The lasers quickly heat the metal while limiting the risk of deformation. This process is widely used in the automotive industry due to its particular advantages for welding large quantities of sheet metal. It is also very true. They allow local, excellent, clean and almost invisible welds. Particularly suitable for welding small sizes. This type of welding is very popular in the dental and jewelry industry because it provides the most aesthetically pleasing weld. It can also split the laser beam into multiple beams to provide more welds.
It can be used for a variety of graphics and materials. Laser welding machines are mainly used for welding metals, including refractory metals, you can visit this link to get best laser welders . It can also bond non-metallic materials such as ceramics and glass. You can use them to solder many different sizes. They do not wear out: The laser welding machine works without contact, so there is no risk of using the machine.
In addition, there is no need to replace tools or electrodes, which is a great advantage in reducing waste.
You can post orders digitally. Now you can control the welding quality from your computer during the welding process.
The level of automation that these processes allow can be studied and solved effectively.
However, laser welding technology also has some disadvantages:
The cost of installing laser equipment is also very high. This technology requires high alignment during operation to avoid interference of the laser beam on the part.
Laser welding is not suitable for welding highly reflective metals as it is thinner than can be achieved with an electron beam.
The advantages of the laser welding machine:
Laser welding machines can be equipped with one of two types of lasers: pulsed lasers or continuous lasers. The choice of one or the other depends on the thickness of the material you wish to weld. Pulsed laser:
Suitable for light and thin metals.
Prevents warping or melting. This type of pulse laser is mainly used to weld plates, razors, gold jewelry chain links and titanium heart pacemakers. It is especially good for refractory metals. This can be a problem if you use metal or materials that are too thin. In this case, the laser can damage, deform or melt a part.
Although more expensive than pulsed lasers, it also reduces operating costs. The machine uses a mixture of carbon dioxide, helium and nitrogen electrically charged and optimized for continuous operation.
Like fiber lasers, CO2 lasers can penetrate thick sheets at high speed and high efficiency. But they do not all reach their target and then emit pulses of different wavelengths which dissipate in the form of heat.
This type of laser is much less energy efficient (3-4% efficiency) than CO2 lasers (7-10%) and fiber lasers (25-30%).
What indicators should I check? Before using a laser welding machine, you need to check some of the faults. Here are some general tips to help you get your welding job done. It’s a good idea to change the waveform depending on the metal you want to weld. Improper use of the waveform will result in a loss of 60-98% of the laser energy and cause the welding operation to fail. Which configuration should I choose for my welding machine? There are three types of configurations available for welders. It is more compact than semi-automatic and automatic machines. They are equipped with manual or automatic doors. The operator is responsible for scheduling the parts to be welded. This machine is suitable for best productions.
