Handheld laser welding machine, also known as laser welding machine, laser welding machine, is the use of handheld welding torch and fiber CW laser integration, the use of polarizer reflection laser generated by the beam to concentrate in the focusing device to produce a huge energy beam, when the high-intensity laser beam irradiated on the surface of the material, part of the light energy will be absorbed by the material and converted into heat energy, so that the material is melted, so as to achieve the purpose of welding.

Whether the handheld laser welding machine is easy to use depends on its core configuration; Second, it depends on its application scenarios. Take the configuration of Leituo handheld laser welding machine as an example:

1) The laser is the standard full power of Chuangxin;

2) The water tank is a Hanli or special water tank;

3) The welding gun is a super multi-functional welding gun;

The core configuration refers to this, and it can be combined with the specific application scenario to see if it is suitable. For details, you can take a look at this article "Handheld Laser Welding Machine Selection Reference Configuration".

3. The welding energy can be accurately controlled, the welding effect is stable, the weld is beautiful and smooth, and the consistency is good;

4. Laser welding is green and safe, and traditional arc welding will produce a lot of dust, welding slag and arc radiation.

Compared with traditional welding machines, handheld laser welding has the following advantages:

1. Cost saving

The cost-saving advantages of handheld laser welding are mainly reflected in improving efficiency and reducing post-welding treatment. The handheld laser welding speed is fast, which is 3 5 times that of traditional argon arc welding, and saves about 80 90 more electricity than argon arc welding. One equipment can reduce the labor cost of more than 3 professional welders.

At the same time, the weld seam is smooth, which can reduce the subsequent grinding process, and the return on investment period is short.

2. High welding quality

The welding quality of handheld laser welding is high, the laser capacity density is high, the welding heat affected area is small, the workpiece has no deformation, no welding scars, and the welding is firm. The weld is smooth and uniform, and it is easy to grind or no grinding after welding. The hand-held sonotrode is equipped with a fiber optic generator, which is flexible and convenient, and has less restrictions on positioning and fixtures, so that laser welding can be operated outdoors.

3. Green and environmental protection

Traditional arc welding will produce a large amount of welding dust, welding slag and arc radiation, which will cause great pollution to the environment. Handheld laser welding can effectively avoid these problems.

4. De-skilling and highly adaptable

Handheld laser welding has a high level of intelligence and easy operation, and can be quickly trained for staff with zero welding experience. At the same time, the handheld laser welding has high adaptability, suitable for metal welding of various specifications, even if the sheet metal internal welding, splicing, and positive angle welding can be easily welded and welded through, and the workpiece can be welded at any part and at any angle.

There are two types of handheld laser welding machines on the market today:

One is water-cooled, equipped with a water tank, the machine is large and heavy, needs maintenance, and has the problem of condensation in summer and freezing in winter.

The other is air-cooled, no water tank, no maintenance, light weight and small size, very portable and flexible.

Chuangxin Laser, an international first-line laser manufacturer, has launched an air-cooled phase change handheld laser welding, weighing 39kg, less than the volume, and the welding gun is currently the lightest, smallest and most portable handheld laser welding in the industry.

What material are you welding, what kind of thickness is it.

Summary. Disadvantages of handheld laser welding machines:

Hello dear, the common welding defects of laser welding machines are as follows:

1.Welding defects - In the process of crack laser welding, due to the small amount of heat input of the laser, the small amount of welding deformation and the stress generated by welding, there will be no high-temperature cracks under normal circumstances. However, due to the different materials and improper selection of process parameters, high-temperature cracks sometimes occur.

2.Welding Defects – Displacement and Changes in WeldabilityWhen laser beam welding is performed with medium to high energy, a plasma controller is used to expel the ionized gas around the molten pool to ensure the reappearance of the weld bead. In addition, in highly reflective and thermally conductive materials such as aluminum, copper and their alloys, the weldability will be changed by laser when welding.

3.Welding defects - welding spatter When laser welding is completed, there will be a lot of metal particles on the surface of some workpieces or materials, and these metal particles are attached to the surface of the workpiece or material, which not only affects the aesthetics, but also affects the use. This phenomenon occurs due to stains on the surface of the workpiece or material, or a galvanized coating.

Handheld laser welding machine introduction:

Hand-held laser welding machine, with a hand-held welding gun instead of the previous fixed optical path, hand-held welding, flexible and convenient, longer welding distance, to overcome the limitation of workbench space, when the size of the workpiece is not uniform, can not be used in the case of automatic welding. Mainly for large workpieces, fixed positions such as inner right angle, outer right angle, plane weld welding, welding heat affected area is small, deformation is small, and the welding depth is large, and the welding is firm. It is a new and flexible welding process for long-distance welding of large workpieces.

It can effectively weld carbon steel, stainless steel, galvanized sheet and other metal materials, and is suitable for tailored welding, overlapping welding, internal and external fillet welding, arc welding, and irregular shape welding.

Handheld laser welding vs. argon arc welding:

Energy consumption comparison: Compared with traditional arc welding, the handheld laser welding machine saves about 80% 90% of electric energy, and the processing cost can be reduced by about 30%.

Comparison of welding effects:

Laser hand-held welding can complete the welding of dissimilar steel and dissimilar metals. High speed, small deformation and small heat-affected zone. The weld is beautiful, smooth, no porosity, and no pollution. Handheld laser welding machines can perform micro open parts and precision welding.

Comparison of follow-up processes:

The heat input is low and the deformation of the workpiece is small, which can obtain an aesthetically pleasing welding surface with no or only minimal treatment (depending on the welding surface effect). Handheld laser welding machines can greatly reduce the labor costs of the huge polishing and leveling operations.

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, a laser passes through an electromagnetic field and the beam does not shift; Lasers can be welded in vacuum, air, and some gaseous environments, 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 heterosexual materials with good results.

4. After laser focusing, the power density is high, and the aspect ratio can reach 5:1 and up to 10:1 when welding high-power devices.

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 assembly welding of micro and small workpieces produced in large quantities.

6. It can weld the parts that are difficult to access, 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, which has made laser welding technology more widely promoted and applied.

7. The laser beam is easy to realize the 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.

The handheld laser welding machine has the characteristics of small size, flexible operation, and easy to learn. The disadvantage is that it needs to be held by hand for a long time, which can cause arm fatigue, and it is not suitable for welding large components. As for whether it is worth buying, it depends on your personal needs, our factory has more small parts to weld, and I bought a Han's Yueming handheld laser welding machine, which is very good to use.
