding, large-area coatings, and additive manufacturing, its potential to replace traditional methods will continue to grow. In the future, this technology is expected to transform the laserbekleding industry from a “single-material choice” to a “full-scenario technology adaptation,” driving green and efficient upgrades in mechanical manufacturing, aerospace, and other fields. This will allow laserbekleding technology to play an even more significant role in laser (re)manufacturing.
