Rebirth 2008: I Can Make Money Reading

Chapter 110 Profit Margins of Handheld Laser Welding (13)

Si Xue Building, Room 305.

"Boss Mu, are you looking at the laser light?"

The fat man glanced at the two books on Muyang's desk, and was a little curious. Xinghai Machinery already had two self-developed equipment. He probably understood how long it had been. Did he start a new action again?

"Well, I plan to study laser welding."

"I don't know much about this. I think it's very advanced. I've only heard that Xinghai Machinery's plasma welding or other welding can't replace it. What advantages does it have?"

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

"The difference is very large, and it cannot be said that they are not good. If the welding methods are subdivided, there are dozens of them, and the most suitable application fields for each are different."

Mu Yang went on to say,

"Simply put, it has much less welding deformation than welding methods such as secondary welding, argon arc welding, and submerged arc welding.

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

For thin plates of 0.5-2mm (term: sheet metal), hand-held laser welding is very suitable, and the technical requirements for welders are very, very low. Only a few hours of training is required, and the product can be welded if the hand feel is good. If the hand feel is not good , It can be welded after two or three days.

Moreover, the welded seam is very beautiful and uniform.

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

Mu Yang came slowly like an old professor, Fatty was like a sponge, absorbing knowledge, the more he listened to it, the fresher he felt.

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

The fat man absorbed a lot of knowledge in a short period of time, his head was a little swollen, and he understood most of it better than the students next to him, but he was a little confused: "I still don't understand, why is the deformation of laser welding so small?"

"Well, generally speaking, the width of the weld is only 2-3 mm, that is, the energy per unit length heated to the base metal is much less than other welding methods, and the width of the weld is very uniform.

Get it, if you don’t understand it, you can only read books on lasers. "

Fatty nodded. What Mu Yang said was relatively easy to understand, without going too deep.

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

"Yes, we are still learning the most basic knowledge, Boss Mu has already cross-border research."

Only when the research is thorough can it be easy to popularize science to others.

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

admire!

They often see Mu Yang reading extracurricular books, knowing that he has already finished his freshman courses, and the teacher also waived his homework.

He was able to come to the class, which is already very good for the teacher, but Mu Yang said that staying in the classroom will make the learning atmosphere better, and when a student is a student, he should behave like a student.

You see, the ideological consciousness is too high, they can't learn it.

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

"It's just fur. The knowledge involved in this laser is too wide and too deep. You can also learn about it if you have a conversation in the future. The prospect of this industry is very good and the salary is high." Mu Yang suggested.

After chatting for a while, everyone was about to get ready for class, and returned to their seats.

Mu Yang continued to study laser welding.

He will take over hand-held laser welding and robot laser welding from 2020 to 2022, but the research is not deep, mainly the application.

Laser welding equipment involves a lot of optical knowledge, and Mu Yang studied for a long time, but he didn't understand it. So he reviewed high school physics and college physics, but the knowledge related to light is still relatively shallow.

It doesn't matter if you don't understand it now, it doesn't matter if it's difficult to learn, just hang up!

This is Mu Yang's favorite thing to do.

Find relevant disciplines and directly learn by experience.

Start with simple laser types, YAG lasers, CO2 lasers... fiber lasers, etc.;

Go deep into the structure and principle of the laser: resonator, semiconductor pump source...

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

A large amount of laser knowledge was inserted into his brain and fused.

After about ten minutes, Mu Yang figured out the two conditions for the laser to be produced.

1 Pumping source: In order to achieve particle inversion, atoms continue to jump without attenuation, providing a steady stream of photons.

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

Others, Mu Yang did not plan to study further, one is lack of experience, and the other is to research and produce transparent lasers, it is estimated that a lot of five-level skills are required, and even some subjects need to reach six-level skills.

Anyway, he didn't have the ability to develop and manufacture lasers in the early stage.

Can't research, you can buy a laser to assemble it yourself.

There are many types of lasers, and Muyang intends to use fiber lasers, which are the most widely used in welding applications in the future.

Still have to buy foreigner brand lasers.

This is very helpless!

The pricing power of my country's laser industry is still unable to be independent, and has been monopolized by foreign countries for a long time.

At present, domestic laser manufacturers include Chuangxin in Shenzhen, established in 2004; Raycus in Wucheng, established in 2007, and JPT.

These three companies are all fiber laser manufacturers established earlier. They are currently in their infancy, and they have only occupied a small amount of domestic market share after a few years.

Even if it occupies a small amount of the market, it has broken the monopoly of foreign companies in the field of lasers and directly lowered the price of imported products.

The big head is still dominated by the foreigner industry leader IPG (Xiong Guo), which was founded in 1991 and is a world-renowned developer and manufacturer of high-performance fiber lasers and amplifiers.

There are also well-known foreign fiber laser brands such as TRUMPF, COHERENT, and NLIGHT.

Seize the domestic laser market like wolves and leopards, and "plunder" a large amount of domestic wealth.

This is what Mu Yang doesn't want to see!

The era of exchanging the market for technology is over.

In the past, my country's lasers basically relied on imports, which were expensive and had a long delivery cycle.

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

The road is hard, but someone has to walk it.

Of course, at present, the price of fiber lasers is monopolized by foreigners. Before the domestic lasers fail to make a big breakthrough, the lasers will not be much cheaper.

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

For domestic manufacturers, even if your products are good, so what, but your equipment is too expensive, my production cost will rise accordingly, I want to make money, no one will buy your equipment if there is no profit margin.

so,

Muyang intends to weld 0.8-3mm boards, which is also the common thickness range of sheet metal products. The normal use of welding laser power is between 360-500W (watts), and a 1000W welding fiber laser is enough.

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

It's not impossible, but the greater the power, the higher the price, and it doubles and increases power consumption.

In 2020, the market price of domestic brand 1000W fiber laser for welding is 17,000 yuan, and that of 2000W will be 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 in large quantities. It is estimated that it is only about 20% off the market price. The median value of foreign brand 2000W lasers is 55,000 yuan.

At that time, a hand-held laser welder assembled with a foreigner's 2000W laser was sold for about 140,000 in the final sale.

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

In 2009, Mu Yang checked the information, and the market price of the 1,000-watt welding fiber laser of IPG, the leader in the fiber laser industry, was about 65,000 yuan.

If purchased in large quantities, it is estimated that 55,000 yuan can be bought.

The cost of other configurations is not high, and it can be done for a few thousand dollars.

The manufacturing cost of a hand-held laser welding machine is about 60,000 yuan.

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

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

It is estimated that foreigners feel that the market is not big, and there is really no such thing at present.

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

A terminal sells for more than 100,000 to 200,000 yuan, and the market is monopolized.

If it 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 to sell it more expensive, sell it to those rich bosses, wait for the sales volume to be stuck, and then reduce the price to fight for profits.

Well, that's it.

Regardless of how much money is earned, Mu Yang's favorite thing to do is to monopolize, and it feels like a word,

Cool!

yeah yeah

While he can make money, he can also help those domestic manufacturing industries to upgrade their equipment, improve product quality, and improve work efficiency, and then resell the products abroad. manufacturing industry.

Perhaps this is a bit delusional, but it is no problem that it can have a great impact on the foreigner's manufacturing industry.

This kind of thing is actually the same as that of Xinghai Machinery OEM. The products of various valve factories related to surfacing welding STL6 are selling better and better, and there are more and more overseas orders. This phenomenon cannot be highlighted all at once.

The low-cost domestic labor and high-quality anti-war foreign brands have made it impossible for foreign counterparts to operate in the manufacturing industry. Only by completely withdrawing from this industry can the domestic manufacturing industry be considered a victory.

Mu Yang stuttered for a while, then calmed down and started working.

The three main structures of handheld laser welding equipment: laser, welding torch and cooling water circulation system equipment.

Laser is the core, and Muyang purchases foreign brands;

Welding torch and water tank, make it yourself.

After the achievement point system is opened, it will develop its own domestic lasers to break the monopoly of foreign high-end lasers.

The circulation system of the water tank is relatively simple, and the structure of the welding torch is relatively complicated.

He has used handheld laser welding for a long time, except for the lens inside, he dare not move, he has repaired it himself many times, and he is familiar with it.

Because the operator needs to hold the welding torch to weld, the welding torch should not be too heavy, otherwise the workers will feel sore hands after long-term operation.

Light and small is the design direction of the handheld laser welding torch.

Mu Yang immediately decided to establish the project and started to make preparations. After returning to the company after class, he asked the HR department to prepare to recruit people. At the same time, he started designing by himself, and it was estimated that the design would be completed in a month.

It is much faster for the boss to make a decision directly than a company with a complex organizational structure. They have to conduct research, write reports, make reports, hold meetings to discuss, discuss capital investment, and analyze benefits. There are many processes, and they may not be able to implement them in the end.

Of course, such a decision is risky.

But who is Mu Yang?

A cheating rebirth, he can avoid a lot of risks, he also has an achievement point system, the general direction of technology research can't be wrong!

Just do it!

But you can't do it recklessly. After the group is large enough, it is necessary to establish a general strategy department to analyze it for him. After all, people are bound to make mistakes.

It is right to be cautious, but after choosing a direction, you must execute it decisively.

The second update is at 12:00, and the third update is at 23:00 in the evening
