Portable Laser Intelligent Additive and Subtractive Repair Equipment
Equipment Background
In the hydropower, wind power, chemical, metallurgical and mold industries, the on-site rapid repair of high-end equipment has always been the focus of attention. Equipment parts such as turbine seat rings, wind turbine shafts, pipeline networks, rolling mill arches, engine blades, etc., often face problems such as wear, corrosion, and fatigue under the influence of long-term high-intensity operation and extreme environments. Laser cladding technology, as a technology for additive manufacturing of parts, has been widely used in the field of repair. The defective parts are repaired by laser cladding, and the formed cladding layer has the advantages of low dilution rate, dense structure, and good bonding with the matrix.
In the face of the repair needs of the above-mentioned high-end equipment, traditional laser additive equipment has large volume and weight, difficult on-site installation and layout, limited accessible space, and is difficult to adapt to the complex on-site environment. Manual operation is cumbersome and the system automation is not high, which limits the repair efficiency and accuracy. Now a small intelligent equipment integrating additive and subtractive processing is used. The research on key technologies of laser additive and subtractive composite manufacturing based on collaborative robots can not only solve the problems of existing equipment, but also promote the entire repair process to develop in a more efficient, flexible and intelligent direction, providing more innovative and feasible solutions for the on-site rapid repair of high-end equipment.
Equipment advantages
- Portable structure design: The equipment adopts a modular design, each module has independent functions, and can be disassembled and assembled according to different usage scenarios;
- Visual adaptive cladding system: It can perform three-dimensional positioning and defect extraction, and combined with the Huirui slicing system, it can achieve 0.1mm precision cladding printing;
- Diversified teaching schemes: Push-pull, vision, and light pen are three major teaching methods to meet personalized needs;
- Additive repair path process library: For typical surface filling path planning, formulate path generation strategies, and establish a parametric standard path library that matches the material;

Equipment function display
- Lightweight and portable
The equipment adopts a modular design. Each module has independent functions and can be disassembled and assembled according to different usage scenarios. The module is lightweight and can be easily deployed by 1-2 people at the work site. The robot is fixed by magnetic suction and can be installed upright, sideways, or upside down.
- Drag-and-drop teaching experiment
The collaborative robot was introduced into the laser cladding industry for the first time. The drag-and-drop teaching function is combined with the cladding target: 20*20mm square. After cladding: the error is within 1mm. This method can quickly frame the cladding area and save teaching time.
- Visual adaptive repair
3.1 Blade repair
Use the self-developed visual adaptive cladding system and process path library to carry out blade extension and local defect repair. The blade is accurately positioned, there is almost no light leakage at the edge, and the cladding effect is good.
3.2 Engine mold core insert
Use the self-developed visual adaptive cladding system and process path library to extend the size of the mold core insert. Accurate positioning, good molding effect, cladding height of 25mm without collapse.
3.3 Defect contour recognition
Select the detection target (triangle, rectangle, square, polygon, circle, ellipse), the system extracts features based on the current screen image and automatically generates the cladding path.
- Additive and subtractive integrated function
Flip the tool head to switch between laser additive and force-controlled subtractive. Realize the integration of “drilling pre-processing – cladding processing – polishing post-processing” to simplify process switching time. Constant contact force control, good system stability.
Application Cases
- Wind power equipment
Demand: Regular inspection and repair of mechanical shafts (bearings)
Pain points: The traditional repair method removes the rotor shaft from the cabin, which is expensive to use a high-altitude crane, and the entire processing cycle of hoisting + repair + reinstallation is long; the online repair method is used, and it is inconvenient to hoist large maintenance equipment due to the high working position.
Matching degree: high. The portable repair equipment has a compact structure, is easy to hoist, is convenient and quick to arrange, and has strong adaptability to online repair.
- Hydropower Station
Demand: Repair of wear and deformation of hydropower unit seat ring; repair of cavitation in turbine runner chamber.
Pain point: The large-scale repair equipment on site for hydropower seat ring remains unchanged; the current repair method is mostly welding repair, which has a short life and leads to repeated surfacing.
Matching degree: high. The portable repair equipment has a compact structure, is easy to move, and the magnetic structure is easy to install and fix.
- Rolling mill arch repair
Requirement: Repair the failed working surface of the arch
Pain points: The rolling mill frame is large in size and weight, with many auxiliary pipelines, etc., which makes disassembly, installation, and transportation complicated. In addition, there is a time limit for overhaul; the on-site working space is small, and large equipment cannot be moved.
Matching degree: high. The portable repair equipment has a compact structure, is easy to move, and the magnetic suction structure is easy to install and fix.
