With the continuous development of industrial technology, laser cladding technology, as an advanced surface modification technology, has been widely used in the field of material surface strengthening, repair and remanufacturing. As a kind of laser cladding technology, broadband laser cladding technology has the advantages of high energy beam density, high heating efficiency and high cladding quality, and has become a research hotspot in the field of laser cladding.
Composition of broadband laser cladding equipment
Broadband laser cladding equipment is mainly composed of laser, optical path system, control system, powder feeding system, processing platform and other parts. The laser is the core part of the device, and its output power and wavelength determine the thickness and composition of the cladding layer. The optical path system is responsible for transmitting the laser beam to the processing area, usually using optical components such as mirrors and focusing lenses. The control system is responsible for the precise control of each part of the equipment to ensure the stability and consistency of the cladding process. The powder feeding system is responsible for evenly transporting the cladding material to the processing area to ensure the quality and uniformity of the cladding layer. The machining platform is responsible for loading the workpiece, which can be controlled automatically or manually to realize the rapid positioning and processing of the workpiece.
Working principle of broadband laser cladding equipment
The working principle of broadband laser cladding equipment is to use high energy broadband laser beam to melt the cladding material quickly and form a dense cladding layer on the surface of the workpiece. In the process of cladding, the laser beam scans the surface of the workpiece at a certain speed, and the cladding material is uniformly sent to the area irradiated by the laser beam through the powder feeding system, and it melts rapidly under the action of the laser. The molten material is metallurgically combined with the substrate to form a cladding layer with excellent properties. The thickness, composition and microstructure of the cladding layer can be controlled by adjusting the laser power, scanning speed and powder feeding amount.
Characteristics of broadband laser cladding equipment
1. High energy beam density: Broadband laser output power is high, high energy concentration, can quickly heat and melt cladding materials in a short time.
2. High heating efficiency: Because the wavelength of the broadband laser is short, its energy is easily absorbed by the cladding material, improving the heating efficiency and shortening the processing time.
3. High cladding quality: Broadband laser cladding equipment adopts advanced control system and light path system to ensure the stability and uniformity of the laser beam, and improve the density and bonding strength of the cladding layer.
4. Wide range of applications: broadband laser cladding equipment can be used for surface strengthening, repair and remanufacturing of a variety of materials, such as steel, non-ferrous metals, ceramics and so on.
5. Environmental protection and energy saving: compared with the traditional heat treatment and surface treatment technology, broadband laser cladding technology has the advantages of high efficiency, energy saving and no pollution.
