Sixue Building, Classroom 305.

"Boss Mu, are you watching the laser?"

The fat man looked at the two books on Mu Yang's desk and was a little curious. Xinghai Machinery currently has two independently developed equipment. He roughly understood. How long has it been? Has he started a new move?

"Well, I plan to study laser welding."

"I don't know about this, and I feel it's very advanced. I have only heard that the plasma welding or other welding of Xinghai Machinery cannot be replaced. What are its advantages?"

Fatty is just a welding novice. He has only been to Xinghai Machinery a few times, and has seen plasma welding, gas-protective welding and TIG welding. He has learned a little fur and knows more than other students.

"There are great differences, and we cannot say that they are not good. If the welding method is subdivided, there are dozens of types, and each of them has the most suitable application fields."

Muyang continued,

"Simply put, it has much less welding deformation than welding methods such as second-conservation welding, argon arc welding, submerged arc welding, etc.

Therefore, it is more suitable for welding thin plates!”

For example, 0.5-2 mm thin plate (term: sheet metal), handheld laser welding is very suitable. The technical requirements for welders are very low. Just train for a few hours and feel good, and you can weld the product. If the feel is worse, you can weld it in two or three days.

Moreover, the welded welds are very beautiful and even.

This is also an effect that other welding methods cannot achieve!

Muyang slowly said like an old professor, the fat man was like a sponge, attracting knowledge, and the more he listened, the more he felt the fresher he felt.

The classmates next to him also joined in the fun and listened. Mu Yang's speech was easy to understand, but some of the knowledge points were still difficult to understand.

The fat man absorbed a lot of knowledge in a short time, and his head became a little swollen, which understood most of the more he could understand than the classmates next to him, but he was a little confused: "I still don't understand, why is the laser welding less deformed?"

“Well, in layman's terms, the weld width is only 2-3 mm, which means that the unit length energy heated to the base material is much less than other welding methods, and the weld width is very uniform.

You understand, if you don’t understand, you can only read laser books.”

The fat man nodded. Mu Yang was quite easy to understand and didn't go into it too deeply.

Other students also praised: "Yozi, you have studied it very thoroughly."

"Yes, we are still learning the most basic knowledge, and Boss Mu has already researched it across the border."

Only by studying it thoroughly can we simply popularize science to others.

Otherwise, what laymen listen to is the professional knowledge of encyclopedia, rather than in-depth and concise popular science knowledge.

admire!

They often see Mu Yang reading extracurricular books and know that he had finished his freshman courses long ago, and the teacher also exempted him from his homework.

He was already very proud of his appearance in the teacher, but Mu Yang said that staying in the classroom will have a better learning atmosphere, and he should be like a student when he is a student.

You see, their ideological awareness is too high and they can't learn it.

If you have money and a company, you will go to Mao School!

"It's just fur. The knowledge involved in this laser is too broad and deep. If you have the opportunity in the future, you can also learn about it. The industry has a good prospect and high salary." Mu Yang suggested.

Everyone chatted for a while and was about to prepare for class and returned to their respective seats.

Muyang continued to study laser welding.

He took over touch-held laser welding and robot laser welding from 2020 to 2022, but his research was not deep and mainly for application.

Laser welding equipment involves a lot of optical knowledge. Mu Yang has studied it for a long time but has not figured it out. In this way, he reviewed high school physics and university physics, but the knowledge involved in light is still relatively shallow.

It doesn’t matter if you don’t understand now, it doesn’t matter if you’re difficult to learn, you can cheat!

This is Mu Yang’s favorite thing to do.

Find relevant subjects and directly study experience.

Let’s start with simple laser types, YAG lasers, CO2 lasers... fiber lasers, etc.;

Go deeper into the structure and principles of lasers: resonant cavity, semiconductor pump source...

Finally, the monochromaticity, coherence, and particle inversion principle of optical...

A lot of laser knowledge is inserted into his brain and fused.

About ten minutes later, Mu Yang figured out the two conditions for laser generation.

1 Pump source: In order to achieve particle reversal, atoms continue to jump and do not attenuate, providing a continuous stream of photons.

2 Optical resonant cavity: In order to concentrate, amplify the light beam and propagate in the axial direction.

Mu Yang did not intend to conduct further research on other aspects. First, he did not have enough experience, and second, he wanted to study lasers and produce them. It is estimated that a large number of level five skills are required, and some subjects must even reach the level six skills level.

Anyway, he was not able to develop, manufacture and manufacture lasers in the early stage.

I can't study it, so I can buy a laser to assemble it myself.

There are many types of lasers, and Muyang plans to use the fiber laser with the most extensive application in welding in the future.

I still have to buy foreign brand lasers.

This is helpless!

The pricing power of my country's laser industry is still unavailable and has been monopolized abroad for a long time.

At present, domestic laser manufacturers include Chuangxin from Shenzhen Stock Exchange, which was established in 2004; Ruike from Wucheng, which was founded in 2007, and Jeput.

These three companies are all early fiber laser manufacturers. They currently have no strength and are in the initial stage and only occupy a small domestic market share a few years later.

Even if it occupys a small number of markets, it has broken the monopoly of foreign companies in the laser field and directly lowered the price of imported products, which has made an indelible contribution.

Datou is still being seized by foreign industry leader IPG (Xiong Guo), which has been established in 1991 and is a world-renowned developer and manufacturer of high-performance fiber laser and amplifier products.

There are also well-known foreign fiber laser brands such as T-melli MPF, T-Core, and NLIGHT Ennai.

It seized the domestic laser market like a wolf and leopard, and "plundered" a large amount of domestic wealth.

This is something Mu Yang doesn’t want to see!

The era of exchanging market for technology has passed.

my country's lasers used to rely basically on imports, with high prices and long supply cycles.

In the cutting-edge technology industry, Chinese people must have their own top brands, interrupt foreign brand monopoly, and even drive them out of the country.

The road is difficult, but someone has to go.

Of course, fiber lasers are currently monopolized by foreigners. Before domestic lasers can make a big breakthrough, lasers are not much cheaper.

Even if Muyang is assembled successfully, the price of the whole machine will be very high and can only be sold to manufacturers who make high-end stainless steel products.

For domestic manufacturers, even if your products are good, your equipment is too expensive, and my production costs will rise. I want to make money, but who will buy your equipment without profit margin?

so,

Muyang plans to weld a plate of 0.8-3 mm, which is also the general thickness range of sheet metal products. Normally, the power of welding lasers is between 360-500W (watts). Choosing a 1000W fiber laser for welding is enough.

But in fact, those who don’t know how to do things will choose a fiber laser for welding with a power of 2000W.

It’s not that it doesn’t work, but the greater the power, the higher the price, and doubles it and increases the power consumption.

In 2020, the market price of domestic brands of 1,000W welding fiber lasers was 17,000 yuan, and 2,000 yuan was 40,000 yuan;

Foreign brands with the same power are about 1.5-2 times the price of domestic brands.

Of course, it is cheaper to purchase a large amount of money, and it is estimated that it is only about 20% off the market price. The 2,000W laser from a foreign brand is worth 55,000 yuan.

At that time, a handheld laser welding used a foreigner's 2000W laser was finally sold for about 140,000 yuan.

Gross profit space = 14-5.5-Other configuration costs are about 0.5=80,000 yuan!

In 2009, Mu Yang checked the information and found that the 1,000-watt fiber laser for welding, the leading fiber laser industry, was sold for about 65,000 yuan.

If you purchase a large amount of money, you will probably be able to buy it at 55,000 yuan.

Other configuration costs are not high, and can be handled for a few thousand yuan.

The production cost of a handheld laser welding is about 60,000 yuan.

If Muyang makes it, it will be the first handheld laser welding equipment in China.

No, it should be the world's first handheld laser welding equipment!

I guess foreigners think the market is not big, and there is really no one at the moment.

However, in China, sheet metal welding is very widely used, and laser welding is very suitable.

One terminal sells more than 100,000 or 200,000 yuan, and the market monopoly.

If the sale is too expensive, those domestic business owners would rather use other welding methods instead, such as using people to fill the cost.

You can start selling more expensively and sell them to rich bosses. After the sales volume is stuck, then lower the price and make profits with volume.

Well, that's it.

No matter how much money you make, Mu Yang likes to do the most is monopoly, and he feels like it is just one word.

Cool!

Yeah
