Analysis of various types of laser welding machines

Laiser Laser has been focusing on the laser industry for more than 10 years. In order to meet the different needs of customers for laser welding machines, Laisai Laser has developed different types of laser welding machines: advertising word welding machine, mold welding machine, jewelry welding machine, fiber conduction welding machine, multi-function welding machine, to meet the various needs of various industries in an all-round way. The following are the advantages of different types of laser welding machines.

Advertising word laser welding machine:

Advertising word welding machine, also known as advertising word laser welding machine, uses high-energy pulsed laser to weld objects. The discharge of the laser power supply causes the xenon lamp pulse to generate a light wave of a certain frequency and pulse width, and radiates it into the crystal, that is, the YAG crystal, through the focusing cavity. The crystal emits a 1064-nanometer pulsed laser after resonance, and then expands, reflects, and focuses it for welding.

Advantages:

1. Good effect: no blackening or deformation after welding, firm, no grinding, and high precision.

2. High efficiency: the equipment is ready to use, easy to operate, and the welding speed is 8-10 times that of traditional processes. Low cost: no consumables, no surface treatment, and no high-paid professionals are required. Ordinary workers can learn and master it immediately, the operating environment is comfortable, and it is easy to weld complex fonts.

3. High stability: imported laser from the UK, with a service life of 8-10 years, stable performance, high power, and xenon lamp light output times of more than 8 million times. Continuous operation for 24 hours.

4. Flexible optical path: can move up and down, and the laser head can rotate 360 degrees. The extended optical path is used, which is suitable for welding various fonts and types. Standard models and dual optical paths can be selected. Small characters are welded with hard optical paths, and large characters are welded with 5-meter-long optical fiber welding heads.

Mold laser welding machine:

Standard welding machine is also called mold welding machine, laser welding machine, laser welding machine, laser cold welding machine, laser argon welding machine, laser welding machine, etc. As a new type of welding method, the standard welding method is mainly aimed at thin-walled parts and precision parts, and can realize spot welding, butt welding, lap welding, sealing welding, tailoring welding, penetration welding, filling welding, seam welding, airtight welding, etc., and can adapt to various welding paths. Higher depth ratio, smaller width, smaller heat-affected zone, smaller deformation, fast welding speed, smooth appearance, no or simple treatment after welding, high quality, no pores, precise control, small focus, accurate positioning, and easy automation.

Advantages: Compared with other welding methods, the welding point is small; the heat-affected zone is small, the thin-walled metal does not deform, the welding speed is fast, and the positioning accuracy is high; there is no need to use self-melting welding, the weld strength is high, no pollution, no holes, firm and beautiful. Laser welding of electronic components will not damage the sealing ring and integrated circuit; it can improve the appearance and performance stability of the product and enhance the competitiveness of the product.

Jewelry laser welding machine:

Laser spot welding is the use of high-energy laser pulses to locally heat a small area of the material. The energy of the laser radiation diffuses into the material through heat conduction, and the molten material forms a specific molten pool. The laser spot welder (jewelry spot welder) can weld the same or different materials.

Fiber optic transmission welding machine:

Fiber optic transmission laser welding machine is a laser welding equipment that couples high-energy laser beams into optical fibers, transmits them over long distances, collimates them into parallel light through a collimator, and then focuses on the workpiece for welding. For parts that are difficult to weld, flexible sensing non-contact welding is used, which has greater flexibility. Using a fiber optic transmission laser welding machine, time and energy splitting can be achieved, and multiple beams can be processed simultaneously, making welding more precise.

Advantages:

1. High stability, high reliability, 24-hour stable operation.

2. Optional CCD camera monitoring system for easy observation and precise positioning.

3. Even energy distribution of welding points, better welding characteristics.

4. It is suitable for various complex welds, spot welding of various equipment and seam welding of thin plates within 1 mm.

Multi-function laser welding machine:

Use high-energy laser pulses to locally heat a tiny area of the material, and the energy of the laser radiation diffuses into the material through heat conduction, and the molten material forms a specific molten pool. This new welding method is mainly based on thin-walled materials and welds precision parts. It can realize a variety of welding methods such as spot welding, butt welding, lap welding, and sealing. It has a high aspect ratio, a small welding width, a small heat-affected zone, small deformation, a fast welding speed, a smooth and beautiful welding, no or no treatment after welding, high welding quality, no pores, controllable, small focus, accurate positioning, and easy to realize automation.

Advantages:

1. High depth-to-width ratio. The weld is deep and narrow, bright and beautiful.

2. Due to high power density and fast melting range, low heat input to the workpiece, fast welding speed, small thermal deformation and small heat affected zone.

3. High density. During the welding process, the molten pool is constantly stirred, gas escapes, and a non-porous weld is formed. The high cooling rate after welding is easy to refine the welding structure, and the welding strength, toughness and comprehensive performance are high.

4. Strengthening welding. The full absorption of high-temperature heat source and non-metallic components produces a purification effect, reduces the impurity content, changes the mixed size and distribution of the molten pool, does not require electrodes and filler wires during welding, has little pollution in the molten area, and the welding strength and toughness are equivalent to the parent metal.

5. Precise control. Due to the small focus point, the weld can be positioned with high precision, the beam is easy to transmit and control, and there is no need to frequently replace the welding torch and nozzle, which significantly reduces the downtime auxiliary time and has high production efficiency. There is no inertia, and emergency stop and restart can also be performed at high speed. Automatic control of beam movement technology can weld complex components.

6. Non-contact and atmospheric environment welding. Because the energy comes from the laser, there is no physical contact with the workpiece, so no force is applied to the workpiece. Magnetism and air have no effect on the laser.

7. Due to the low average heat input and high processing accuracy, the reprocessing cost can be reduced. At the same time, the low operating cost of laser welding can reduce the cost of the workpiece.
