What are the systems that make up a laser welding machine?

Laser welding is achieved by using a high-energy beam to transform into heat energy to radiate onto the workpiece, then instantly melting and bonding the material. The speed of laser welding is fast that it can satisfy the needs of continuous mass production. Its advantages such as smooth and beautiful processing workpiece, polish-free treatment can save time and costs for manufacturers. Laser welding has gradually replaced the traditional welding. So what are the main components of a laser welder?

1. Laser welding host

Laser welding host machine mainly produces laser beam for welding, which is made up of power supply, laser generator, optical path and control system.

2. Laser welding auto workbench or motion system

This system is used to realize the movement of laser beam according to the welding track under specific requirements. To realize the automatic welding function, there are 3 control forms: workpiece moves with laser head fixed; laser head moves with workpiece fixed; both laser head and workpiece move.

3. Work fixture

During the laser welding process, laser welding work fixture is used to fix the welding workpiece, making it can be repeatedly assembled, positioned and disassembled, which benefits the automatic welding of the laser.

4. Viewing system

Generic laser welder should be equipped with a viewing system, which is conducive to the accurate positioning during the welding programming process and the effect inspection when welding.

5. Cooling system

During the operation of the laser machine, a large amount of heat is generated. So water-cooled way is needed to cool down the laser machine and keep it to the proper temperature range, which helps to ensure the laser beam quality and output power, and prolongs the service life of the laser.

S&A laser welding machine chiller comes with dual temperature control system, while the high temperature circuit cools the laser head and the low temperature circuit cools the laser machine. One device serves several purposes, which saves costs and space. The laser chiller is also equipped with multiple warning protections: time-delay and over-current protection of compressor, flow alarm, ultrahigh/ultralow temperature alarm.

Due to the flexible requirement of laser welding, handheld laser welding machine is popular on the market. Correspondingly, Teyu launches all-in-one handheld laser welding machine chiller, which can be flexibly used matching with your handheld laser welder.

7 industries in which laser welding machine plays a key role

Laser welding has become a part of our daily life and you can often see the trace of laser welding in the items that are commonly seen. In fact, laser welding machine has completely replaced traditional welding techniques in 7 industries. And today, we are going to list them one by one.

Piping industry: water pipe connector, reducing joint, shower fittings and large pipe welding all applied laser welding technique.

Glasses industry: the buckle, the stainless steel/titanium alloy glasses frame require high precision laser welding.

Hardware industry: impeller, water kettle handle, complicated stamping parts and casting parts use laser welding machine.

Automobile industry: motor cylinder head gasket and hydraulic tappet rod seal welding, sparking plug welding and filter welding all require laser welding technique.

Medical industry: medical device and its sealing elements and structural parts welding use laser welding machine to perform welding.

Electronics industry: seal welding of solid-state relay, welding between connector and connector, welding of structural parts of smart phone and MP3 all require laser welding technique.

Home appliance hardware industry: kitchen and bathroom stainless steel door handle, clock, sensor, high precision machinery can often see the trace of laser welding.

Laser welding machine features high focused energy, no pollution and small welding point. It can weld a wide variety of materials with high flexibility and high efficiency. Some laser laser welding machines even integrate with robotic arm, which can achieve a high level of automation.

Laser welding machine uses high power fiber laser or YAG laser source to realize high energy welding. As the heat sources, these two types of laser sources tend to generate lots of extra heat. If those heat continues to accumulate, their lifetime will be greatly affected. And at this time, an industrial water chiller would be ideal. S&A CWFL series and CW series air cooled chillers are suitable to cool fiber laser welding machines and YAG laser welding machines respectively. They feature high precision temperature control and offer various temperature stability to choose from. Some bigger industrial water chiller models even support Modbus-485 communication protocol, making remote control of the chiller become a reality.

Laser application in small home appliance

Home appliances are our daily items that are indispensable. As people’s living standards improve, home appliances have developed from several categories into several hundreds categories. As the competition of big home appliances becomes more and more fierce, many manufacturers shift their product ranges to small home appliances.

Small home appliances have a big market

Small home appliances are often in small size with relative low price and comes in different forms, including electric kettle, soybean milk machine, high speed blender, electric oven, air purifier, etc.. These small home appliances are in huge demand, for they can meet various kinds of requirements from different users.

The common small home appliances are often made from plastics and metal. The plastic part is often the outer shell which is used to prevent electric shock and protect the product. But what really plays the important role is the metal part and electric kettle is one of the typical example.

There are many different kinds of electric kettles in the market and their prices are very different. But what people require is reliability and stability. Therefore, the electric kettle manufacturers gradually employ new technique - laser welding, to weld the kettle body. Generally speaking, an electric kettle consists of 5 parts: kettle body, kettle handle, kettle lid, kettle bottom and kettle spout. To combine all these parts together, the most effective method is using laser welding technique.


Laser welding is very common in electric kettle

In the past, many electric kettle manufacturers would use argon arc welding to weld the electric kettle. But argon arc welding is very slow and the weld line is not smooth and even. That means post-processing is often required. Besides, argon arc welding can often lead to crack, deformation, and internal stress damage. All these posts great challenge to the later post-processing and the reject ratio is likely to increase.

But with laser welding technique, high speed welding can be achieved with high quality tightness and no requirement of polishing. The stainless steel of the kettle body is often very thin and the thinness is often 0.8-1.5mm. Therefore, laser welding machine from 500W to 1500W is sufficient for welding. Besides, it often comes with high speed automatic motor system with CCD function. With this machine, the productivity of the enterprises can be greatly improved.

Welding of small home appliances requires reliable industrial process chiller

The laser welding of small home appliances adopts middle power fiber laser. The laser head will be integrated into the industrial robot or high speed orbital determination sliding device to realize welding. At the same time, since the production capacity of electric kettle is quite big, it requires laser system to work in a long term. That makes adding an industrial process chiller very necessary.

S&A Teyu is an enterprise that is dedicated to the development and production of laser water chiller. After nearly 20 years of development, S&A Teyu has become a reputed water chiller manufacturer in China. The industrial process chillers it produces are applicable to cool CO2 laser, fiber laser, UV laser, ultrafast laser, laser diode, etc.. Nowadays, small home appliance production has gradually introduced UV laser marking system, metal laser cutting and welding system, plastic laser welding system to help improve the productivity. And at the same time, our industrial process chillers are also added to provide efficient cooling for those laser systems.

The advantages of laser welding machine in thin metal production

Laser welding is one of the most important part in laser processing. With high energy laser beam as a heat source, laser welding is a high precision welding technique. It uses high energy laser beam to heat up the surface of the work piece and then the heat will spread from the material surface to the inside. With the parameters of the laser pulse parameters being adjusted, the laser beam energy will melt the materials and then molten bath will form.

Laser welding machine can combine materials of different types, different thickness and different shapes through the laser energy so that the finished work piece can get the best performance from each part.

So what is the advantage of laser welding machine in thin metal production? 

Stainless steel has a wide application in different industries. And thin stainless steel welding has become an important procedure in metal production, but the unique feature of thin stainless steel makes it hard to perform welding on it. So the thin stainless steel welding used to be a great challenge. 

As we know, thin stainless steel has very small heat conductivity coefficient which is only 1/3 of the normal low carbon steel. Therefore, once some of its parts receive heating and cooling during the welding process, it will form uneven stress and strain. The vertical contraction of the weld line will form certain amount of stress on the edge of the thin stainless steel. The drawback of using traditional welding machine on thin stainless steel is more than than this. Burning and deformation are also real headaches for the metal fabricators.

But now, the advent of laser welding machine perfectly solves this challenge. Laser welding machine features small weld line width, small heat affecting zone, little deformation, high welding speed, beautiful weld line, ease of automation, no bubble and no requirement of complicated post-processing. With all these advantages, laser welding machine is gradually replacing traditional welding machine. 

Most of laser welding machines used in the thin metal production are powered by fiber laser from 500W to 2000W. Fiber lasers of this range are easy to generate lots of heat. If those heat can not be dissipated in time, it will cause critical damage to the fiber laser and shorten its lifespan. With industrial water chiller unit, the overheating is not a problem any more. S&A Teyu CWFL series industrial water chiller unit is the perfect cooling solution for the fiber laser ranging from 500W to 20000W. The CWFL series industrial water chiller units share one thing in common - they all have two independent cooling circuits. One is for cooling the fiber laser and the other is for cooling the laser head. This kind of design not only improves the refrigeration efficiency but also saves space for the users, as now only ONE chiller can finish the cooling job of two. Besides, the temperature control range is from 5-35 degree C, which is sufficient enough to provide efficient cooling for the fiber laser welding machines.

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 growing trends of laser welding indicate it will have a quite promising prospect

The popularization of laser technique has greatly improved the industrial production. Laser cutting, laser engraving, laser cleaning, laser welding, laser cleaning and laser cladding have already immersed into various kinds of industries.

Nowadays, laser welding has become the second largest segmented market apart from laser cutting and it accounted for about 15% market share. Last year, the laser welding market was about 11.05 billion RMB and has kept the growing trend since 2016. We can say that it really has a bright future. 


Laser technique was introduced to the domestic market several decades ago. At the initial stage, limited to the insufficient power and low precision of the accessories, it didn’t cause a big attention in the market. However, as the power of the laser technique increases and the advancement of the accessories, the efficiency and precision of laser technique has greatly improved. What’s more, since laser technique goes well with the automation equipment, it has more and more applications. 

The demand of new energy vehicle, semiconductor and lithium battery in the past few years has promoted the development of the laser welding machine. 

One of the growing points for laser welding in the domestic market is its increasing applications in high power or high-end mass processing. Take new energy automobile as an example. During the production of its power battery, laser welding is needed in most of the procedures, including anti-explosion valve seal welding, flexible coupling welding, battery shell seal welding, PACK module welding and so on. We can say that laser welding technique has been involved in the power battery production from the beginning to the end.

Another growing point is handheld laser welding machine. Because of high efficiency, ease of use, no consumables required and environmental friendliness, it is attracting more and more buyers in the laser market.

With the gradually reducing price, it is expected that laser welding market will have a bigger growth. With the demand of laser welding machine, particularly fiber laser welding machine, the demand of its cooling system will also increase. And the cooling system needs to catch up with the growing standard. And S&A Teyu process water chiller CWFL-2000 is powerful to meet that standard. 

CWFL-2000 chiller is widely used to provide efficient cooling for fiber laser welding machine up to 2KW.

Is anti-freezer needed in YAG laser welding machine closed loop chiller?

It is already the middle of November and the temperature in some places of the world has already dropped to 0 degree celsius or lower, which makes some of the YAG laser welding machine closed loop chiller difficult to start. What should be done to deal with this problem?

Well, users can add proportional anti-freezer into the closed loop chiller to prevent the circulating water from freezing. Note: users should turn to the chiller manufacturer for the proportion of the anti-freezer and should also think about the actual application of the chiller. For example, for laser diode water chiller and fiber laser water chiller, it is not suggested to add the anti-freezer, for they use de-ion water as the circulating water.

In respect of production, S&A has invested the production equipment of more than one million RMB, ensuring the quality of a series of processes from the core components (condenser) of industrial chiller to the welding of sheet metal; in respect of logistics, S&A has set up logistics warehouses in the main cities of China, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of after-sales service, all the S&A water chillers are underwritten by insurance company and the warranty period is two years.
