Laser processing and manufacturing have developed rapidly in China in the past decade, and one of the important performances driving the market growth is the replacement of traditional processes by lasers. From the past silk screen printing and knife engraving to today's laser marking and engraving, from the past punching and blade cutting to today's laser cutting, from traditional chemical agents, pickling to today's laser cleaning, etc., are all major changes in technology. On the basis of environmental protection and green manufacturing, the process is more efficient, the output is larger, and the process effect is more beautiful. This is the technological progress brought by the laser, and it is also an inevitable trend of industrial technology development. The rapid rise of handheld laser welding machine In terms of welding, there has also been a change in technology, from ordinary electric welding and arc welding in the past to laser welding today. Laser welding based

 In the thin plate welding industry, the hand-held laser welding machine has become an emerging industrial technology loved by the market due to its advantages of simple operation, high efficiency, and smooth and beautiful welds. Hand-held laser welding machines are widely used, but many people want to ask what materials can be welded by handheld laser welding machine s? 1. Stainless steel The thermal expansion coefficient of stainless steel is high, and it is easy to overheat during welding. When the heat-affected area is slightly large, it will cause serious deformation problems, and the heat generated by the hand-held laser welding machine during the entire welding process is low. , coupled with the relatively low thermal conductivity, high energy absorption rate, and melting efficiency of stainless steel, a well-formed, smooth, and beautiful weld can be obtained after welding. 2. Carbon steel Ordinary carbon steel can be directly welded by hand-held laser welding, the effect is com

Once upon a time, we often see welders using spark-splashing manual welding equipment, but it is not an easy task to weld a workpiece with a beautiful weld. It is necessary to wear insulating shoes and heavy gloves while holding a Protective mask, while holding heavy welding tongs, unskilled people often let the electrode be sucked by the electrode. Advantages of handheld laser welding machine: Now, there is more advanced welding equipment - a handheld laser welding machine . Compared with traditional welding methods, what are the advantages of hand-held laser welding machines? 1. Simple operation: you can start welding without spending a lot of training costs. 2. Fast and efficient, with a wide range of processing: the laser welding machine has concentrated energy, high-efficiency, and high-speed welding, smooth and beautiful welds, and reduces subsequent grinding processes. 3. Wide range of weldable materials: stainless steel plate, iron plate, galvanized plate, aluminum plate, and o

 Although the handheld laser welding machine is very good welding equipment, mastering certain skills can help us use the hand-held laser welding machine better. Let us explain to you what the common welding methods of hand-held laser welding machines are. What are the welding methods commonly used in handheld laser welding machines? Laser welding can generally be divided into heat conduction type and deep penetration type welding, but there is also a new welding mode: the unstable phenomenon of sharp fluctuation of weld penetration under stable process conditions is called mode instability welding. After research, it is found that in the process of mode instability welding, the plasma is intermittently generated and extinguished, and the whole process is a random and random change of deep penetration welding and heat conduction welding, which can be seen from the welding seam forming. A characteristic of random changes in welding patterns. In the deep welding mode, the weld is wide a

As we all know, the laser has the characteristics of "good monochromaticity, high directivity, high coherence, and high brightness". Laser welding is also a process in which the light emitted by the laser is used. After optical processing, the laser beam is focused to generate a beam of huge energy, which is irradiated to the welding part of the material to be welded, and it is melted to form a permanent connection process. More than ten years ago, the main laser used for laser welding in China was the solid-state lamp pumping laser, which has large energy consumption and volume. To solve the shortcomings of its light path direction being difficult to change, fiber-optic transmission laser welding equipment was introduced. Then inspired by foreign handheld optical fiber transmission equipment, he produced his own handheld laser welding machine. This is the "first generation of handheld laser welding machine " in China. Due to the flexible transmission of optical fib

(1) The aspect ratio of height. The welding is deep and narrow, and the welding is bright and beautiful. (2) Minimal hot typing. Because of the high power, the whole melting process is very fast, the heat of the typed product workpiece is very low, the welding speed is faster, the thermal deformation is small, and the thermal damage is small. (3) High compactness. During the whole process of welding, the molten pool is continuously stirred, and the vapor is easy to come out, resulting in the transformation into penetration welding without vent holes. The high cooling efficiency after welding also makes it easy to micro-optimize the welding arrangement, and the welding compressive strength, ductility and comprehensive performance are high. (4) Solid welding. High temperature pyrogen and complete digestion and absorption of two components of non-metallic materials lead to purification effect, reduce residue components, change the specification of impurities and their distribution in fusi
