Sixue Building, Room 305.

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

Fatty glanced at the two books on Muyang's desk, and was a little curious. Xinghai Machinery already has two self-developed devices. He probably understands that it has only been a long time. Could it be that he has started a new move again?

"Well, I plan to study laser welding."

"I don't know much about this, but I feel it's very advanced. I've only heard that the plasma welding or other welding of Xinghai Machinery can't be replaced. What advantages does it have?"

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

"The difference is huge, and it cannot be said that they are bad. If the welding methods are subdivided, there are dozens of them, and the most suitable application fields of 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! "

Like 0.5-2mm thin plates (term: sheet metal), it is very suitable to use hand-held laser welding. The technical requirements for welders are very, very low. As long as you train for a few hours and feel good, you can weld products. If the feel is worse , Welding can also be welded for 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, and the fat man was like a sponge, attracting knowledge, and the more he listened, the fresher he felt.

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

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

"Uh, in layman's terms, 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, you can only read books on lasers. "

Fatty nodded, Mu Yang said it was relatively easy to understand, not too deep.

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

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

Only when you study it thoroughly can you easily tell others about it.

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

admire!

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

He was able to come to class, which has already given the teacher a lot of face, but Mu Yang said that staying in the classroom, the learning atmosphere is better, and being a student should be like a student.

You see, the ideological awareness is too high, and 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 broad and deep. You can also learn about organic conversations in the future. This industry has a very good prospect and a high salary." Mu Yang suggested.

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

Muyang continued to study laser welding.

He will handle hand contact laser welding and robotic laser welding from 2020 to 2022, but his research is not deep, mainly on applications.

Laser welding equipment involves a lot of optical knowledge. Mu Yang has studied for a long time, but he has not understood 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 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 smash experiential learning.

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

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

Finally to the monochromaticity, coherence, particle inversion principle of optics...

A lot of laser knowledge inserted into his brain, fusion.

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

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

2 Optical resonator: In order to concentrate the beam, amplify, and propagate along the axial direction.

Others, Mu Yang did not intend to study further, one is that he has insufficient experience, and the other is that he wants to study transparent lasers and produce them. It is estimated that a large number of fifth-level skills are required, and even some disciplines need to reach sixth-level skills.

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

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

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

Still have to buy a foreign brand laser.

This is 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, the domestic laser manufacturers include Maxphotonics in Shenzhen, which was established in 2004; Raycus in Wucheng, which was established in 2007, and JPT.

These three companies are all early-established fiber laser manufacturers. They have little strength at present. They are all in their infancy and only occupy a small market share in China after a few years.

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

The big head is still seized by the foreigner industry leader IPG (Xiong Country), 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, T-coherent, and NLIGHT.

Like a wolf leopard, it seizes the domestic laser market and "plunders" a lot of domestic wealth.

This is what Mu Yang does not want to see!

The era of exchanging technology for the market is over.

In the past, my country's lasers basically relied on imports, which were expensive and had a long supply 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 tough, but someone has to walk it.

Of course, the price of fiber lasers is currently 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 those manufacturers who make high-end stainless steel products.

For domestic manufacturers, what if your products are good, but your equipment is too expensive, and my production costs will rise. If I want to make money, who will buy your equipment if there is no profit margin.

so,

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

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

It's not that it's impossible, but the higher the power, the higher the price, and it will double and increase the power consumption.

In 2020, the market price of domestic brand 1000W fiber lasers for welding will be 17,000 yuan, and 2000W will be 40,000 yuan;

The same power of foreign brands, 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 2000W lasers of foreign brands is 55,000 yuan.

At that time, a handheld laser welding machine assembled with a foreigner's 2000W laser was sold for about 140,000 yuan at the end.

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

In 2009, Muyang checked the data, and the market price of the 1000-watt welding fiber laser from IPG, the leader in the fiber laser industry, was about 65,000 yuan.

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

Other configuration costs are not high, a few thousand dollars can be done.

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

If Muyang is made, it will be the first domestic manufacturer of 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 large, and there is really no such thing at present.

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

One terminal sells more than ten to two hundred thousand yuan, and the market is monopolized.

If it is too expensive to sell, those domestic business owners would rather use other welding methods instead, such as employing people to cover the cost.

You can start to sell more expensively, sell to those local tyrant bosses, and then cut the price after the sales volume is stuck, and try to make profits by volume.

Well, just do it.

No matter how much money he earns, what Mu Yang likes to do most is monopoly.

Cool!

yeah yeah

While he can make money, he can also help the domestic manufacturing industries to upgrade equipment, improve product quality, improve work efficiency, and then resell the products abroad, at a low price, kill all similar products in other countries and squeeze them out. manufacturing.

Maybe this is a bit delusional, but it is no problem to have a great impact on the foreign manufacturing industry.

This kind of thing is actually the same as Xinghai Machinery's foundry. The products of various valve factories related to surfacing STL6 sell better and more and more overseas orders are made. This phenomenon cannot be highlighted all at once.

With the low cost of domestic labor and high-quality anti-Japanese foreign brands, the foreign counterparts' manufacturing industry cannot continue to operate. Only by completely withdrawing from this industry can the domestic manufacturing industry be considered a victory~www.mtlnovel.com~ Muyang Deseyi Yes, just calm down and start dry.

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

Laser is the core, Muyang purchases foreign brands;

Welding gun and water tank, make it yourself.

After the achievement point system is opened, it will develop domestic lasers by itself, breaking the monopoly of foreign high-end lasers.

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

He has used hand-held laser welding for a long time, except that the lens inside is afraid to move, he has repaired it many times, and he is familiar with it.

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

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

Muyang immediately decided to set up the project and started to make preparations. After returning to the company after class, he asked the personnel department to prepare for recruiting. At the same time, he started the design himself. It is estimated that the design will be completed in a month.

The boss makes decisions directly, which is much faster than a company with a complex organizational structure. They also have to conduct research, write reports, make reports, hold meetings to discuss, discuss capital investment, and analyze income. There are many processes, and they may not be implemented in the end.

Of course, this decision is risky.

But who is Mu Yang?

A reborn person who is open, he can avoid many risks, he also has an achievement point system, and the general direction of technical research can not be wrong!

Just do it!

But don't be reckless. When the group is large enough, it is also necessary to establish a general strategy department to analyze it specifically for him. After all, people inevitably make mistakes.

It is right to be cautious, but once the direction is chosen, it must be executed decisively. Click to download this site APP, massive novels, free to read!
