4 in 1 Handheld Metal Laser Welding Machine

Laser beam is used for welding. The diameter of the laser beam is very small and high-precision welding can be achieved. Compared with traditional welding methods, the welding seams of handheld laser welding machines are smaller and the welding effect is more beautiful. It is not limited by the size and shape of the workpiece and can be moved at will for welding, with a wider scope of application.

Features of 4 in 1 handheld metal laser welding machine

1. Closed design, designed by ourselves based on the principles of laser science, has a more reasonable structure, is dustproof, and has good heat dissipation, effectively extending the service life of machine parts.

2. Can be used to clean the workpiece surface. By adjusting the parameters of the laser beam, dirt, oxide layers, etc. on the surface of the workpiece can be removed and its original smoothness and brightness can be restored.

3. It is equipped with an original optical fiber cable with a length of 10 meters, thereby overcoming the limitations of the workbench space and enabling outdoor welding cleaning and long-distance welding cleaning.

4. The machine has multiple safety alarm functions. The trigger switch is only effective when the welding copper nozzle touches the metal and the safety clip clamps the metal plate. The welding copper nozzle will automatically lock after it is removed from the workpiece. The machine's high safety ensures the absolute safety of the operator during work.

5. Our machine has dual protection functions for water and air paths (patented technology), which effectively avoids damage to the laser lens or optical components caused by operator misoperation, thereby greatly reducing the machine's failure rate and effectively Extends the life of consumables.

Advantages of 4 in 1 handheld metal laser welding machine

1. High precision and quality

Handheld laser welding equipment features high precision and high quality. Due to the high focus of the laser beam, the energy density during the welding process is high, and the welding result has a small heat-affected zone and better welding quality. At the same time, the welding accuracy of handheld laser welding equipment can reach about 0.2mm.

2. Fast welding speed

The welding speed of handheld laser welding equipment is very fast compared to traditional welding methods, mainly due to the high power of the laser beam. During the welding process, the laser beam can quickly scan the weld seam and also complete the welding task quickly. This undoubtedly improves production efficiency and reduces production costs.

3. No material restrictions

It can weld almost all metal materials, including stainless steel, carbon steel, aluminum alloy, etc. Therefore it can meet a wide range of application needs.

4. Not limited by space

The laser welding machine and welding gun are integrated together, and the handheld laser welding equipment can be easily moved to perform a variety of welding tasks, whether indoors or outdoors, whether flat or curved.

5. Easy to operate

The operation is simple, easy to learn and quick to get started, and there is no technical requirement for operators. Ordinary workers can start the operation after a short training, and can easily achieve high-quality welding effects. There is no need for secondary polishing after laser welding, thus saving a lot of time. Labor costs.

Remark: Double weld thickness can be achieved if the material is welded from both sides in two times.

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.
