Laser welding machine

Laser welding machine is a kind of mechanical equipment widely used in industrial production. It is a thermal processing process that uses a laser beam as a heat source. The Laser welding machine has many advantages. The laser focus of the laser beam is small, the power density is high, and it can weld some alloy materials with high melting point and high strength. Laser welding machines can often be divided into laser mold welding machines, automatic Laser welding machines, jewelry Laser welding machines, etc. according to their working methods. Learn more about the Laser welding machine below.

1. What is a Laser welding machine?

Laser welding machine is also often called Laser welding machine, energy negative feedback Laser welding machine, Laser welding machine, Laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc. It is used for material processing laser welding. machine.

Second, the working principle of Laser welding machine

Laser welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through thermal conduction, and the material is melted to form a specific molten pool. Laser welding machine is a new type of welding method, mainly for the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, stitch welding, sealing welding, etc.

3. Types of Laser welding machines

1. According to its working method, it can often be divided into laser mold welding machine (manual laser welding equipment), automatic Laser welding machine, jewelry Laser welding machine, laser spot welding machine, optical fiber transmission Laser welding machine, galvanometer welding machine, hand-held Welding machines, etc., special laser welding equipment includes sensor welding machine, silicon steel sheet laser welding equipment, keyboard laser welding equipment.

2. According to the weldable graphics, there are points, straight lines, circles, squares or any plane graphics drawn by AUTOCAD software.

Fourth, the advantages of Laser welding machine

1. Fast speed, large depth and small deformation.

2. It can be welded at room temperature or under special conditions, and the welding equipment is simple. For example, when a laser passes through an electromagnetic field, the beam will not be deflected; the laser can be welded in vacuum, air, and a certain gas environment, and can be welded through glass or materials that are transparent to the beam.

3. It can weld refractory materials such as titanium, quartz, etc., and can weld different materials with good effect.

4. After the laser is focused, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1, and the maximum can reach 10:1.

5. Micro welding can be carried out. After the laser beam is focused, a small spot can be obtained, and it can be accurately positioned, which can be applied to the group welding of micro and small workpieces in mass automatic production.

6. It can weld hard-to-reach parts, and implement non-contact long-distance welding, which has great flexibility. Especially in recent years, optical fiber transmission technology has been adopted in YAG laser processing technology, so that laser welding technology has been widely promoted and applied.

7. The laser beam is easy to realize beam splitting according to time and space, and can carry out multi-beam simultaneous processing and multi-station processing, which provides conditions for more precise welding.
