Manual Laser Welding

Laser welding is the use of high-energy laser pulses to localize the heating of the material in a tiny area, the energy of the laser radiation spreads to the interior of the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, which can realize spot welding, butt welding, stack welding, sealing welding, etc. It has fast welding speed, flat and beautiful weld, no need to deal with it after welding or only simple treatment, high quality weld, no air holes, can be accurately controlled, small focusing spot, high positioning accuracy, and easy to realize automation.

Features of Manual laser welding


1. The whole machine has an integrated structure design, the equipment occupies a small space, and is equipped with extra-large swivel casters, making it easy to carry and transport.

2. Comes standard with a variety of welding contact tips to meet a variety of welding needs and can achieve high-precision welding. The welds are small, beautiful and firm, and do not require polishing.

3. The electronic control area is equipped with a cooling fan as standard, which effectively improves the welding stability in high-temperature environments.

5. With visual instruments and water injection ports, the use process can be observed at any time. At the same time, a touch screen control panel is used to make modification of process parameters more intuitive and convenient.

4. The system can store a variety of different process parameters, which can be switched at any time through the touch screen according to processing needs, significantly reducing

5. Use infrared positioning for welding head position calibration and position verification during welding to ensure a more beautiful weld.

6. Has a variety of security alarm functions. The trigger switch is activated only when the soldering copper tip touches the metal and the safety clip clamps the metal plate. After the welding copper nozzle takes out the workpiece, the light will be automatically locked. The safety of the machine is very high, ensuring the absolute safety of the operator when working.

Advantages of Manual laser welding


1. The handheld laser welding head is light and flexible, easy to operate, and can meet welding at various angles and positions.

2. Using laser fiber for transmission, it has a long service life, fast welding speed and less consumables.

3. The operation is simple, no professional welder is required, ordinary people can operate it, no training is required, and the requirements for personnel are not high.

4. Handheld laser welding has a high aspect ratio, small weld width, small heat-affected area, small deformation and fast welding speed.

5. The weld is smooth and beautiful. No treatment is required or only simple treatment is required after welding, which reduces the subsequent grinding process and saves time and cost.

6. The weld is of high quality and has no pores, which can reduce and optimize impurities in the base metal. The strength and toughness of the weld is at least equal to or even exceeds that of the base metal.

7. The focused light spot is small, can be accurately controlled, and can be positioned with high precision, making it easy to realize automation.

8. Can realize welding between certain dissimilar materials.

9. Can realize spot welding, butt welding, stack seal welding, etc.

Use of laser welding machine


With the continuous development of laser welding technology, laser welding machines are becoming more and more widely used.


● Welding: The main welding objects of laser welding machines are metals, such as stainless steel, copper, aluminum, gold, silver, titanium, nickel, tin, chromium, niobium, carbon steel, mold steel, galvanized sheets, etc. It is suitable for flat, straight, Arc and arbitrary shape welding, welding work can be carried out from multiple angles to meet users' personalized welding needs.

● Cutting: Welding and cutting are often inseparable. Laser welding machines combine the functions of the two. Laser welding machines can be used to laser cut metal materials, such as copper plates, aluminum plates, stainless steel plates, carbon steel plates, galvanized plates, etc. Meet the cutting needs of conventional thin plates.

● Weld bead cleaning: It can effectively remove oxides, welding slag, oil, dust and other impurities produced during the welding process, making the weld surface clean. This not only helps improve the quality of the weld, but also enhances its strength and appearance. Laser cleaning is highly precise and controllable, thoroughly cleaning the weld surface without damaging the base material.
