As the core device of this technology, laser welding machines play a vital role in production lines in various fields, from automobile manufacturing to electronic equipment manufacturing to the aerospace field. However, the stability and safety of the laser welding process depend on multiple factors, one of the most important of which are the power supply and related electrical safety measures.
To minimize potential electrical risks, this article will discuss the power requirements and electrical safety precautions of laser welding machines, including understanding how laser welding machines work, the power and voltage requirements of laser welding machines, and what electrical safety precautions are required for laser welding machines Risks and how to avoid them, etc.

Working principle of laser welding machine

The laser welding machine is a high-precision welding equipment that uses laser beams to heat, melt, and connect workpieces. Its working principle is based on the high-energy characteristics of the laser and the absorption and conduction of the laser by materials.

Laser generation: The laser welding machine contains a laser generator inside, usually a gas laser generator or a solid laser generator. In a laser generator, energy is converted into laser beams, which are highly focused and capable of delivering high energy density in a very short time.
Beam focusing: The laser beam is focused through a lens or mirror so that it can be accurately focused on the welding area. The focused laser beam has extremely high energy density and can quickly heat the workpiece surface.
Material heating and melting: When the laser beam irradiates the surface of the workpiece, the irradiated material absorbs the laser energy and heats up rapidly. As the temperature increases, the material begins to melt and form a molten pool. The high energy density of the laser beam allows the temperature of the molten pool to reach a temperature high enough to melt the material, while also creating a molten pool in a short time.
Joining and solidification: When the surfaces of two workpieces are heated to a high enough temperature, their molten pools fuse and form a join. Under the control of the laser welding machine, the moving speed and focus position of the laser beam are precisely adjusted to ensure the formation of the molten pool and the quality of the connection. Once welding is complete, the molten pool cools and solidifies, forming a strong welded joint.

Therefore, the welding method has the characteristics of high efficiency, high precision, and adaptability to various materials, and has been widely used in the modern manufacturing industry.

Power supply and voltage requirements of laser welding machine

As a high-precision and high-efficiency welding equipment, laser welding machine has strict requirements for a stable and reliable power supply. While ensuring the normal operation of the laser welding machine, appropriate voltage and power configuration are also key factors to ensure welding quality and operational safety. The following are the main contents of the power supply and voltage requirements of the laser welding machine:

Stable power supply

Laser welding machines have high requirements for the stability of the power supply. A stable power supply can ensure that the laser welding machine can provide sufficient power during operation and maintain the stability of the laser beam. The instability of the power supply will cause power fluctuations during the welding process, thus affecting the welding quality and efficiency.

Suitable voltage frequency

Generally speaking, laser welding machines are suitable for 50Hz or 60Hz AC power supply. A mismatch in voltage and frequency may cause the laser welding machine to fail to start normally or work unstable, so it is necessary to ensure that the power supply provided has a suitable frequency.

Suitable voltage level

Different models of laser welding machines may have different voltage level requirements. Normally, the voltage requirements of laser welding machines are between 200V and 400V. Ensuring that the power supply voltage provided to the laser welding machine meets the equipment specifications is an important step to ensure its normal operation.

Protection against voltage fluctuations

To sum up, choosing a laser cutting machine suitable for specific applications is of great significance to an enterprise’s production efficiency, product quality, cost control, and market competitiveness. Therefore, when choosing a laser cutting machine, companies should fully consider their own production needs and product characteristics, and choose the most suitable model and specifications.

Power cord and socket standards

To provide a stable power supply, you must ensure that the power lines and sockets comply with the safety standards of the corresponding country or region. Correct power line and socket standards can effectively reduce power failures and safety risks and ensure the normal operation of the laser welding machine.

The power and voltage requirements of laser welding machines are important factors in ensuring the normal operation of the equipment and welding quality. Only in this way can the advantages of laser welding technology be fully utilized, production efficiency improved, welding quality ensured, and the safety of operators and equipment guaranteed.
