TEYU Chiller, S&a Chiller's Co2 Laser Chiller

Recently, the first airborne suspended train in China underwent a test run in Wuhan. The entire train adopts a technology-themed blue color scheme and features a 270° glass design, allowing passengers to overlook the city scenery from within the train. It truly feels like science fiction becoming a reality. Now, let's learn about the application of laser technology in the airborne train:

Laser Welding Technology
The top and body of the train must be well welded to ensure proper structural integrity for stable train operation. Laser welding technology enables seamless welding of the train's roof and body, ensuring a perfect combination and balanced overall structural strength of the train. Laser welding technology also plays an important role in the welding of critical components on the track.

Laser Cutting Technology
The front of the train has a bullet-shaped and aerodynamically efficient design, achieved through precise sheet metal cutting using laser cutting technology. Approximately 20% to 30% of the train's steel structural components, especially the driver's cab and body auxiliary devices, utilize laser technology for processing. Laser cutting facilitates automated control, making it suitable for cutting irregular shapes. It significantly shortens the production cycle, reduces manufacturing costs, and enhances product quality.

Laser Marking Technology
Within the quality control system, a micro-indentation marking and barcode management system is introduced. By utilizing a laser marking machine, component codes with a marking depth of 0.1mm are engraved on sheet metal parts. This allows for the transfer of original information regarding steel plate materials, component names, and codes. Effective management enables full-process quality tracking and enhances the level of quality management.

According to S&A Teyu experience, the current of carbon steel fiber laser cutter closed loop water cooling system suddenly increases due to :


1.There is too much dust on the closed loop water cooling system;

2.There is not enough supply of air where the laser water cooling system is located;

3.The water temperature is too high;

4.The chiller’s voltage is too low;

The compressor of the chiller is aging.

Laser processing has experienced a rapid development in the past 10 years in China and is gradually replacing traditional techniques. From screen printing to laser marking and engraving, from punch press to laser cutting, from chemical agent washing to laser cleaning, these are great changes in the processing techniques. These changes are more eco-friendly, more efficient and more productive. And that is the progress brought by the laser technique and a trend that is "meant to be".





Handheld laser welding technique develops rapidly







In terms of welding, the technique also experiences changes. From the original normal electrical welding, arc welding to the present laser welding. The metal oriented laser welding has become the most important application for the time being. Laser welding has been developing in China for nearly 30 years. But in the past, people often used small power YAG laser welding machine to do the welding job, but small power YAG laser welding machine was in low level of automation and required manual loading and unloading. What's more, its working format was pretty small, which made it hard to process big workpiece. Therefore, laser welding machine didn't get wide application at the beginning. But later, in the past few years, laser welding machine has have big development, especially the advent of fiber laser welding and semiconductor laser welding. For the time being, laser welding technique has been widely used in automobile, aerospace and other high-end industries.







In the end of 2018, handheld laser welding machine began to gain its popularity. Thanks to the reduce cost of fiber laser and the established technique of fiber transmission and handheld welding head.







The reason why handheld laser welding machine gets popular so fast is that it is easy to use and flexible. Comparing with traditional laser welding machine which has high technical threshold, handheld laser welding machine doesn't require fixture and motion control. It is more acceptable for most of the small-medium enterprises.







Take stainless steel welding for example. Stainless steel welding is quite normal in our daily life and most of them adopt normal TIG welding or spot welding. After many years of development, manual operation is still the major operation and there are quite a lot of these kinds of welders. You can see the trace of TIG welding in stainless steel objects in kitchenware, bathroom products, doors and windows, furniture, hotel decorations and many other industries. TIG welding is often used to weld thin stainless steel sheet or pipe. But now people just replace TIG welding by handheld laser welding and they are very similar in operation. For handheld laser welder, people will only need the training of less than a day, which shows great potential of handheld laser welding machine replacing TIG welding.







It is a trend that handheld laser welding machine replaces TIG welding machine







TIG welding often requires melted welding wire for connection, but that often lead to protruding on the weld part. However, handheld laser welding doesn't require welding wire and has smoother weld part. TIG welding has been developing for many years and has the biggest user base while handheld laser welding is a kind of novel technique with fast development and only accounts for small use base. But it is a trend that handheld laser welding will replace TIG welding. For the time being, with the cost being considered, TIG welding is also very popular.







Nowadays, TIG welding machine only costs around 3000RMB. As for handheld laser welding machine, in 2019, it cost over 150000RMB. But later as the competition becomes more fierce, the number of handheld laser welding machine producers also increased, which lowers the price to a great extent. Nowadays, it only costs around 60000RMB.







TIG welding often realizes as spot welding at certain spots to reduce manual labor and materials. But for handheld laser welding, it performs welding all the way through a welding line. This makes handheld laser welding more stable than TIG welding. The common powers of handheld laser welding machine include 500W,1000W,1500W or even 2000W. These powers are sufficient for thin steel sheet welding. The current handheld laser welding machines have become more and more compact and many parts including industrial process chiller can also be integrated into the whole machine with more flexibility and lower price.

In winter, people live in high latitude area would consider adding anti-freezer into metal 3D laser printer closed loop water cooling system so that the circulating water won’t freeze because of low temperature. But here comes the question - should the anti-freezer be diluted with water? The answer is YES. That is because anti-freezer is corrosive, which is bad for the components of the laser water chiller unit. In addition, it is suggested to pour it out when the weather becomes warm and refill the chiller with fresh purified water or clean distilled water.
