The brief analysis of the development of handheld laser welding system

As is known to all, laser features good monochromaticity, good brightness and high degree of coherence. And as one of the most popular laser applications, laser welding also uses light produced by laser source and then focused by optical treatment. This kind of light has a great amount of energy. When it projects on the welding parts that need to be welded, the welded parts will melt and become a permanent connection.

About 10 other years ago, the laser source used in laser welding machine in the domestic market was solid state light pumping laser which has huge energy consumption and large size. In order to solve the drawback of “difficult to change the light path”, fiber optic transmission based laser welding machine was introduced. And then inspired by foreign handheld fiber optic transmission device, the domestic manufacturers developed their own handheld laser welding system.

This was the 1.0 version of the handheld laser welding machine. Since it uses fiber optic flexible transmission, the welding operation became more flexible and more convenient.

So people may ask, “Which one is better? The TIG welding machine or the 1.0 version of handheld laser welding machine?” Well, these are two different types of device with different working principles. We can only say that they have their own applications.

TIG welding machine:
1.Applicable for welding materials of more than 1mm thick;
2.Low price with small size;
3.High weld strength and suitable for a wide variety of materials;
4.The welding spot is big but with beautiful appearance;

However, it also has its own drawbacks:
1.The heat affecting zone is quite big and deformation is likely to occur;
2.For materials with 1mm below thickness, it is easy to have bad welding performance;
3.The arc light and the waste smoke are bad for human body

Therefore, TIG welding is more suitable for welding medium thickness materials that require certain degree of strength welding.

1.0 version of handheld laser welding machine

1.The focal spot was quite small and precise, available to be adjusted between 0.6 and 2mm;
2.The heat-affecting zone was quite small and unable to cause deformation;
3.No requirement of post processing like polishing or something like that;
4.No waste smoke generates

However, since the 1.0 version of handheld laser welding system was after all a new invention, its price was relatively high with high energy consumption and large size. What’s more, the weld penetration was pretty shallow and the welding strength was not so high.

Therefore, the 1.0 version of handheld laser welding machine happened to conquer the drawbacks of TIG welding machine. It is suitable for welding thin plate materials which requires lower welding strength. The weld appearance is beautiful and requires no post-polishing. This makes handheld laser welding machine began to be used in advertising and grinding tool repair business. However, the high price and high energy and big size prevented it to be widely promoted and applied.

But later in 2017, domestic laser manufacturers were booming and domestic high performance fiber laser source was widely promoted. 500W, 1000W, 2000W and 3000W medium-high power fiber laser sources were promoted by leading laser manufacturers like Raycus. Fiber laser soon took up big market share in the laser market and gradually replaced the solid state light pumping laser. Then some laser device manufacturers developed handheld laser welding machine with 500W fiber laser as the laser source. And this was the 2.0 version of the handheld laser welding system.

Comparing with the 1.0 version, 2.0 version of handheld laser welding machine greatly improved the welding efficiency and processing performance and was able to weld materials with below 1.5mm thickness which require certain degree of strength. However, the 2.0 version was not perfect enough. The ultra-high precision focal spot requires the welded products to be also precise. For example when welding 1mm materials, if the weld line is bigger than 0.2mm, the welding performance would be less satisfactory.

To meet the demanding weld line requirement, laser device manufacturers later developed the wobble style handheld laser welding machine. And this is the 3.0 version.

The main feature of wobble style handheld laser welding machine is that the welding focal spot is wobbling with high frequency, which makes the welding focal spot be adjusted to 6mm. That means it can weld the products with big weld line. Besides, the 3.0 version is smaller than the 2.0 version in size with lower price, which drew great attention once it was launched the market. And this is the version that we see in the market now.

If you are careful enough, you might notice there is often a cooling device under the fiber laser source inside the handheld laser welding system. And that cooling device is used to keep the fiber laser source from overheating, since overheating will lead to decreased welding performance and shorter lifespan. In order to fit in the handheld laser welding system, the cooling device needs to be rack mount type. S&A RMFL series rack mount chillers are especially designed for handheld laser welding machine from 1KW to 2KW. The rack mount design allows the chillers to be integrated into the machine layout, saving considerable space for the users. Besides, the RMFL series rack mount chillers have dual temperature control which offers independent cooling for the laser head and the laser effectively.

Materials that handheld laser welder is applicable to process

Featuring high welding speed, high precision & efficiency and smooth weld line, handheld laser welder has become a “heated” technique in the industrial welding sector. There are a wide variety of applications for handheld laser welder, but many people don’t know what materials it is applicable to process. Today, we would like to list some of the most common materials below.

1.Die steel
Handheld laser welder is applicable to weld die steels of various types and has fantastic welding performance. 

2.Carbon steel
Using handheld laser welder to weld carbon steel can achieve good welding effect and the welding quality depends on the content of the impurity. In order to get the best welding quality, preheating needs to be performed if the carbon steel has over 25% of carbon so that micro-crack won’t occur.


3.Stainless steel
Because of high welding speed and small heat affecting zone, handheld laser welder can reduce the negative effect brought by big coefficient of linear expansion in stainless steel. Plus, the weld line doesn’t have bubble, impurities and so on. Comparing with carbon steel, stainless steel can achieve narrow weld line of deep penetration welding, for it has low thermal conductivity coefficient, high energy absorption rate and melting efficiency. Therefore, it is very ideal to use handheld laser welder to weld stainless steel. 

4.Copper and copper alloy
Welding copper and copper alloy can easily have the not-bonding and not-welding problem. Therefore, it is better to use handheld laser welder with focused energy and high power laser source and do the preheating. 

In fact , in addition to the above mentioned metals, handheld laser welder can also bond different types of metals together. Under certain conditions, copper & nickle, nickle & titanium, copper & titanium, titanium & molybdenum, brass & copper can be bonded respectively with handheld laser welder. 

Handheld laser welder is often powered by 1-2KW fiber laser. To keep the handheld laser welder at its optimal, the fiber laser source inside needs to be properly cooled. At this time, a water chiller system would be ideal. 

S&A Teyu RMFL series rack mount chiller is specially designed for cooling handheld laser welder from 1-2KW. The rack mount design of the chiller allows it to be placed in a movable rack, which increases its mobility. In addition, the RMFL series water chiller system has a front-mounted fill port together with a water level check, so it is very easy for users to do the water filling and checking. More importantly, the rack mount chiller features ±0.5℃, which is very precise.

The prospect of handheld laser welding system

Handheld laser welding system has been trending laser welding equipment in the past few years. It focuses on large work pieces that are placed in long distance. It is so flexible that the space limitation is not a problem any more and it replaces the traditional light path. Therefore, handheld laser welding system makes outdoor mobile welding become reality.

The principle of handheld laser welding system is to post high energy laser light on the surface of the work piece. The laser and the material will interact with each other so that the inside of the material will melt and then cool down to become a welding line. This kind of welding features delicate welding line, fast welding speed, easy operation and no consumables required. In thin metal welding, handheld laser welding system can perfectly replace traditional TIG welding. 

There are a few advantages of handheld laser welding system

1.Wide welding range
Generally speaking, handheld laser welding system is equipped with a 10m extension fiber line, which enables long-distance non-contact welding;

2. High flexibility
Handheld laser welding system is often equipped with caster wheels, so users can move it wherever they want;

3 . Multiple welding styles
Handheld laser welding system can achieve welding of any angles and also perform small power cutting as long as users replace the welding brass mouthpiece with cutting brass mouthpiece. 

4. Excellent welding performance
Handheld laser welding machine features small heat affecting zone, high depth of weld, delicate welding line without post-processing. 

Comparing with TIG welding, handheld laser welding system is able to perform welding of different metals with fast speed, little deformation, high precision, applicable to welding tiny & precise parts. And these can not be achieved by TIG welding. As for energy consumption, handheld laser welding system is only half of TIG welding, which means the production cost can reduce by 50%. In addition, handheld laser welding system doesn’t require post-processing, which is also cost saving. Therefore, it is believed that handheld laser welding system will replace TIG welding and becomes more and more widely used in metal processing industry. 

Most of the handheld laser welding system is powered by fiber laser of 1000W-2000W. Fiber laser in this power range tends to generate a big amount of heat. To guarantee the normal running of the handheld laser welding system, its fiber laser source must be properly cooled. S&A Teyu develops RMFL series water chillers specifically designed for handheld laser welding system and features rack mount design. These rack mount chillers are equipped with an easy-to-read level check and convenient water fill port, which provides so much convenience to the users. The temperature stability of these laser chiller units is up to ±0.5℃. For more detailed parameters of RMFL series rack mount chillers, click https://www.teyuchiller.com/fiber-laser-chillers_c2
