Laser welding is a non-handling method that allows metal parts to be assembled more evenly through the laser beam. This type of welding is suitable for applications that require high speed and thin welding with low thermal distortion.
The speed of this process, as well as the ability to control the quality of welding during operation and elevated automation, make laser welding a widely used method in many sectors of the industry such as the medical, electronics, tool manufacturing and automotive sector.
Why choose laser welding machine?
Laser welding equipment has several advantages:
Very fast:
The laser allows the metal to expand at a much faster rate, while reducing the risk of deformation. This technology is particularly effective in importing large quantities of sheets and is therefore widely used in the automotive industry.
It is also very accurate:
- They allow for local, very good, very clean, almost invisible welding.
- They are best suited for welding small parts.
- This type of welding is very popular in the dental and jewelry industries as it provides the best possible fit.
- It is also possible to split the pole relaser into several poles to provide welding which is even more orderly.
They can be adapted to different different parts shapes and properties:
Laser welding machines are mainly used for injecting metals, including refractory metals. It is also possible to insert non-metallic components with them, such as porcelain and glass. You can use them to create parts with very different shapes.
They do not wear out:
The laser welding equipment for sale can work without touch, so there is no risk of wear and tear on the machine. There is also no need to change equipment or electrodes, which becomes a clear opportunity in terms of waste minimization.
They can be ordered digitally:
- It is now possible to control the quality of welding from the pump during welding manufacturing.
- The high level of automation allowed by such systems also makes it possible to detect and solve any type problems.
- Therefore, it should be noted that laser welding equipment also has some disadvantages:
The price of laser equipment is still high.
This technology requires high precision during adjustment to prevent laser beam deflections in parts. The laser weld is thinner than that obtained by electron beams, making the structure unsuitable for inserting high-gloss metal.

Pulsed or continuous laser?
Laser welding machine may be equipped with one of the following two types of laser: pulsed laser or continuous laser. The choice of one over the other depends on the thickness of the item you want to combine.
The pulsed laser:
- Suitable for lightweight and thin steel.
- It protects them from deformity or melting.
- This type of pulsed laser is widely used weld sheet metal, razor blades, gold jewelry chain links and titanium pacemakers.
The continuous laser:
- Recommended welding thick sections.
- It is particularly effective on refractory metals.
- It can cause problems if used on metal or a very thin layer. In these cases the laser may damage, damage or dissolve the component.
How to choose a laser beam source?
There are three types of materials: fiber laser, CO2 laser and Nd: YAG laser. The choice of sauce depends on the type of laser you selected (roasted or continued).
The fiber laser:
- This technology is based on sharp beams and beams that allow for continuous and sharp work to be done.
- Like the CO2 laser, the fiber laser can penetrate deep sheets with high speed and efficiency.
- It is easy to integrate into the machine on other lasers both in terms of operation and configuration.
- This laser provides an average performance of 25%.
The CO2 laser:
- This technology uses a gas mixture of carbon dioxide, helium and nitrogen which is energy-efficient and modified to maintain efficiency.
- Like a fiber laser, the CO2 laser can penetrate deep sheets with high speed and efficiency.
- It is more effective at penetrating harder metals than the fiber laser so it is more widely used.
- It is flexible and can penetrate thicker and lighter materials than the fiber laser.
- This laser gives an average performance of 7% of 8,000 W.
The Nd: YAG laser:
- Allows effective control of power, time and shape of laser pulses.
- It is adjusted to pulsed mode.
- But it emits gases of various waves that do not reach their purpose and then disappear in the form of heat.
- This type of laser has less energy (3 to 4% efficiency) than CO2 lasers (7 to 10%) and fiber lasers (25 to 30%).
What parameters should be checked?
Before using your laser welding machine, you will need to check a number of parameters. Here are some common steps you can take to ensure that your digestive system is successful.
Adjust the power
- It is important to adjust the power properly in order to adjust the power to the path. This prevents wastage of energy.
- Make sure you have a real wooden diameter
- The diameter affects welding performance.
- We recommend that you choose a wooden relaser with a diameter between 0.2 and 2 mm.
Check the pulse frequency
High pulse frequencies cause pulse power which is too low causing welding to malfunction or malfunction.
Check the waveform of laser pulses
- We recommend that you change the waveform according to the metal you want to insert.
- If you use an incomplete waveform, 60% to 98% of the laser power is lost and your welding operation is faulty.
What is the solution for my welding machine?
There are 3 types of designs available for welding machines:
- Manual configuration
- Semi-automatic adjustment
- Automatic configuration
