Handheld laser welding machines have become an indispensable tool in the modern manufacturing and maintenance industry due to their advantages such as high efficiency, welding quality, portability and versatility. In this article, we have made some relevant tips to help you choose a hand laser welder that suits your needs.
1. Is the hand laser welder useful?
Handheld laser welding machines are very useful in many application scenarios.
Handheld laser welding machines improve the welding defects that occur in the traditional welding process, the welds are smooth and beautiful, and the subsequent grinding process is reduced, which saves time and cost for enterprises. It has less consumables and long life, and can be flexibly applied to various environments.
The laser beam is uniform and of high quality. It can emit light continuously or in pulses, and can realize both heat conduction welding and continuous deep melting welding, and can realize spot welding, butt welding, lap welding, sealing welding, seam welding, etc.
It is also suitable for welding a variety of metal materials, carbon steel, stainless steel, high-strength steel, aluminum, copper and alloy materials, and can process parts and small parts with complex shapes, basically realizing one-time rapid welding and forming.
2. Composition of handheld laser welding machine
The hand laser welder is mainly composed of laser, welding head, control card, wire feeder, cooler, chassis power supply and other parts.
Laser
The device that generates laser is one of the cores of the hand laser welder. Handheld welding equipment is limited by factors such as size and portability. The power of the laser is usually not very large, and the common power is 1000W/1500W/2000W. And because welding is for processing metal materials, lasers are usually fiber lasers that are better for metal.
Welding head (welding gun)
The light and wire feeding parts. It is composed of a handheld handle, a reflector, a welding wire channel and a nozzle. According to the different requirements of the processing technology, the welding head can also be equipped with different nozzles to adapt to different processing environments. The adjusted welding head can deal with hard-to-reach dead corners, corners, and fine seams.
Control card
Also known as handheld welding control system, handheld welding control board, because of its appearance is a card box, it is commonly called a control card by practitioners. The biggest difference between the handheld laser welding control system and traditional welding is that it has an intelligent control system. Through the control system, the operator can adjust various parameters such as laser power, focus, swing direction, etc. After setting, the welding operation can be started. Even inexperienced or inexperienced operators can easily get started.
Wire feeder
As the name suggests, the device for conveying welding wire. The wire feeding speed needs to be adjusted according to the power size and welding speed. Too fast or too slow will affect the quality and appearance of the weld.
Cooler
There are two main ways of handheld laser welding: air cooling and water cooling. Water cooling requires regular inspection and replacement of cooling water to ensure that the water tank is not contaminated. The air-cooled handheld laser welder is a new technology that has emerged in the past two years. The main advantage is that the air cooling system and chassis can be integrated, which is easier to carry and more suitable for outdoor operations.
3. Application fields of handheld laser welding machine
Automobile manufacturing
In the process of automobile manufacturing, laser welding is a very important connection method. Hand laser welders can be used for the manufacture and repair of vehicle bodies, frames and components, improving production efficiency and product quality.
Aerospace
Manufacturing in the aerospace field requires extremely high precision and quality. Handheld laser welding machines can be used for the welding of aircraft fuselages, engine components and aerospace materials, improving production efficiency and product quality.
Medical devices
The manufacture of medical devices requires high-precision and high-quality welding. Handheld laser welding machines can be used in the manufacture of medical devices such as surgical instruments, medical steel plates, artificial joints, etc., improving production efficiency and product quality.
Food packaging
The sealing and aesthetics of food packaging are very important. Hand laser welders can be used for the sealing and connection of food packaging, improving production efficiency and product quality.
Other fields
In addition to the above fields, hand laser welders can also be used in electronics, construction, petrochemicals and other fields.
4. Laser welding or arc welding?
Laser welding and arc welding are two common welding technologies. The choice of laser welding or arc welding depends on the specific application requirements, budget and technical level.
Laser welding
- Laser welding is usually faster than arc welding and is suitable for large-scale production and fast welding needs.
- Laser welding produces welds with high strength, beautiful appearance, small heat-affected zone, and reduced deformation and stress. The initial investment of laser welding equipment is high, and the maintenance cost is relatively high. Operators need to have a certain level of technical skills to ensure the quality of welding.
Arc welding
- Arc welding equipment is relatively cheap and suitable for small businesses and individuals.
- Arc welding technology is mature and relatively simple to operate, suitable for beginners.
- Compared with laser welding, arc welding is slower, which may affect production efficiency.
- Arc welding produces smoke and gas, which may affect the working environment.
