Abstract: Laser is another major invention of mankind since the 20th century after nuclear energy, computers, and semiconductors. It is called the fastest knife, the most accurate ruler, and the brightest light. The English name Light Amplification by Stimulated Emission of Radiation means to expand by stimulated radiation. As early as 1916, Einstein put forward the important theoretical basis of laser technology-the concept of stimulated emission. Since the first laser was obtained by mankind in 1960, laser technology has developed rapidly. With more than 60 years of accumulation, laser technology has played an irreplaceable role in many fields.


Laser is another major invention of mankind since the 20th century after nuclear energy, computers, and semiconductors. It is called "the fastest knife", "the most accurate ruler", and "the brightest light". The English name Light Amplification by Stimulated Emission of Radiation means "light amplification by stimulated emission."

As early as 1916, Einstein put forward the important theoretical basis of laser technology-the concept of stimulated emission. Since mankind obtained the first laser in 1960, laser technology has developed rapidly. With more than 60 years of accumulation, laser technology has played an irreplaceable role in many fields. According to statistics, laser technology supports more than 13% of the global GDP (SPIE data). In the industrial field, the world is entering the "light stage".

From the perspective of technological advantages, laser technology relies on its own characteristics and advantages to promote the further development of the industry:

  1. Non-contact processing, no direct impact on the workpiece, no mechanical deformation;

  2. There is no "tool" wear and no "cutting force" acting on the workpiece during laser processing;

  3. In the laser processing process, the laser beam has high energy density, fast processing speed, small heat-affected zone, small thermal deformation of the workpiece, and small subsequent processing volume;

  4. Because the laser beam is easy to guide, focus, and realize the direction change, it is very easy to cooperate with the numerical control system, which is an extremely flexible and flexible processing method;

  5. High production efficiency, stable and reliable processing quality, green and environmentally friendly processing, good economic and social benefits.


International laser companies lead the development of the industry

Judging from the revenue figures of global laser-related companies, European and American laser manufacturers such as Trumpf, IPG, Coherent, and II Lu are the main suppliers in the mid-to-high-end market, occupying a major market share and having excellent core product technologies.

1. TRUMPF (China) Co., Ltd.

High-power green laser TruDisk 2021

The high-power green laser TruDisk 2021 can provide a maximum output power of 2kW with a beam parameter of 6mm·mrad, which is very suitable for pure copper welding. Because of its good beam quality, it can be used for high-quality deep penetration welding, and also for heat conduction welding to achieve a uniform and continuous weld surface.

TRUMPF's unique green laser is very suitable for copper welding tasks, especially for deep penetration welding and thermal conduction welding. It can obtain high-quality welding results, with a power of up to 3kW and very stable, and it has a good effect of suppressing spatter during welding. It can also weld other commonly used materials, such as stainless steel or aluminum, to realize the flexible deployment of a laser in multiple applications. For copper processing, other laser technologies cannot yet provide a dual-purpose welding method.

The newly upgraded ProCutter 2.0 series brings more outstanding performance and automated performance. The newly designed cutting head gas path can achieve high-quality and faster cutting.

More importantly, it can also provide a wider parameter window, making it easier to obtain the best cutting parameters. On the other hand, ProCutter 2.0 is ready for Industry 4.0. It can be docked with automatic nozzle replacement equipment, making production more automated and efficient. The built-in updated sensor can detect the contamination and condensation of the lens in the cutting head and send out an alarm signal. All the detection data can be read in the mobile terminal through the wireless network, which is convenient for users to monitor the running status of the cutting head.

Product advantages:

Autofocus makes the cutting system more automated

Lightweight design and fast acceleration

Drift-free distance sensor

Continuous protection lens monitoring

Closed light path protection

PierceTec automatic perforation

CoolTec cooling technology quickly cools the surface temperature of sheet metal

LED operation indicator shows cutting head status

Through the wireless network, the monitoring data can be read on the mobile terminal or CNC system

There are pressure sensors in the cutting head and at the nozzle
