Automated Robotic
Laser Cladding Machine
for Complex Components
6-axis robotic laser cladding workstation integrating fiber laser, cladding head, automatic powder feeder, positioner and PLC control -- for precision repair, hardfacing, surface strengthening and batch remanufacturing.
What Is an Automated
Robotic Laser Cladding Machine?
An automated robotic laser cladding machine is a complete surface repair and hardfacing workstation that uses a robot-controlled laser cladding head to deposit alloy powder onto the surface of a metal workpiece.
During the process, the laser beam melts the alloy powder and a thin layer of the substrate surface. After solidification, the coating forms a dense metallurgical bond with the base material -- improving wear resistance, corrosion resistance, high-temperature performance, surface hardness and service life.
The robot provides flexible multi-axis motion, while the positioner and fixture keep the workpiece in the correct orientation. This allows the system to process complex surfaces, curved parts, inclined surfaces and repeatable batch components more effectively than manual repair methods.
Why Use a Robot for Laser Cladding?
A robotic system delivers flexibility, repeatability and automation that manual welding repair and fixed cladding systems cannot match for complex industrial components.
Follow complex cladding paths on curved surfaces, irregular components, internal corners, edges and multi-angle repair zones.
Adjust the cladding head angle in real time. Combined with a positioner, maintain a stable cladding posture on difficult surfaces.
Once programmed, the same path and parameters can be reused for similar parts -- improving consistency for batch repair and remanufacturing.
Standardize motion, powder feeding and laser power. Reduce variation caused by individual operator experience.
Integrate fixtures, positioners, loading systems, safety enclosure, fume extraction and process monitoring into a stable repair line.
Reduce direct manual exposure to heat, powder and fumes. Equip with safety enclosure, interlock and fume extraction.
Eight Engineering Advantages of HALDEN Robotic Laser Cladding
Focused laser beam allows precise control of coating width, thickness and heat input -- ideal for local repair of high-value components.
Less heat introduced into the workpiece reduces the heat affected zone and helps control deformation on precision parts.
Cladding fuses with the base material, providing stronger adhesion than conventional coatings and resisting peeling under heavy-duty service.
Powder feed rate adjustable per material type, coating thickness and process speed -- single or dual hopper available.
Nickel, cobalt, iron, stainless steel and tungsten carbide composite powders -- selected per wear, corrosion, temperature and hardness need.
Coordinate with rotary or double-axis positioner for accessibility and stable cladding posture on shafts, rolls and piston heads.
Save and reuse robot paths, laser power, powder feed rate, travel speed and recipes -- scale from sample to batch production.
Automated operation reduces exposure to heat, powder, arc and fumes. Configurable safety enclosure, interlock and fume extraction.

Robotic laser cladding is recommended when the workpiece requires complex movement, multi-angle surface access, repeatable batch processing or integration into an automated repair production line.
Robotic Laser Cladding vs Traditional Methods

| Electroplating | Environmental concerns and limited heavy-duty repair ability | Cleaner process and functional alloy coating options |
| Complete Replacement | High spare part cost and longer downtime | Repair worn surfaces and extend component service life |
| Manual Grinding & Rework | Removes damage but does not improve surface performance | Restores dimensions and improves wear/corrosion resistance |
