Chapter 212 The Progress of the Second Guarantee Welding Machine
Chapter 212 The Progress of the Second Guarantee Welding Machine
When Mu Yang and Zhou Chen arrived, several R&D personnel were testing welding.
A total of two special welding machines were assembled on site, which are specially used for welding circumferential welds, and two semi-automatic welding machines are used for manual welding tests. In addition, welding machines of foreign brands such as Panasonic and Lincoln are also installed.
When developing new products, you will buy one or two devices of the same type and a better brand to compare and study to see what is good and what is not good about other people's products.
A lot can be learned by comparison.
The test welding sample of the special welding machine is a barrel body with a plate thickness of 2 mm, a diameter of 250 mm, and a length of 200 mm, and the butt girth weld is welded. This type of product is used very much, such as pipe butt welding, pressure vessel cylinder butt girth weld , Oil receivers for automobile maintenance supplies and sandblasting machine barrel girth welds, etc.
When Mu Yang and Zhou Chen arrived, the on-site R&D personnel became nervous.
This is the company's No. 1 and No. 2 bosses, so they have to take their opinions seriously.
Especially the boss, the equipment being developed is all the technical information given by the boss, who is more familiar with the situation than them. Sometimes they can't figure out some profound questions for a long time, and they have to ask the boss for advice. It's just that the boss is busy, and sometimes they are too embarrassed to ask the boss for advice.
Their project team has a total of 30 R&D personnel. It has only been a few months since its establishment. At present, the team is running well. There is no intrigue. This is what the boss emphasizes every time. Unity, no one can replace, or rather clean up.
"Hello Chairman, Mr. Zhou."
When Mu Yang and Zhou Chen walked past them, the R&D personnel stopped what they were doing and greeted them.
Mu Yang smiled and nodded: "Well, everyone has worked hard, Mr. Zhou and I came over to check the situation."
After speaking, I came to a special welding machine, where a 6000-frame industrial high-speed camera was installed to capture the fusing dynamics and frequency of arc droplets during welding. There is also an arc fluctuation measuring instrument, which specially records the arc change and arc stability during welding. There are other rare measuring instruments.
Welding application personnel such as welders and welding engineers will not have access to these instruments and will only use them for welding machine testing.
These instruments are all purchased by Mu Yang, and he can use them himself.
Mu Yang roughly scanned the scene and asked several R&D personnel: "How much current and voltage fluctuations are there during welding?"
"The current floats within 10.0A, and the voltage is ±0.1." A senior engineer replied respectfully.
"Well, this is a relatively good situation." Mu Yang nodded and analyzed, "Even if it is a foreign brand welder, it is rare to be able to control the current within 10A, but the voltage is possible. Generally, the welder is within 20A. It is normal, if it fluctuates tens of A, the voltage fluctuates more than 5V, the welding machine must be bad.
If the current and voltage are unstable, the arc will be unstable, so the quality of the weld must be unstable and there will be a lot of spatter. "
There are many items to be tested for welding machines, such as current and voltage stability, vibration during welding operation, noise level, arc stability, fusing condition and frequency, arc anti-electromagnetic interference, etc., as many as dozens of items.
The on-site R&D personnel listened quietly and carefully to what the boss said, and they could learn a lot from every analysis by the boss.
The knowledge mentioned by the boss cannot be found by looking for information. It must have been summed up by the boss himself.
Everyone admires the boss from the bottom of their hearts, and some people still have a little admiration for the boss.
They know that the company's laser is developed by the boss, and it is the world's top level.
In the eyes of most employees, Mu Yang is the boss of the group.
But in the eyes of these R&D personnel, Mu Yang is a scientific research monster. He can be said to be omnipotent in the mechanical industry. This is what the experts of the laser project team, Dr. Wang Hai and Dr. Mo Qiu said.
Their arc welding machine project team consisted of 30 people, with Fei Fei including 4 doctors, 16 master graduates, and the rest were undergraduates.
Undergraduates who have graduated for more than five years and graduate students who have graduated for more than one year can dare to call themselves engineers. It is not necessary to have an intermediate engineer certificate.
[In the Xinghai Group, there is already a new method of classifying employees. P is the technical route, which is somewhat similar to Ali's classification method.
P1-P2 = technician (college student)
P3=Assistant Engineer, Technician (generally graduates with two majors, college students who have worked for 2-4 years)
P4=Assistant engineer, technician (211 undergraduate graduates, graduate students within one year of graduation)
P5=Engineer (undergraduate students who have graduated for more than five years, graduate students who have graduated for more than one year)
P6=senior engineer; P7=expert; P8=senior expert (Mo Qiu)
P9=Researcher (Wang Hai, Fei Fei)
P10=Senior Researcher; P11=Scientist
P12=Chief Scientist
P13=Mu Yang
The technical department currently has 72 people, including 2 P9 researchers, 4 P7 and P8 experts, 12 P6 senior engineers, 26 P5 engineers, and 25 P4 assistants.
At the same time, there is a set of management mechanism corresponding to the P level:
M1=P6 supervisor
M2=P7 Manager (Deputy Production Manager, Quality Manager)
M3=P8 Senior Manager (Production Manager, Technical Manager)
M4 =P9 Director (Vice President Zhang Xiaofeng)
M5= P10 Senior Director (Zhou Chen, Yang Hai), General Manager of Subsidiary
M6=P11 group vice president and other O; M7=P12 group CEO
M8=P13 Mu Yang]
Mu Yang continued: "How big is the roundness error of the workpiece? You must know that the current and voltage may change as the height of the welding torch from the workpiece changes."
A P6 senior engineer replied: "We just took this into consideration. The roundness error of the selected workpieces does not exceed ±0.2mm. Do dozens of pieces, we are just talking about experimental use, and process them according to your requirements, boss."
"The workpiece has been measured, and what the processing master said may not be accurate."
"Every piece has been measured and meets the requirements. Here is the diameter data record sheet for each barrel." A person who recorded the data took the record sheet to the boss.
"Well, don't look at it, just confirm it, I just remind you." Mu Yang replied.
Zhou Chen usually doesn't talk about the details of scientific research. He usually asks the project team leader to monitor the progress of research and development. Even if he is a doctor, it is impossible for him to study every project in depth.
As for Mu Yang, it is more appropriate to say that he is the chief scientist.
Mu Yang knows the company's situation, and knows that it is not a good phenomenon for R&D personnel to rely too much on him, but at present, the company only has one or two scientific research projects, and the company has no scientific research background, and does not rely on him. Let me give you some pointers, if you really have to wait for them to produce qualified samples, it may take half a year or even a year.
The market waits for no one.
Without Mu Yang, this R&D team, which has not been working together for a long time, would not even be able to reach the first-class level in China.
With Mu Yang's information, they have reached the domestic first-class level and are close to the world's first-class level.
With Mu Yang's guidance, they can reach the top level in the world.
It is too difficult for them to develop world-class products by themselves. If it is that easy, other manufacturers can do it too.
And Muyang knows that his role is a catalyst to accelerate the growth of the company's R&D team and accumulate experience and technical data. If they want to independently develop world-class products without relying on Muyang, this time may take a short time. It can take one or two years, or a few years at most.
Mu Yang saw that there were twenty or thirty samples welded on the ground, and asked the tester next to him:
"Which one is the newly welded sample?"
"These are all of them. They're just soldered, and they're a little hot. Boss, be careful when you look at them. I'll just flip them over for you."
"It's okay, bring me a pair of gloves, it's more convenient for me to do it myself." Mu Yang knew that he was not a fool.
A research and development personnel gave him a pair of gloves. After Mu Yang put them on, he flipped the sample and observed the surface condition of the weld.
The welding toe is well fused and transitioned perfectly, and the surface of the weld seam has no obvious potholes and is relatively smooth.
Especially the welding spatter rate that Mu Yang is most concerned about, even if it is a small particle, he did not see it.
Perfect!
To be able to weld so well, the welding machine and technology are the main factors. Others, welding consumables also have a great influence on the quality.
After reading it, Mu Yang commented: "The spatter rate is extremely low, it has really achieved ultra-low spatter, but it is not yet true zero splash, and there are still a few small particles, but it can't be seen when spraying paint. It doesn't matter. You can call How about the range, don't just a few small ranges, if the user can't adjust it, it will be embarrassing."
"I have tried all the current and voltage ranges that can be welded." The tester replied.
"It looks like there is nothing wrong with the appearance. Do the mechanical performance test of the weld, just do the side bending, add a macro, and look at the material structure to see what is going on." Mu Yang smiled easily, "From the appearance Say, you have made it, but it depends on the internal situation.
However, in my experience, it's not a problem. "
When everyone heard the boss say this, a big stone in their hearts finally fell, and their faces were full of joy.
After watching the experiment of the Erbao welding machine, Mu Yang and Zhou Chen went to the workshop.
The workshop is very busy now. As the production manager said, many passages in the workshop are blocked, and the trucks coming in from the company are lined up, unloading and loading.
Now the company has insufficient space to meet the mass production of the second-guarantee welding machine, and must entrust most of the business.
Mu Yang confessed to Zhou Chen: "Mr. Zhou, it is estimated that within a month, our second-guarantee welding machine can enter the mass production stage. The company has insufficient space. Try to arrange outsourced processing, but to ensure the quality, we can now find an outsourcer. When choosing an outsourced factory, you must follow the process and avoid personal relationships or other channels. With more and more business in the group, corruption will inevitably occur.
I don't tolerate corruption. If the company suspects that someone has embezzled 100,000 yuan, even if it costs 1 million yuan to investigate and collect evidence, he must be found out and fired. "
The bigger the enterprise, the easier it is for corruption to breed, such as accepting kickbacks from suppliers, playing mahjong with suppliers, opening casinos, accepting food and drink in violation of regulations, etc.
The most likely to happen is the salesman in charge of outsourcing processing, as well as procurement.
Mu Yang thought of the "Seven Fallen Sons" of Alibaba in later generations, the CEO, the general manager of Taobao Juhuasuan, the vice president of human resources, the vice president of the group, the vice president of Youku Tudou, the vice president of Ali Pictures, the president of Youku... were all arrested for their involvement in corruption. Cut off the horse.
They are all high-level.
Can it be said that the salaries of these high-level executives are poor? That's impossible. Is there anyone with an annual income of less than one million yuan.
For these people, high salaries and honesty are useless. It can only be said that greed is unlimited.
What Mu Yang can do is to standardize the process from the beginning, and not let the power be used too much.
"Okay." Zhou Chen nodded, keeping the boss's explanation in mind.
At the same time, although the boss's words did not refer to him, it also made him think.
As soon as Mu Yang came back to the office, he received a call from the city leader, saying congratulations to Xinghai Group for winning the lawsuit.
After being courteous with the city leaders, after hanging up the phone, he made a complaint: it's an afterthought.
It has been several days since the lawsuit, and the phone call came late. It seems that the R Min Daily has played a role. Mu Yang and these people are not in the same way. When they are in the lawsuit, they don’t call to comfort them, and stay away. Afraid of trouble.
Mu Yang can also understand, after all, they don't have a deep friendship with him.
