Laser welding machine vs plasma welding machine

Laser welding machine is pretty common in material processing. The major working principle of laser welding machine is to use high energy laser pulse to perform local heating in the tiny area of the materials and then the laser energy will proliferate inside the material by heat transfer and then the material will melt and become certain molten pool.


Laser welding is a novel welding method and is widely used to weld thin-walled materials and high precision parts. It can realize spot welding, jam welding, stitch welding and seal welding. It features heat affecting zone, little deformation, high welding speed, neat weld line and no post-processing required. What’s more, it is quite easy to be integrated into automation line. 

Laser welding machines are having wider and wider applications and gradually appear in various industries. At the same time, with the market demand changes, laser welding machine seems to gradually replace plasma welding machine. So, what is the difference between laser welding machine and plasma welding machine? 

But first, let’s take a look at their similarity. Laser welding machine and plasma welding are both beam arc welding. They have high heating temperature and are able to weld materials with high melting point.

However, they are also different in many ways. For plasma welding machine, the low temperature plasma arc belongs to shrunk arc and its highest power is about 106w/cm2. As for laser welding machine, the laser belongs to photon stream with good monochromaticity and coherency and its high power is about 106-129w/cm2. The highest heating temperature of laser welding machine is far bigger than that of plasma welding machine. Laser welding machine is complicated in structure and is costly while plasma welding machine has simple structure and low cost, but laser welding machine can be more easily integrated into CNC machinery or robot system.

As mentioned before, laser welding machine has complicated structure and that means it has quite many components. And one of the components is cooling system. S&A Teyu develops air cooled process chillers suitable for cooling different kinds of laser welding machines, such as YAG laser welding machine, fiber laser welding machine, handheld laser welding machine, etc.. The air cooled process chillers are available in stand-alone type and rack mount type, which can suit different needs of the users.

The wide applications of laser cutters suggest more opportunities for the manufacturing industry

Nowadays, laser cutters are having wider and wider applications and gradually replacing plasma cutter, waterjet cutting machine, flame cutting machine and CNC punch press because of high processing efficiency & precision, superior cutting surface quality and the ability to perform 3D cutting.


According to different laser generators, the current laser cutters in the market can be basically categorized into CO2 laser cutterYAG laser cutter and fiber laser cutter

Comparing with CO2 laser and YAG laser, fiber laser is more advantageous because of its high quality light beam, stable output power and easy maintenance. 

As more and more metal is used in life and industrial application, the application of fiber laser cutter is becoming wider and wider. No matter whether it is metal processing, aerospace, electronics, home appliance, automobile, precision parts or gift items or kitchenware in our daily life, laser cutting technique is often applied. No matter it is stainless steel, carbon steel, aluminum, iron or other kinds of metals, laser cutter can always finish the cutting job very efficiently. 

Fiber laser is relatively high-performance cutting laser for the time being and its life could be tens of thousands of hours. Running failure caused by itself is pretty rare unless it is human factor. Even working for a long time, fiber laser won’t produce vibration or other bad effects. Comparing with CO2 laser whose reflector or resonator needs regular maintenance, fiber laser don’t any of those, so it can save a huge maintenance cost. 

Fiber laser cutting machine can adapt to the changing needs of productivity. The work piece doesn’t need any further polishing, burr removing and other post-processing procedures. This has further saved labor cost and processing cost, which improved the production efficiency to a great extent. Besides, the overall energy consumption of fiber laser cutter is 3 to 5 times less than that of CO2 laser cutter, which increases the energy efficiency by 80%. 

Well, to maintain the best running performance of the fiber laser cutter, the fiber laser must be well taken care of. To do that, the best way is to add an air cooled chiller system. S&A Teyu CWFL series air cooled chiller system is able to take away the heat from the fiber laser cutter by providing efficient cooling for the fiber laser and the laser head respectively, thanks to its dual temperature design. This CWFL series air cooled chiller system comes with high performance water pump so that stable water flow can be ongoing continuously. Some higher models even support Modbus485 communication protocol to realize communication between the laser system and the chiller.

When laser meets robot, they become perfect pair in industrial automation

The advent of robotic technique has brought new opportunity to the laser industry. Right now, domestic robotic laser has achieved primary development and its market size continues to grow. It is expected that the industry is going to be very promising.


Laser processing as a non-contact machinery processing has become an indispensable part in industrial manufacturing sector because of high quality, high output, high flexibility and high adaptability. It has been well recognized in the industrial manufacturing sector in the past 10 years. And the great success of laser processing lies in the assistance of robotic technique.

As we all know, robot is quite outstanding in industrial manufacturing sector, for it can not only work 24/7 but also reduce mistakes and error and is able to work normally under extreme conditions. Therefore, people incorporate robotic and laser technique into one machine and that is robotic laser or laser robot. This has brought new energy to the industry. 

From the development timeline, laser technique and robot technique were quite similar in the development pace. But these two don’t have “intersection” until the late 1990s. In 1999, German robotic company first invented the robot arm with laser processing system, which indicates the time when laser met robot for the first time. 

Comparing with traditional laser processing, robotic laser can be more flexible, for it breaks the limitation of the dimension. Although traditional laser has wide applications. Low powered laser can be used to perform marking, engraving, drilling and micro-cutting. High powered laser is applicable to perform cutting, welding and repair. But all these can only be 2-dimension processing, which is quite limited. And robotic technique turns out to make up the limitation. 

Therefore, in the past few years, robotic laser is become quite heated in laser cutting and laser welding. Without the limitation of cutting direction, robotic laser cutting can also be called as 3D laser cutting. As for 3D laser welding, although it hasn’t been widely applied, its potential and applications are gradually known by people. 

Right now, domestic laser robotic technique is going through the speed-up period. It is gradually applied in metal processing, cabinet production, elevator manufacturing, shipbuilding and other industrial areas. 

Most of the laser robots are supported by fiber laser. And as we know, fiber laser will generate heat when it is working. To keep the laser robot at its optimum, efficient cooling needs to be provided. S&A Teyu CWFL series water circulating chillerwould be an ideal choice. It features dual circulation design, which indicates independent cooling can be provided for fiber laser and the welding head at the same time. This can not only save cost but also space for the users. In addition, CWFL series water circulating chiller is able to cool up to 20KW fiber laser.

Overview and forecast of domestic industrial laser market

It is estimate that the global laser cutting machine market will grow by 7%-8% each year in the coming years. By 2024, it is expected to reach 2.35 billion US dollars. The demand of fiber laser cutter from European and North American countries continues to grow, which helps promote the technological advancement in fiber laser cutter. Meanwhile, the increasing demand from automobile industry, more and more competitive environment and the increasing applications of fiber laser cutter, these all stimulate the development of the Chinese market. In the past few years, Chinese fiber laser cutting machine has been leading in the global market and its market share continues to grow year by year.


From the current trend, it is estimated that in the coming 10 years, fiber laser will still be the main industrial light source, since it is very stable in performance and application. Comparing with 2019, the production value of laser cutting market increased by 15% in 2020 and domestic fiber laser source dominates in the production value. For domestic 12KW fiber laser cutters, 1500 units have been installed. 40KW domestic fiber laser cutters have already been successfully developed and sold. In the coming future, with the demand of engineering machinery increasing, the demand of fiber laser cutting machine will continue to grow. 

For the time being, laser groove cutting is also a heated point. Many manufacturers begin to invest in the R&D of the laser groove cutting machine and have great success. Adding laser groove cutting function in high power laser machine can integrate cutting, welding, milling and other procedures in one machine, which dramatically improves the processing efficiency, product quality, workpiece precision and saves cost and resources and flexibly cut the special pipes. 

Indeed, high power laser plays a leading role in processing area and laser cutting accounts for big market share. As fiber laser develops, laser cutting machine has become standard product. Since 2019, the cost performance of 10KW+ fiber laser cutting machine has begun to surpass plasma cutting, flame cutting in thick plate and other metal processing sectors. In the past two years, fiber laser cutting machine has been heading towards higher power, higher cutting thickness & speed, more safeness, which gradually replaces traditional cutting solutions. 

There is no doubt that fiber laser cutting industry is experiencing a new round of update and transformation. In order to let this industry have more development, fiber laser cutter manufacturers need to expand the applications of the machine so that it can be adapted to different materials and different technique. It is believed that fiber laser cutter will have deeper applications in new construction, shipbuilding, aerospace, automobile, engineering machinery, medical equipment, bathroom hardware, lighting, sheet metal processing and other industries. 

With fiber laser cutter becomes more and more upgraded, its accessory also needs to catch up with it. As an important accessory of fiber laser cutter, laser cooler has become more and more precise. S&A Teyu develops CWFL series laser coolers whose temperature stability ranges from ±0.3℃ to ±1℃. These laser coolers are applicable to cool 0.5KW to 20KW fiber laser cutters.

Fiber laser cutter vs CO2 laser cutter

 As we all know, fiber laser cutter is ideal for processing metal materials while CO2 laser cutter is suitable for cutting non-metal materials. But other than that, how much do you know about their differences? Today, we are going to go deep about it.


First, laser generator and the laser beam transfer is different. In CO2 laser cutter, CO2 as a kind of gas is the medium that generates laser beam. For fiber laser cutter, the laser beam is generated by multiple diode laser pumps and then transferred by flexible fiber-optic cable to the laser cut head instead of being transferred by reflector. This kind of laser beam transfer has many advantages. For example, the laser cutting table size can be more flexible. In CO2 laser cutter, its reflector needs to be installed within certain distance. But for fiber laser cutter, it doesn’t have this kind of limitation. Meanwhile, comparing with CO2 laser cutter of the same power, fiber laser cutter can be more compact because of the fiber’s ability of being curved. 

Second, the electro-optical conversion efficiency is different. With complete solid-state digital module, simplified design, fiber laser cutter has higher electro-optical conversion efficiency than CO2 laser cutter. For CO2 laser cutter, the actual efficiency rate is around 8%-10%. As for fiber laser cutter, the actual efficiency rate is around 25%-30%. 

Third, the wavelength is different. Fiber laser cutter has short wavelength, so materials can better absorb the laser beam, especially metal materials. That’s why fiber laser cutter can cut brass and copper and non-conductive materials. With smaller focal point and deeper focal depth, fiber laser is capable of cutting thin materials and medium-thickness materials very efficiently. When cutting 6mm thickness material, 1.5KW fiber laser cutter can have the same cutting speed of 3KW CO2 laser cutter. For CO2 laser cutter, the wavelength is around 10.6μm. This kind of wavelength makes it very ideal for cutting non-metal materials, for these materials can better absorb CO2 laser light beam. 

Fourth, maintenance frequency is different. CO2 laser cutter needs regular maintenance, including reflector, resonator and other components. And since CO2 laser cutter needs CO2 as the laser generator, the resonator can easily be polluted because of the purity of the CO2. Therefore, cleaning in the resonator is also needed periodically. As for fiber laser cutter, it hardly needs any maintenance. 

Although fiber laser cutter and CO2 laser cutter have so many difference, they share one thing in common. And they both need laser cooling, for they inevitably generate heat in the operation. By laser cooling, we often mean adding an efficient laser water chiller

S&A Teyu is a reliable laser chiller manufacturer in China and has been an expert in laser cooling for 19 years. The CWFL series and CW series laser water chillers are specifically designed for cooling fiber laser and CO2 laser respectively. It is quite easy to size a water chiller for your laser cutter, for the main selection guide depends on the laser power. If you are not sure which laser water chiller is suitable for your laser cutter, you can just e-mail to marketing@teyu.com.cn and our sales colleague will help you decide.

The application and development of UV laser and ultrafast laser

Laser source is the key part of all the laser systems. It has many different categories. For example, far infrared laser, visible laser, X-ray laser, UV laser, ultrafast laser, etc.. And today, we mainly focus on ultrafast laser and UV laser.


The development of ultrafast laser

As laser technology continues to develop, ultrafast laser was invented. It features unique ultra-short pulse and can achieve very high peak light intensity with relative low pulse power. Different from traditional pulse laser and continuous wave laser, ultrafast laser has ultra-short laser pulse, leading to relatively big spectrum width. It can solve the problems that traditional methods are hard to solve and has the amazing processing ability, quality and efficiency. It is gradually attracting the eyes of the laser system manufacturers. 

Ultrafast laser is mainly used for precision processing

Ultrafast laser can achieve clean cutting and won’t damage the surroundings of the cut area to form rough edges. Therefore, it is very advantageous in processing glass, sapphire, heat-sensitive materials, polymer and so on. Besides, it also plays an important role in the surgeries that require ultra-high precision.

The continuous update of laser technology has already made ultrafast laser “stepped out” from the laboratory and entered into industrial and medical sectors. The success of ultrafast laser relies on its ability to focus the light energy within picosecond or femtosecond level in very tiny area. 

In industrial sector, ultrafast laser is also suitable for processing metal, semiconductor, glass, crystal, ceramics and so on. For brittle materials like glass and ceramics, their processing requires very high precision and accuracy. And ultrafast laser can perfectly do that. In medical sector, many hospitals can now perform cornea surgery, heart surgery and other demanding surgeries. 

UV laser is very ideal for scientific research, industry and OEM system integrated development

The major application of UV laser include scientific research and industrial manufacturing equipment. Meanwhile, it is widely used for chemical technology and medical equipment and sterilizing equipment that requires ultraviolet light radiation. DPSS UV laser based on Nd:YAG/Nd:YVO4 crystal is the best choice for micromachining, so it has a wide application in processing PCB and consumer electronics. 


UV laser features ultra-short wavelength & pulse width and low M2, so it can create a more focused laser light spot and keep the smallest heat affecting zone in order to achieve more precise micro-machining in relatively small space. Absorbing the high energy from the UV laser, material can vaporize very quickly. So the carbonization can reduce. 

The output wavelength of UV laser is below 0.4μm, which makes UV laser the ideal choice for processing polymer. Different from infrared light processing, UV laser micro-machining is not heat treatment. Besides, most of the materials can absorb UV light more easily than infrared light. So is polymer. 

The development of domestic UV laser

In addition to the fact that foreign brands like Trumpf, Coherent and Inno dominate the high-end market, domestic UV laser manufacturers are also experiencing encouraging growth. Domestic brands like Huaray, RFH and Inngu are getting higher and higher sales per year. 

No matter whether it is ultrafast laser or UV laser, they both share one thing in common - high precision. It is this high precision that makes these two kinds of lasers becoming so popular in the demanding industry. However, they are very sensitive to thermal changes. A small temperature fluctuation would cause a huge difference in the processing performance. A precise laser cooler would be a wise decision. 

S&A Teyu CWUL series and CWUP laser coolers are specifically designed for cooling UV laser and ultrafast laser respectively. Their temperature stability can be up to ±0.2℃ and ±0.1℃. This kind of high stability can keep the UV laser and the ultrafast laser at a very stable temperature range. You no longer have to worry that the thermal change would affect the performance of the laser.

Why you need a water recirculating chiller for your CO2 laser cutter

In textile industry and advertising industry, CO2 laser cutter is the most commonly seen processing machine. In addition to textile and acrylic which is the major material of advertising board, CO2 laser cutter can also work on other kinds of non-metal materials, such as wood, plastics, leather, glass and so on, for non-metal materials can absorb the laser light from CO2 laser tube better.

However, like many other kinds of laser sources, CO2 laser tube generates heat. As the running time continues, more and more heat will accumulate in the CO2 laser tube. This is very dangerous, for CO2 laser tube is mainly made of glass and glass can easily crack under high temperature. In this situation, you have to consider replacing a new one. But wait, do you know that a new CO2 laser tube is costly? As the core component of CO2 laser cutter, the CO2 laser tube can cost you several thousands US dollars. And the bigger the power, the higher price of the CO2 laser tube will be. So you might ask, “ Is there other more cost-effective way to keep the laser tube cool so that I don’t have to worry about replacing with a new one?” Well, many people would think of air cooling, but in fact, air cooling is more sufficient to remove the heat for very small-powered CO2 laser tube. For bigger-powered CO2 laser tube, water recirculating chiller is the most efficient cooling method, for it can provide water circulation at consistent temperature, water flow and water pressure. More importantly, a water recirculating chiller can regulate the temperature which air cooling is incapable of. 

S&A Teyu laser water chillers offer cooling capacity ranging from 800W to 30000W, applicable to cool CO2 laser tubes of different powers. By providing precise temperature control, our chillers can help prolong the life of the CO2 laser tube so that the cutting quality of the laser cutter can be guaranteed. If you are not sure which chiller model is suitable for you, you can just e-mail to marketing@teyu.com.cn or leave your message at https://www.teyuchiller.com and our colleagues will help you choose the right chiller model.
