    Apr 09, 2025 A Brief Analysis of the Influence of Scanning Speed on the Laser Cladding Performance of 45 Steel Surface
    Introduction: Ordinary 45 steel can no longer meet the requirements for high strength, high hardness, wear resistance, corrosion resistance, and other performance characteristics. This has led to the development of surface modification technologies to improve the material surface properties. Traditional industrial cleaning methods include various types of cleaning, mostly relying on chemical agents and mechanical methods. In the context of increasingly strict environmental protection regulations in China and growing awareness of environmental and safety issues, the range of chemical agents available for industrial cleaning is becoming more limited. Therefore, it is essential to consider cleaner and non-damaging cleaning methods. Laser cleaning, characterized by its non-abrasive, non-contact, and non-thermal effects, and its suitability for a variety of materials, is considered the most reliable and effective solution. Moreover, laser cleaning can solve problems that traditional cleaning methods cannot address. Laser cladding technology has been widely adopted. 5 steel, as one of the commonly used steels in the machinery industry, has a wide range of applications. Laser surface strengthening utilizes the plasma shock waves generated by a strong laser beam to enhance the fatigue resistance, wear resistance, and corrosion resistance of metal materials. It offers several advantages, such as non-contact, no heat-affected zone, strong controllability, and significant strengthening effects. However, as technology advances, the demands for material applications continue to increase. Ordinary 45 steel can no longer meet the requirements for high strength, high hardness, wear resistance, and corrosion resistance. As a result, methods using surface modification technologies to improve material surface performance have been developed. Laser cladding, with its concentrated heat source and high efficiency, has been widely adopted in practical production. This paper investigates the effect of scanning speed on the surface structure and performance of a Ni-based composite coating prepared on the surface of 45 steel using laser cladding. Materials and Methods: Several 200mm×100mm×6mm flat pieces of 45 steel were selected as the base material. The surface of the 45 steel to be cladded was polished with sandpaper to remove oil and rust, and then alcohol was applied to the surface. Traditional cleaning methods in the industry include various approaches, primarily relying on chemical agents and mechanical methods.

  • Key considerations for laser welding of dissimilar materials
    Jan 06, 2025 Key considerations for laser welding of dissimilar materials
    Several key factors need to be considered when welding dissimilar materials: A. Material matching and compatibility When selecting dissimilar materials for welding, compatibility must be considered, especially in terms of chemical composition, melting temperature and thermal expansion coefficient. These factors directly affect the stability and quality of the weld. 1. Chemical composition compatibility: Differences in the chemical composition of different materials may lead to the formation of unfavorable compounds or oxides during welding, thereby affecting the quality of the weld. Appropriate filler materials need to be selected to avoid these adverse reactions. 2. Melting temperature matching: Differences in the melting temperatures of dissimilar materials will lead to uneven heat distribution during welding, affecting the welding effect. Controlling the temperature of the welding heat source to ensure that both materials can melt smoothly is the key. 3. Thermal expansion coefficient difference: Different thermal expansion coefficients between materials will generate stress during welding and increase the risk of cracks. This problem can be alleviated by optimizing the welding design and appropriate heat treatment. 4. Alloy filler material: For materials that are difficult to be compatible, the use of alloy filler materials can help improve the welding effect and enhance the strength and durability of the weld. 5. Welding process selection: Selecting a suitable welding process, such as laser welding, TIG welding, etc., can effectively reduce the incompatibility between materials and ensure the stability of the welding process. By reasonably selecting alloy filler materials, welding methods, and controlling heat input, the stability and quality of dissimilar material welding can be effectively improved. B. Optimal laser parameters In laser welding, selecting the correct laser parameters is the key to ensuring welding quality, especially when welding dissimilar materials. The following is a brief introduction to laser parameters: 1. Laser power: Laser power directly affects the depth and width of the weld. When the power is too low, it may not be able to achieve sufficient melting depth, resulting in incomplete welding; too high power may cause overheating, burn-through, or material deformation. Dissimilar materials have different thermal conductivity and melting temperatures, and the laser power needs to be precisely adjusted to ensure uniform temperature in the weld area and avoid defects. 2. Pulse frequency: The pulse frequency affects the heating and cooling speed of laser welding. Higher pulse frequencies are suitable for thinner materials, while lower frequencies are suitable for thicker materials. When welding dissimilar materials, the pulse frequency needs to balance the difference in thermal conductivity of the two materials to avoid cracks or weakened joints due to too fast or too slow cooling. 3. Scanning speed: The scanning speed aff...

  • How can laser cleaning machines benefit the food industry?
    Jan 02, 2025 How can laser cleaning machines benefit the food industry?
    Laser cleaning technology ensures that most of the dirt evaporates and the remaining residues fall loose. Not only does the laser cleaning machine clean more thoroughly than traditional methods, but the heat generated by the laser beam also has antibacterial properties, which can effectively remove bacteria and microorganisms from the surface of the substrate. In addition, laser cleaning machines reduce harm to the environment and human health, making them an indispensable innovative technology in the development of the food industry. Today, we will explore some basic knowledge about laser cleaning machines. In addition, we will also discuss the application of laser cleaning machines in the food industry. We hope that this article will help you choose a laser cleaning machine that suits your needs. What is laser cleaning technology? Laser cleaning technology uses high-intensity laser beams to remove oil, rust, oxides and other residues from the surface of metals and other materials. Thermal decomposition: When the laser beam is irradiated to the surface of the target material, the temperature rises rapidly due to the energy of the beam, accelerating the heating and evaporation of the contaminants. This process is similar to breaking down dirt with high temperatures and is particularly suitable for removing stubborn grease and coatings. Photolysis: High-energy laser photons interact with contaminant molecules and break molecular bonds. This photolysis effectively removes complex chemical contaminants such as paint and oxide layers. What are the benefits of laser deep cleaning? 1. Extend equipment life One of the main advantages of laser cleaning machines is the contactless cleaning process. Contactless means that when dealing with grease and other contaminants, no mechanical tools are required to remove them, and no chemical cleaners or abrasive grinding is required, because the cleaning medium is a high-energy laser beam. The laser beam only acts on surface contaminants without applying friction or pressure to the substrate. Therefore, using a laser cleaning machine will not cause wear and tear on your production equipment. 2. Achieve precise cleaning The laser beam in the laser cleaning machine can be focused into an extremely small spot with a diameter as small as a few microns. This concentrated energy enables the laser cleaning machine to work in very small areas, such as grooves and narrow spaces that are difficult to clean. In addition, the laser cleaning machine can adjust the pulse width and frequency of the laser according to your cleaning needs. For example, short pulse widths are suitable for removing thin layers of contaminants, while high frequencies can be used for large-scale cleaning. Finally, the laser power can be precisely adjusted according to the complexity of the cleaning task. Lower power is suitable for removing light dirt, while higher power can be used to remove stubborn oxide layers or rust. 3. More hygienic and safer I...

  • Differences between continuous and pulsed laser cleaning machines
    Dec 20, 2024 Differences between continuous and pulsed laser cleaning machines
    Continuous and pulsed laser cleaning machines are two types of lasers for laser cleaning machines. This article will focus on the working principle, laser characteristics, specific applications, etc. of pulsed laser cleaning machines and continuous laser cleaning machines. At the same time, the differences between the two will be analyzed in depth. At the end of the article, we will give professional laser cleaning machine purchase guidance. 1. What is a pulsed laser cleaning machine? 1.1 Working principle of pulsed laser cleaning machine To understand what a pulsed laser cleaning machine is, you must first understand what a pulsed laser is. Pulse laser can be understood as: every short time interval, the laser will be concentrated once, and the light will be continuously emitted repeatedly, so the pulsed light has a prominent time interval characteristic. Pulse lasers can achieve high peak power precision laser cleaning tasks by adjusting the pulse width and pulse frequency. 1.2 Two output beam modes of pulsed laser cleaning machines: single mode and multi-mode Pulse laser cleaning machines are divided into single-mode pulsed laser cleaning machines and multi-mode pulsed laser cleaning machines according to the beam quality, spot size, energy distribution, and output power. Single-mode pulse laser beam quality is higher, M² value can be close to 1, the spot is smaller, the laser output energy is more concentrated, and the energy distribution of single-mode pulse laser is Gaussian distribution, high in the middle and low on both sides. These characteristics make the beam of single-mode pulse laser sharper, like a needle tip, and more effective in removing pollutants such as oil, rust, etc. However, the fiber core used by single-mode laser is thinner, generally about 4-10 microns, so the output power of single-mode pulse laser is lower than that of multi-mode pulse laser. Multi-mode pulse laser has larger spot size, wider beam distribution, and flat-top energy distribution, like a small flat-top house. When performing laser cleaning tasks, it sweeps back and forth like a wide broom. Compared with single-mode pulse laser, multi-mode pulse laser has softer beam. In addition, multi-mode pulse laser has greater output power, so the cleaning efficiency is faster. Multi-mode pulse laser has high output power and large spot size, which is the best choice for cleaning large areas or thick layers. 1.3 Features of pulse laser cleaning machine: High peak power: The pulse laser cleaning machine releases high energy in the form of short pulses, and can release high energy in a very short time, so it has a high peak power. When performing laser cleaning tasks, not only can the higher laser energy be used to remove oxide layers, oil stains, rust, etc., but the thermal impact on the substrate is also minimal and will not cause damage. Adjustable pulse width: Our pulse laser cleaning machines all use MOPA (Master Oscillator Power Amplifier) lasers, so the pulse wi...

  • Laser VS sandblasting VS high-pressure water gun rust removal, which one is more powerful?
    Dec 10, 2024 Laser VS sandblasting VS high-pressure water gun rust removal, which one is more powerful?
    Laser rust removal The principle of laser rust removal is laser cleaning. The process of pulsed Nd:YAG laser cleaning depends on the characteristics of the light pulse generated by the laser, based on the photophysical reaction caused by the interaction between the high-intensity beam, short-pulse laser and the contamination layer. Its physical principle can be summarized as follows: 1. The beam emitted by the laser is absorbed by the contamination layer on the surface to be treated. 2. The absorption of large energy forms a rapidly expanding plasma (highly ionized unstable gas), generating shock waves. 3. The shock wave breaks the contaminants into fragments and removes them. 4. The width of the light pulse must be short enough to avoid heat accumulation that damages the treated surface. 5. Experiments show that when there is an oxide on the metal surface, plasma is generated on the metal surface. Plasma is only generated when the energy density is higher than a threshold, which depends on the contamination layer or oxide layer to be removed. This threshold effect is very important for effective cleaning while ensuring the safety of the substrate material. There is also a second threshold for the appearance of plasma. If the energy density exceeds this threshold, the cleaning effect will be affected. In order to effectively clean the substrate material while ensuring its safety, the laser parameters must be adjusted according to the situation so that the energy density of the light pulse is strictly between the two thresholds. Each laser pulse removes a certain thickness of the contamination layer. If the contamination layer is thick, multiple pulses are required for cleaning. The number of pulses required to clean the surface depends on the degree of surface contamination. An important result of the two thresholds is the self-control of cleaning. Light pulses with energy density higher than the first threshold will continue to remove contaminants until they reach the substrate material. However, because their energy density is lower than the damage threshold of the substrate material, the substrate will not be damaged. Sandblasting Rust Removal The principles of sandblasting and high-pressure water gun rust removal are actually similar. The main purpose is to spray corundum to impact the surface to achieve the purpose of rust removal. Sandblasting process: It uses compressed gas to spray material (commonly used spray materials include copper ore sand, quartz sand, corundum, iron sand, Hainan sand, etc.) onto the surface of the workpiece in a high-speed air pressure manner. Under the impact and cutting of the spray material on the surface of the workpiece, the surface is given a certain degree of cleanliness (such as rust removal). Rust removal with high-pressure water gun High-pressure water gun sprays water and sand together. By combining the lubrication of water and the grinding force of sand, it can effectively remove rust and dirt, while re...
