The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and fine parts. It can realize spot welding, butt welding, stitch welding, sealed welding, etc., with high aspect ratio, small weld width, and small heat affected zone. Small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple processing after welding, high welding seam quality, no air holes, accurate control, small focus spot, high positioning accuracy, and easy to realize automation. Compared with traditional welding methods, steel laser welding machine has the following advantages：
1. Simple operation: welding can be done by hand, no need to spend high training costs.
2. Fast and efficient, wide range of processing: the laser welding machine has concentrated energy, high-efficiency and high-speed welding, smooth welding seam, reducing subsequent polishing procedures.
3. Wide welding materials: stainless steel plate, iron plate, galvanized sheet, aluminum plate and other metal materials can be welded.
4. Break through the limitations of the shape of the workpiece and the processing environment: small solder joint, small heat affected area: no need to set up the welding table, small space, flexible processing, fast welding speed, can be moved for long-distance operation, not limited by the environment and space.
5. High performance-price ratio: Manual hand-held laser welding machine can not only perform hand-held laser welding operations, but also engage in high-precision welding and repairing of molds through the later erection platform. It is the preferred cost-effective welding production equipment for more small-scale manufacturers.
The working principle of laser welding is to use high-energy laser pulses to heat a small area of the material. High-temperature energy diffuses from the surface of the material to the inside, and forms a specific molten pool after melting. The material in the whole process is high temperature, so how should we use laser welding machine safely?
1. During the operation, if there is an emergency, such as water leakage or abnormal laser sound, you need to immediately press the emergency stop button and quickly cut off the power supply.
2. The external circulating water switch of laser welding must be turned on before operation. Because the laser system adopts water cooling method, the laser power supply adopts air cooling method. If the cooling system fails, it is strictly forbidden to start working.
3. It is strictly prohibited to touch all the circuit components in the machine when working. When the laser welding machine is working, the circuit is in the state of high voltage and strong current. The operation of the machine is prohibited without training.
4. It is strictly prohibited to use the eye scanning laser directly when the laser is working in order to avoid eye injury. Do not use external equipment to reflect the laser when the laser is working.
5. Do not disassemble any parts of the machine at will, do not weld when the safety door is opened, and do not point the laser head at the parts of the equipment.
6. Do not place flammable and explosive materials where the laser light path or laser beam can be irradiated to avoid fire and explosion.
Steel laser welding machine is a new generation of laser welding equipment, belongs to the non-contact welding, the operation process does not need pressure, its working principle is the high energy intensity of the laser beam directly irradiated on the surface of the material, through the laser and material interaction, so that the material internal melting, and then form a weld. Handheld fiber laser welding machine to fill the laser equipment industry hand-held welding gap, overturn the traditional laser welding machine working mode, using the hand-held instead of the previous fixed light path, flexible and convenient, long welding distance, also makes the laser welding in the outdoor operation becomes possible.
