Laser Cladding Automatic Welding Machine

Laser cladding uses high-energy laser to irradiate the metal surface, causing the metal surface and the cladding material to interact and melt to form a layer with physical properties such as high hardness, good wear resistance, corrosion resistance, and oxidation resistance. The cladding process uses a cast iron platform base. The high-power laser runs fast and stably, and the size can be customized according to demand.

Description

The core components of laser cladding welding machine

Laser generator

Provides a high-energy-density laser beam (commonly fiber laser, CO laser, or semiconductor laser).

Power range: 500W to 10kW (adjusted depending on melt thickness and material requirements).

Powder Delivery System

Compact integrated touch screen, stable operation, and no powder blockage. Microcomputer-controlled powder flow rate with remote control. Air-carrying powder delivery allows for long-distance powder delivery with high precision. Optional dual-drum powder delivery is available to meet customer needs.

Cladding-specific laser head + motion control system

· Water-cooling ensures heat-free cladding even after extended periods. Multi-channel powder feeding and coaxial gas supply ensure uniform powder delivery and prevent oxidation of the cladding zone. Adjustable nozzles enable easy cladding of special-shaped products.

· Multi-axis robotic arms or CNC numerical control systems enable automated cladding of complex trajectories (e.g., curved surfaces and spiral paths).

· Compatible with automated production lines for unmanned operation.

Cooling and Protection System

A water cooling system prevents the laser from overheating.
A shielding gas (such as argon) prevents oxidation in the molten pool and improves the quality of the cladding layer.

Advantages of Laser Cladding

1. High-Precision Cladding
· Adjustable laser spot diameter (0.1-5mm), suitable for micron-level precision cladding (e.g., aircraft blade repair)
· Minimum heat-affected zone (HAZ), reducing substrate deformation.
2. Multi-layer/Gradient Cladding
· Layer-by-layer deposition of different materials (e.g., corrosion-resistant base layer, wear-resistant surface layer) creates a functionally gradient coating.
· Suitable for 3D printing of complex structures (e.g., special-shaped molds and customized parts)
3. High-Performance Cladding
· Customizable alloy layers with wear-, corrosion-, and high-temperature resistance (e.g., nickel-based, cobalt-based, tungsten carbide, etc.)
4. Low dilution rate (<5%)
· Minimal mixing between the cladding layer and the substrate, preserving the original properties of the cladding material (e.g., high hardness and corrosion resistance)
5. Environmentally Friendly
· No slag, low smoke, and some processes do not require shielding gas (e.g., some self-shielding powders)
6. Repair Capability
· Repairs worn or corroded parts (e.g., shafts and molds), extending their service life.

Laser Cladding Process Introduction

1. Coaxial Powder Feed Cladding: The laser beam is fed coaxially with the powder flow, making it suitable for complex curved surfaces (such as turbine blades).

2. Side-Axis Powder Feed Cladding: Powder is fed from the side, making it suitable for cladding large areas (such as roll repair).

3. High-Speed Cladding (HLC): Using ultra-high powder feed speeds (e.g., 100 m/min), cladding efficiency is increased by 3-5 times, making it suitable for mass production.

4. Hybrid Cladding (Laser + Arc): Combining the high precision of lasers with the high deposition rate of arcs, it is suitable for large structures (such as ship decks).
